speculative dinosaur evolution

The North American strider is a perfect example of the group, being quite small and slight, with a coat of insulating plumage and atrophied arms. Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Late epoch of the Triassic period. These creatures continue to thrive to the present day, as, among others, hmungos thundering across North America, saurolopes sweeping through the plains of Africa, and dendrosaurs swinging about the trees of Australia. All Tomorrows(2008) is a book written and illustrated by Nemo Ramjet. Welcome to Speculative Evolution! Cazadins (Papillotyrannus pauli) also known as White Cazadins range from just south of the Amazon to Patagonia, and eat a variety of smaller dinosaurs, mammals, reptiles, and invertebrates. After 65 million years ago, Mammals has rise and became the dominant species. A later well-known primitive tyrannosauroid is the Early Cretaceous Eotyrannus from Britain, a sleek 5-meter predator with relatively long forelimbs. An earlier find from Europe strongly hints at the group's origins, among the many superb fossil finds of the mid-Eocene Messel Shales are three exquisitely preserved specimens of the little tyrannosaurid Saltotyrannus nanus and the small Errosaurus borealis from Oligocene epoch deposits in western Canada. Cryptozoologicon The Biology, Evolution, and Mythology of Hidden Animals. The most common scenario in serious speculative evolution projects. Errosaurus borealis, an extinct member of the Errosauridae dating back to the Oligocene Epoch. Like the hyenas of home-Earth, bruisers are squat, compact predators, with powerful jaws, bone-crushing teeth, and a keen sense of smell. – Leonard Bernstein, Candide. When they were rediscovered, they were thought to be either a subspecies of thunderbird or imperial sabre tyrant subspecies which made its way to North America during the Pleistocene epoch. No Marketing Blurb Fortunately, most if not all of the content was saved before the shutdown. In Spec, the large tyrannosaurids (including the genus Tyrannosaurus) continued to thrive up until 55 million years ago. Immediately noticeable on any errosaurid are the furry protofeathers that cover almost the entire body. I was first introduced to the concept back in 2016, when I discovered Wayne Barlow's (I think I spelt his last name right) amazing book, Expedition. Spec Dinosauria: Maniraptora. Homo Intelligens: The Evolution Of Man V, The Reliquary and Illustrated Archaeologist,: A Quarterly Journal and Review Devoted to the Study of Early Pagan and Christian Antiquities of Great Britain, Volume 5|Llewellyn Frederick William Jewitt, Dino Finder Dot-to-Dot: Connect the Dots & Color|Jerald D. Harris, 150 Years of Baseball|Rh Value Publishing This scenario is divided in three main sub-groups: K-T absence scenario: Basically the most common scenario on speculative evolution projects, usually located in a parallel earth where dinosaurs never became extinct and continued to evolve during the Mesozoic. The North American strider (. Others however, had no competition. This is their story. EVOLUTION follows the ebb and flow of the fortunes of one group of creatures as they change and adapt to their world somewhere on the horn of Africa. Some other species, like the therizinosaurs, which in habit the Great Plains, will stand and fight with long claws. 12K Views. The thunderbird (Smilotyrannus brontus) is the largest carnivore of the forests of the North America, most notably in the Pacific Northwest and Western United States, growing up to lengths of 8.5 meters long. However, during the Eocene and Oligocene epochs, a wide range of smaller, more bizarre tyrannosauroids had evolved. Watch popular content from the following creators: Maxwellthuem(@communisttardigrade), Maxwellthuem(@communisttardigrade), Brandon Turman(@bturman95), Roach(@kekkuda.cosplay), Tony Turner(@tonymuyo) . They aren't found anywhere in Asia at all, you are more likely to find one in Eurasia. Some seem not to have survived the competition with the northern fauna; for example, abelisaurs have so far not been found in sediments between 55 and 25 million years in age in India or elsewhere in the Northern continents. This causes the world's temperature to quickly drop and causes By John Conway C.M. With only a few notable exceptions such as the Volleur, which is still undergoing observations, most errosaurids are small, cursorial predators. The Nian can be found through out the colder parts of Asia. The Buffalo-Bill is considered to be a bit of a controversial member of the sabre-tyrants. It ushered in a new era in the evolution of vertebrate life on Earth. Analogous to the Home-Earth coyote as the North American Strider is to a Home-Earth fox, the Courour is as much as scavenger as it is a predator, and having a wider range of prey to choose from than the North American Strider, is better able to expand its resource base when food is scarce. The Specworld, is, to put the matter simply, a parallel Earth. Instead, the dinosaurs rule, and have ruled for some time. Having split off soon after the errosaurs evolved their downy coats, bruisers developed in the direction of scavengers. Oakelies are roughly twice the size of their Mongolian cousins, and, as with many tyrannosaur species, females are larger than males, often reaching lengths of 4 meters. Found inside – Page 1Now, for the first time, a sweeping collection of the most interesting of Jehol’s avian fossils is on display in this beautiful book. 65 million years ago a meteorite hit the Yucatán Peninsula in south-eastern Mexico. These creatures also tend to run on the very tips of their toes, giving them a distinctive, ostrich-like gait. This group consists of four different clades. This blog is devoted to the the discussion of speculative zoology, an open field that looks at the possibilities for the paths that life could have or might take given that certain events do or do not take place. They are generally small animals, rarely over two meters long. It tells the story of the human race in the next billion years, counting from the date man colonized other planets to his defeat at the hands of another species, to the formation of an empire of the descendents of humanity. Their Eurasian relatives seemed to hold on out for a while longer than the tyrannosaurs native to North America, sustaining themselves on the ceratopsians and gigantic lambeosaurs that roamed Eurasia from the Cretaceous to the Oligocene epoch. Half the size of their mainland relatives due to the demands of island living, these species of Bruisers specialize in hunting the island hadrosaurs in the area. The single exception to their normal aggressive behavior takes place during the spring mating season, when the males range about looking for prospective brides. Phobotyrannids were pug-snouted, robust creatures with huge teeth, their faces and bodies adorned with numerous spines and hornlets. The second largest species of the genus, Errosaurus, and named after the most famous species of dinosaur, Tyrannosaurus rex, the King Strider can be found roaming areas of Western North America and even as far north of Canada. Found insideKarl P.N. Shuker has collected evidence of these mysterious, somewhat mythical creatures in THE BEASTS THAT HIDE FROM MAN. Shuker provides entertaining, solidly researched tales about extraordinary animals. However, their bone-crushing bite more than makes up for their lack of size with only a few notable exceptions, the errosaurines are small cursorial predators. Welcome to Speculative Evolution! But as longtime Nature editor Henry Gee argues in Across the Bridge, despite these giant strides and our deepening understanding of how vertebrates fit into the tree of life, the morphological chasm between vertebrates and invertebrates ... However, unlike its Pacific Northwestern relative, the legs are longer and more slender than the thunderbird; a particular reason why the Buffalo-Bill more widespread throughout North America when compared to the thunderbird. Uncover the twists and turns that led to the great milestones of evolution: the extinction of the dinosaurs, the discovery of fire, the Industrial Revolution, and more. All Yesterdays is a book about the way we see dinosaurs and other prehistoric animals. Speculative evolution may either talk about organic builds in other planetary servers or show the alternate development process of the game Outside. In North America, they were already gone when the massive herds of ceratopsians like Brontoceratops robustus had vanished. All members of the clade Nototyranninae posses only the two outer toes of the foot, the inner toe and the hallux being atrophied to mere slivers of bone, invisible beneath layers of skin and muscle. They specialize in dispatching the small viriosaurs, therizinosaurs and dinoceratopsians which inhabit this area. Some even talk about how builds would spend their evolution points in the distant future. The smilotyrannines thus abandoned the massive chomping techniques of their ancestors in exchange for a more refined and precise armor-piercing attack aimed at strategically disabling its prey rather than crunching it with one bite. The mammals did not spread across the land and sea as the largest animals in existence; whole swaths of Mammalia, including dolphins, horses, and humans, have failed entirely to evolve. While courours are the dominant small-game predators on grasslands across North America, they are by no means the only carnivore in that habitat. In short, the impact marked the end of the Mesozoic with the great Cretaceous-Palaeogene (or K-Pg) mass extinction event. Dear Sir, Madam, Hemaphrodite, or It; Basically, speculative evolution is about what could have evolved in the past, what should evolve in the future, and what might evolve on alien planets. Thrillosopher. Dinosaur Revolution is a four-part American nature documentary produced by Creative Differences. Dinosaurs evolved during the Middle or Early Triassic, between 230 and 250 million years ago, as part of a larger radiation of archosaurs. There, where the trees are pillars and the branches a green ceiling, can be found the legendary "Hall of Heorot" of Spec, where creatures of the shade make a living, far removed from their sun-loving relatives of the Golden Afternoon. Dinosaurs are split into two principal groupings, the Saurischia (including among others sauropods and theropods, which in turn include birds) and the somewhat less diverse, but still successful Ornithischia (including ceratopsians, ornithopods, and ankylosaurs). The craniofacial air-sac system is very well developed, helping to keep the animal cool during lengthy physical exertions. The divergence between these two occurred far back in the Mesozoic, with both groups evolving from small, bipedal herbivores. This is, however, not a problem for a sufficiently fast and endurant errosaurid, such as a cazadin. Only a full-grown adult hmungo, which is in healthy condition, is safe from the being preyed on by these monsters. Both planets orbit their middle-aged, G-class stars at the distance of a single astronomical unit, possess continents and oceans in near-identical configuration (differences include the absence of man-made geography), and a single, large moon. Man After Man: An Anthropology of the Future (Hardcover) by. Spec Dinosauria: Hadrosauria. Atacama Cazarrio, Notovenator atacamas (Atacama Desert). Since this is a recently discovered predator, not much of its behavior is known at the moment. They must then set off to establish their own territories, never to see their parent again. https://speculativebiology.fandom.com/wiki/The_Speculative_Dinosaur_Project This niche also brings them into occasional competition with the smaller North American Strider, which hunts much of the same prey. A forest bruiser is a powerful, 1.8 meter-long hunter-scavenger that tracks prey and carrion through the dim recesses of Eurasia's northern forest, mostly by dint of its excellent senses of hearing and smell. The mammals conquered the land, the water, and even the air (although the last remaining dinosaurs, the neornithean birds, are unquestionably dominant at least in the air – they actually contain about half of all amniote species). No tests have been conducted thus far on the species to determine which is more energy efficient...though this researcher theorizes that it is similar to RL's kangaroos. Created by. Also known as the American Khinner, this agile, but medium sized errosaur grows up to lengths of about 15 feet long, a little bit larger than its Asian relative, and it is the top predator in Southern North America. The theory of evolution is a naturalistic theory of the history of life on earth (this refers to the theory of evolution which employs methodological naturalism and is taught in schools and universities). Both planets are clothed in a layer of atmosphere (mostly nitrogen and oxygen), and, although our home Earth is rather warmer (and still warming) and more generally chaotic in climate, both have similar global weather. Dougal Dixon. Discover short videos related to speculative evolution on TikTok. Speculative Evolution Wiki is a FANDOM Lifestyle Community. But until the year 2050, the first dinosaurs have been cloned. ... and stand on two legs to reach high into branches or watch out for dangerous dinosaurs. However, a recent in depth analysis revealed that the Eurasian tyrannosaurs, most were more specialized in hunting the massive lambeosaurs in the area, most notably Sauropodimimus. In a series of events that mirror the relationships between the two species of rhynchoraptor from Australia, jagdpanther and strumtiger to be more specific, the Wendigo and Yarper seem to have a deep rooted hatred for the species and will go to violent lengths to remove each other from the environment. The following is in the words of Hendrickson who she and all of her colleges survived the encounter: "On that day, all was peaceful and clam, the only sounds being the buzzing of insects and trumpeting bellows of hmungos en route to the warm southern grasslands of North America from their nesting grounds near the arctic, with a few species of singers and vanguards following the massive hadrosaurs. The first few lines of primitive dinosaurs diversified rapidly through the Triassic period; dinosaur species quickly evolved the specialized features and range of sizes needed to exploit nearly every terrestrial ecological niche. A 1988 book, written by Scottish geologist Dougal Dixon about what life on world would be like if the meteor that killed the dinosaurs didn't hit the Earth. 1,324 likes. The ornithischians also evolved swept-back hips, probably as an adaptation to accommodate larger, plant-digesting guts. Over the eons, both groups have experimented with carnivory, omnivory, and herbivory, but it is still safe to say that many saurischians are predators while many ornithischians eat plants. Clade Smilotyranninae reached its apex during the Pleistocene, producing such forms as the recently extinct Smilotyrannus horridus, a giant to rival even the famed Tyrannosaurus rex (although it has been suggested that these were simply giant morphs of living species). Of these last, the meter-long white cazadin is the most common, a ubiquitous small predator of the Pampas. - Evolution of a Dinosaur & Jurassic Creations! A sabre-tyrant attack thus involves one or two quick hit-and-run strikes followed by a more leisurely final deathblow once the prey has been sufficiently weakened. Covering nutrition, physiology, growth, and skeletal structure and body plans, this volume presents the most up-to-date knowledge about the biology of these enormous dinosaurs. The more fleet-footed errosaurs having made their kill, the bruisers will rush in screeching, teeth gnashing, and drive their foes from their prey. The largest of the striders, taiga striders (Errosaurus arahorni) are ubiquitous on the steppes of northern Eurasia. Bruisers (Contusisaurus sp.) cover. These evolved around the time when the massive chasmosaurs went extinct and when hadrosaurs were starting to evolve in to smaller and more agile forms like Procurvihadrus specensis. There is no crater under the coast of Spec's Yucatán, nor the shocked quartz, micro-diamonds, soot, or clay layer (rich in iridium, osmium, gold and other rare metals) spawned by the impact that in our home timeline ended the Cretaceous Period and ushered in the Palaeogene Period. , with a few species of singers and vanguards following the massive hadrosaurs. Media in category "Speculative evolution" The following 3 files are in this category, out of 3 total. Apart from a few basal representatives like the Australian cedunasaurs, the tyrannosaurs, and the archaeoplumes, all living coelurosaurs are birdlike maniraptors. This is the current Spec page with Yahoo Groups, unfortunately, being shut down back in December 2019. The deseado dancer (Papillotyrannus rancori) is medium sized cazadin and rather large by South American standards, growing up to lengths of 3.5 meters long. This blog is devoted to the the discussion of speculative zoology, an open field that looks at the possibilities for the paths that life could have or might take given that certain events do or do not take place. 96 Comments. With such a wide range of area at its disposal, it comes as no surprise that these 10-meter long monsters have a massive variety of prey items to choose from: hadrosaurs, therizinosaurs, viriosaurs, vanguards, draks, birds and mammals. Speculative Evolution Forum, A Decade of Wonders. Though it should be noted that these. This engaging book reveals the latest findings about dinosaur anatomy and behaviour, evolution, diversity and lifestyle, and is lavishly illustrated with artwork, photographs and artistic reconstructions that bring these iconic creatures to ... The Grendels of Spec are bruisers, powerful tyrannosaurs that most often scavenge. frostbitepandaaaaa reblogged this from speculative-evolution.

The Blimpers are my headcanonical descendants of All Tomorrows' Striders. When it gave way to the Cretaceous, the temperature rose to 64.4 degrees Fahrenheit. For this project I'm going over the..... 1. Sabre-tyrants communicate with low near-infra-sound growling, something you're as likely to feel as hear. A native to the Atacama Desert, this species has evolved from the Cazarrino (Notovenator pictus), though it has since lost the pack-hunting tendancy, though it will gather in large groups for such occasions as the beaching of a large-bodied marine animal. Though raalos are only 6.5 meters (the female is always larger) long, they can bring down full-grown mooras, dorsas and cuinoccos. It will even prey on the ungulipedes that inhabit the island, most notably the Cuinocco and the Dwarf Orth. Should it be taken seriously? B logging has revolutionised the way we communicate our interests and spread news. This book is a compilation of various articles from the blog, Tetrapod Zoology(currently hosted at www.scienceblogs.com/tetrapodzoology). Even giving the likes of the bruisers are run for their money. Spec Dinosauria: Gondwanaviformes. For the most part, Spec is exactly like our home timeline (also called Home-Earth). Now, the smilotyrannines occupy the top-predator niches across the northern reaches of both Eurasia and North America and are restricted to a single genus, Smilotyrannus. Only their fossils remain, but thanks to paleoartists most people have a good idea of what these creatures looked like. The world of paleoart and its artists are the subject of this richly illustrated work. Coprolites of †Tyrannosaurus already contain fragmented bones, and †Triceratops skeletons have been found with scratches that indicate a †Tyrannosaurus made sure it had scraped all meat off the bones. However, the some species of tyrannosaur still retain the great size of their giant ancestors. Spec Dinosauria: Mattiraptoroidea. They regularly migrate away into Britain's dark oak forests, shrouded in mist and cloaked in gloom. The (non-neornithean) dinosaurs, once the largest land animals on the planet, have been reduced to mere stone and imagination. Far more common than the ceratopians, however, are the ornithopods, which live on every continent but Antarctica. Spec's dinosaurs are wildly diverse, with species ranging from hummingbirds to gihugrongos and sabre-tyrants. But what if none of this history were true? Pursuit-predators of surpassing skill, these six-meter-long giants even hunt the formosicorn herds of therizinosaurs, running a hapless yale or panha to exhaustion before ripping the animal apart with powerful tyrannosaurian jaws. Download it once and read it on your Kindle device, PC, phones or tablets. Most modern saurischians, however, are coelurosaurs, two-legged and feathered. This blog is devoted to the the discussion of speculative zoology, an open field that looks at the possibilities for the paths that life could have or might take given that certain events do or do not take place. Spec Dinosauria: Laurasiornithopoda. The khinner (Errosauroides mongoliensis) is a small and swift errosaurid, growing up to lengths of 10 feet long, that lives in Mongolia and northeastern China. For most of their evolution, this was the norm for tyrannosaurs, and such forms as the gigantic nine-to-ten-meter Yutyrannus and Sinotyrannus were perfect examples of this. Copyright © 2001 – 2005 Daniel Bensen and David Marjanović Graphic design and illustrations by Tiina Aumala, 2003 – 2005, "Once one dismisses The rest of all possible worlds, One finds that this is The best of all possible worlds." During the period of dinosaur predominance, which encompassed the ensuing Jurassic and Cretaceousperiods, nearly every known land animal larger than 1 meter in length was a dinosaur. Credit: T. Bertelink via WikiCommons CC BY-SA 4,0 The Hadean is the first geological eon of Earth’s history. But there has been no confirmed contact with intelligent life, until now. Though undeniably speculative when it was published in 1998, The New Dinosaurs was greatly influenced by the state of dinosaur … The imperial sabre-tyrant, at over ten meters in length, is the largest terrestrial carnivore on the planet, uncomfortably reminiscent of such lost giants as Tyrannosaurus and Giganotosaurus. I think this is because After Man takes place in our actual world, and is a speculative look at what could be, while The New Dinosaurs is a work of alternate history, where evolution took a different turn millions of years ago. The imperial sabre-tyrant can now only be found on the icy plains around the Arctic Circle, in both Siberia and northern Canada (although fossils indicate they once ranged as far south as France). All living tyrannosauroids belong to a single, but very diverse lineage, the Errosauridae that contains over thirty living species in Spec. Though not as big as the imperial sabre-tyrant, it is still an intimidating and ferocious predator. Found insideImprobable Destinies will change the way we think and talk about evolution. This blog is devoted to the the discussion of speculative zoology, an open field that looks at the possibilities for the paths that life could have or might take given that certain events do or do not take place. A single bite would easily drive these sabres through a therizinosaur's hide, leaving deep wounds that would severely weaken the animal through shock and blood-loss. Post Aug 03, 2009 #1 2009-08-03T15:34. Like all bruisers, the Siberian is heavily-built and squat, with short legs and powerful head and neck muscles powering huge bone-crushing teeth. This elegantly illustrated volume is a journey through more than two centuries of remarkable discovery. The generalized viriosaurs of the Americas are also antarctornithopods, having split from their Australian cousins some time in the very early Cenozoic and walked to South America from Australia via Antarctica. Nevertheless, Grendels are not restricted to the coast. The year is 2724, humanity has spread out among the stars. Found inside – Page 1This field guide offers a unique look at the creatures that populate the Star Wars galaxy. Ironically, these predators did not grow to become the Tyrannosaurus-like monsters as did the smilotyrannines of Asia and North America. A very odd book, almost a part of the growing genre of "speculative evolution", but based on real fossils and cleverly questioning our interpretations of those fossils. Want to Read. ... Abiogenesis is speculative without evidence. However, both worlds respond to the same laws of nature. Speculative Evolution Wiki is a FANDOM Lifestyle Community. We were originally assigned to this area to observe the ceratopsians after Jack Horner, John Scannella and Denver Fowler's (they were accompaning us from Montana State University) reports of some sort of american ceratopsian were proven correct after all, they were in Canada observing the ceratopsians in that area while famous Chinese paleontologist Xu Xing was leading his students to observe some of the newly discovered fauna on the islands of Java and Sumatra. Spec World is created by people who actually have paleontological training...and a nerdy sense of humor. Add to Cart. With a lithe, agile body and long slender legs, it uses them to chase down prey, most notably the viriosaurs. These early forms also were the first tyrannosauroids to experiment with head ornamentation; thin, singular crests running the length of the skull akin to those of the unrelated Monolophosaurus. Early birds. Thus, these deinonychosaurs occupy the most of the large predator niches in South America, while the tyrannosaurs are relegated to the small, running-predator niches that deinonychosaurs usually take on the other continents. Theatre Mode (alt+t) Fullscreen (f) Stream Chat. In the wake of the K-Pg extinction, mammals exploded into dazzling array of giant forms. Cazadins can still be found in the prairies of southern North America, but their diversity is greatest in South America which they first reached 3 million years ago and found the land essentially empty of competition, as the last noasaurs had died out a few hundred thousand years before and the small oviraptorids sharing the niche being much slower than the notoventaorinaes, allowing them to be the main cheetah-like predators of South America. The troodontids are now a shadow of their former glory while ornithomimids have vanished forever. The plumage is black and iridescent green, and the tiny, sunken red arms give the misleading impression of having been ripped out of their sockets. 312 Favourites. The pelvic girdle is odd in that the pubis is bent slightly backwards, but does not lie against the illium as in raptors and therizinosaurs. Little did I know my thought were to be proven correct.". Mounted skeletons of the infamous Tyrannosaurus rex, the terror of the Late Cretaceous, are a guaranteed drawcard to any museum gallery.
