Members of its single Compsognathus longipes could grow to around the size of a turkey. Paleontologists have found two well-preserved fossilsone in Germany in the s and the second in France more than a century later. Today, C. Many presentations still describe Compsognathus as "chicken-sized" because of the size of the German specimen, which is now believed to be a juvenile. Compsognathus longipes is one of the few dinosaur species whose diet is known with certainty: the remains of small, agile lizards are preserved in the bellies of both specimens. Teeth discovered in Portugal may be further remains of the genus. Although not recognized as such at the time of its discovery, Compsognathus is the first theropod dinosaur known from a reasonably complete fossil skeleton. Until the s, it was the smallest-known non- avialan dinosaur, with the preceding centuries incorrectly labelling them as the closest relative of Archaeopteryx. However, dinosaurs discovered later, such as CaenagnathasiaMicroraptor and Parvicursorwere even smaller. The largest Compsognathus specimen is estimated to have weighed somewhere between A Dinosaur Called Tiny. Compsognathus were small, bipedal with long hind legs and longer tails, which they used for balance during locomotion. The forelimbs were smaller than the hindlimbs. The hand bore two large, clawed digits and a third, smaller A Dinosaur Called Tiny that may have been non-functional. The skull had five pairs of fenestrae skull openingsthe largest of which was for the orbit eye socket[7] with the eyes being larger in proportion to the rest of the skull. The lower jaw was slender and had no mandibular fenestra, a hole in the side of the lower jawbone commonly seen in archosaurs. The teeth were small but sharp, suited for its diet of small vertebrates and possibly other small animals, A Dinosaur Called Tiny as insects. Its frontmost teeth those on the premaxilla were unserrated, unlike those further back in the jaw which were flattened and more strongly recurved. The number of digits on the hand of Compsognathus has been a source of debate. Halstead depicts the as an amphibious dinosaur capable of feeding on aquatic prey and swimming A Dinosaur Called Tiny of reach of larger predators. Peyer confirmed these conclusions. Some relatives of Compsognathusnamely Sinosauropteryx and Sinocalliopteryxhave been preserved with the remains of simple feathers covering the body like fur, [14] promoting some scientists to suggest that Compsognathus might have been feathered in a similar way. However, no feathers or feather-like covering have been preserved with Compsognathus , in contrast to Archaeopteryxwhich are found in the same sediments. A Dinosaur Called Tiny Peyer, inreported skin impressions preserved on the side of the tail starting at the 13th tail vertebra. The impressions showed small bumpy A Dinosaur Called Tiny, similar to the scales found on the tail and hind legs of Juravenator. Like Compsognathusand unlike Sinosauropteryxa patch of fossilized skin from the tail and hindlimb of the possible relative Juravenator starki shows mainly scales, though there is some indication A Dinosaur Called Tiny simple feathers were also present in the preserved areas. The German Compsognathus fossil itself most likely came from the Painten Formation of the Kapfelberg locality, specifically dated to the uppermost Kimmeridgian stage Wagner discussed the specimen briefly inwhen he coined the name Compsognathus longipes[23] and described it in detail in Although Alain Bidar originally described the specimen as a separate species called Compsognathus corallestris[12] Ostrom, Jean-Guy Michard and others have since relabeled it as another example of Compsognathus longipes. A Dinosaur Called Tiny Heinrich Fischer had originally labeled a partial foot, from the Solnhofen area, as belonging to Compsognathus longipes. Though this identification was rejected by Wilhelm Barnim Dames in[32] Friedrich von Huene nevertheless in provisionally referred the A Dinosaur Called Tiny to Compsognathus. Jens Zinke in assigned forty-nine teeth from the Kimmeridgian Guimarota formation of Portugal to the genus. These were not identical to those of C. In Virginia Morell renamed a related Chinese form, Sinosauropteryx primainto a Compsognathus prima ; [35] this has found no general acceptance. The genus Compsognathus gives its name to the family Compsognathidaea group composed mostly of small dinosaurs from the late and early periods of China, Europe and South America. The A Dinosaur Called Tiny includes Aristosuchus[36] Huaxiagnathus[37] Mirischia[38] Sinosauropteryx[14] [39] and perhaps Juravenator [40] and Scipionyx. Some, such as theropod expert Thomas Holtz Jr. For almost a century, Compsognathus longipes was the only well-known small theropod species. This led to comparisons with Archaeopteryx and to suggestions of an especially close relationship with birds. In fact, Compsognathusrather than Archaeopteryxpiqued Huxley's interest in the origin of birds. Below is a simplified cladogram placing Compsognathus in Compsognathidae by Senter et al. In a study conducted by Bruce Rothschild and A Dinosaur Called Tiny paleontologists, nine foot bones referred to Compsognathus were examined for signs of stress fracturebut none were found. The remains of a lizard in the German specimen's thoracic cavity show that Compsognathus preyed on small vertebrates. This A Dinosaur Called Tiny turn led to the conclusion that its predators, Compsognathusmust have had sharp vision and the ability to rapidly accelerate and outrun the lizard. The French specimen's gastric contents consist of unidentified lizards or sphenodontids. Peter Griffiths interpreted them as immature eggs in A well-preserved fossil of a Sinosauropteryxa genus related to Compsognathusshows two oviducts bearing two unlaid eggs. These proportionally larger and less numerous eggs of Sinosauropteryx cast further doubt on the original identification of the purported Compsognathus eggs. InWilliam Sellers and Phillip Manning estimated a maximum speed of During the late Jurassic, Europe was a dry, tropical archipelago at the edge of the Tethys Sea. The fine limestone in which the skeletons of Compsognathus have been found originated in calcite from the shells of marine organisms. Both the German and French areas where Compsognathus specimens have been preserved were lagoons situated between the beaches and coral reefs of the Jurassic European islands in the Tethys Sea. The same sediments in which Compsognathus have been preserved also contain fossils of a number of marine animals such as fish, crustaceans, echinoderms and marine mollusks, confirming the coastal habitat of this theropod. No other dinosaur has been found in association with Compsognathusindicating that these little dinosaurs might in fact have been the top land predator in these islands. Children's A Dinosaur Called Tiny books commonly feature Compsognathus. For a long time they were unique in their small size, as most other small dinosaurs were discovered and described a century or more later. In The Lost World: Jurassic Parkone of the characters A Dinosaur Called Tiny identifies the species as " Compsognathus triassicus ", combining the genus name of Compsognathus longipes with the specific name of Procompsognathus triassicusA Dinosaur Called Tiny distantly related small carnivore featured in the Jurassic Park novels.

What is the smallest dinosaur? Not all dinosaurs were giants! This article is part of our Dinosaur Facts series. When most people think about dinosaurs they imagine very big animals. However, there were plenty of dinosaurs that were the same size as — or even smaller than — humans. Modern birds, such as the Bee Hummingbird the smallest living bird would fill up all of the top spots. It is, of course, impossible to obtain accurate measurements of the size and weight of living dinosaurs. One thing to remember when learning about dinosaurs is that nearly everything we know about them comes from fossils. Scientists A Dinosaur Called Tiny extremely skilled at making these kinds of estimates. They can make educated guesses as to not only the size and appearance of dinosaurs, but also their diet and A Dinosaur Called Tiny. However, until we invent a time machine, or create a real-life Jurassic Park, then there is no real way of knowing for sure how big or small dinosaurs were! Anchiornis huxleyi was a tiny, long-legged, winged dinosaur. Covered in feathers, it is seen by many as an evolutionary link between dinosaur and bird. It lived in what is now China, in the late Jurassic period. With long feathers found on both fore and hind limbs, Anchiornis huxleyi may have been a better glider than it was a flyer — if it left A Dinosaur Called Tiny ground at all! One of the smallest dinosaurs yet discovered, Anchiornis huxleyi weighed between and grams 3. Incredibly, scientists can even tell what color Anchiornis huxleyi was from pigment cells still present in fossilized specimens. They found that it was mainly dark grey and black, A Dinosaur Called Tiny a red crown and white stripes on its wings. Anchiornis huxleyi is the only species in the genus Anchiornis. Epidexipteryx hui was a small bird-like dinosaur. It lived in what is now A Dinosaur Called Tiny Mongolia in China around to million year ago, in the mid to late Jurassic period. The most striking feature of Epidexipteryx hui was its four long tail feathers. Scientists think that these provided balance for climbing in trees rather than aiding flight. It is likely that Epidexipteryx hui would have been a glider if it left the ground at all. Epidexipteryx hui belongs on a smallest dinosaur list, being only Compsognathus was once thought to be the smallest dinosaur. Discoveries of several smaller species means that Compsognathus no longer holds this title, but it is a fascinating dinosaur nonetheless. Compsognathus was a small dinosaur that walked on its two hind legs. It was a theropod, which is a group of meat-eating dinosaurs that also includes — believe it or not — giants such as T Rex and Spinosaurus. Compsognathus may have been covered in feather-like structures, as were several closely-related dinosaurs. However, no evidence has been found of this in any Compsognathus fossils. Compsognathus is actually a genus A Dinosaur Called Tiny, which in biology means a group of closely related species. However, there is only one species in the genus, Compsognathus longipes the scientific names of species always have two words. This turkey-sized mini-dinosaur was around A Dinosaur Called Tiny meter 3. Compsognathus fossils have been found in Germany and France. It lived around million years ago, during the Jurassic period. In fact, everything we know about Parvicursor comes from one incomplete specimen consisting of just a pelvis and hind legs. The only Parvicursor species is Parvicursor remotus. It lived in what is now Mongolia during the period. Parvicursor remotus could well be the smallest dinosaur yet discovered. It was around 39 cm 15 in in length and weighed only grams 5. Microraptors were small, bird-like dinosaurs. They were among the first feathered dinosaurs to have been discovered. It is thought that the largest Microraptors would have reached around 1. Pigment cells have been found in A Dinosaur Called Tiny specimens. These indicate that Microraptors were black, possibly with an iridescent hue similar to that of the modern-day starling. Whether or not Microraptors could fly — or were actually gliders — is unknown, but studies suggest that they A Dinosaur Called Tiny capable of true flight. A Dinosaur Called Tiny Microraptor fossils have been found, and it is thought to have been one of the commonest dinosaurs in its ecosystem. Although three Microraptor species have been described, it is thought that they all might actually be examples of the same species, Microraptor zhaoianus. Of these, either Anchiornis huxleyi or Parvicursor remotus could be considered the smallest. If you want to A Dinosaur Called Tiny a dinosaur expert, check out some of our other dinosaur pages:.

Museums are filled with gargantuan skeletons of dinosaurs and Ice Age animals that dwarf modern day species. It can come as a surprise, therefore, that there were many tiny reptiles, amphibians, and mammals living alongside Tyrannosaurus Rex and . In a way, it's much more difficult to identify the smallest, sometimes cutest dinosaurs and prehistoric animals than the biggest ones—after all, a tiny, foot-long might easily have been the juvenile of a much larger species, but there's no mistaking the evidence for a ton behemoth. Some tiny prehistoric creatures, however, are absolutely unique. With its feathers and four primitive wings one pair each on its forearms and hind legsthe Microraptor might easily have been mistaken for a bizarrely mutated pigeon. This was, however, a genuine raptorin the same family as Velociraptor and Deinonychusalbeit one that only measured about two feet from head to tail and weighed A Dinosaur Called Tiny a few pounds. The king of the dinosaurs, Tyrannosaurus Rexmeasured 40 feet from head to tail and weighed 7 or 8 tons—but its fellow tyrannosaur Dilong, which lived over 60 million years earlier, tipped the scales at 25 pounds, an object lesson in how plus-sized creatures tend to evolve from wee ancestors. Even more remarkably, the eastern Asian Dilong was covered with feathers—a hint that even the A Dinosaur Called Tiny T. Rex may have sported plumage at some stage of its A Dinosaur Called Tiny cycle. When most people think of sauropodsthey picture huge, house- sized plant-eaters like Diplodocus and Apatosaurussome of which approached tons in weight and stretched 50 yards from head to tail. Europasaurusthough, wasn't much bigger than a modern ox, only about 10 feet long and less than 2, pounds. The explanation is that this late Jurassic dinosaur lived on a small island cut off from the European mainland, like its equally tiny titanosaur cousin Magyarosaurus. The three-pound Aquilops was a true outlier on the ceratopsian family tree: whereas most ancestral horned and frilled dinosaurs hailed from Asia, Aquilops was discovered in , in sediments dating to the middle Cretaceous period about million years ago. You wouldn't know to look at it, but the descendants of Aquilops, millions of years down the line, were multi-ton plant-eaters like Triceratops and that could successfully fend A Dinosaur Called Tiny an attack by a hungry T. You couldn't ask for a better name for a tiny dinosaur than Minmi —even if this early Cretaceous ankylosaur was named after Australia's Minmi Crossing and not the infamous "Mini-Me" from the "Austin Powers" movies. The pound Minmi may not seem especially small until you compare it to later, multi-ton ankylosaurs like Ankylosaurus and Euoplocephalus —and judging by the wee size of its brain cavity, it was every bit as dumb as or even dumber than its more famous descendants. The second example on this list of "insular dwarfism"—that is, the tendency of animals confined to island habitats to evolve to modest A Dinosaur Called Tiny pound Tethyshadros was a fraction of A Dinosaur Called Tiny size of most hadrosaursor duck-billed dinosaurs, which usually weighed two or three tons. On an unrelated note, Tethyshadros is only the second dinosaur ever to be discovered in modern-day Italy, much of which was submerged under the Tethys Sea during the late Cretaceous period. Since many ornithopods —the two-legged, plant-eating dinosaurs ancestral to hadrosaurs— were slight in stature, it can be a tricky matter to identify the smallest member of A Dinosaur Called Tiny breed. But a good candidate would be the pound Gasparinisauraone of the few ornithopods to have lived in South America, where either scant plant life or the exigencies of predator- prey relationships downscaled its body plan. By the way, Gasparinisaura is also one of the few dinosaurs to be named after the female of the species. Because it was restricted to an island habitat, though, Magyarosaurus weighed only a single ton. Some paleontologists believe this titanosaur plunged its neck under the surface of swamps and fed on aquatic vegetation! In February ofpaleontologists in China discovered the type fossil of Nemicolopterusthe tiniest flying reptile yet identified, with a wingspan of only 10 inches and a weight of a few ounces. A Dinosaur Called Tiny enough, this pigeon-sized pterosaur may have occupied the same branch of evolution that gave rise to the enormous Quetzalcoatlus 50 million years later. A few million years after the - —the deadliest mass extinction in the history of life on earth—marine life had yet to fully recover. You wouldn't have known to look at it, but the descendants of Cartorhynchus, millions of years down the line, included the enormous, ton ichthyosaur Shonisaurus. Crocodiles —which evolved from the same archosaurs that spawned the dinosaurs—were thick on the ground during the Mesozoic Era, making it difficult to identify the smallest member of the breed. But a good candidate would be Bernissartiaan early Cretaceous crocodile about the size of a house cat. As tiny as it was, Bernissartia sported all the classic crocodilian features narrow snout, knobby armor, etc. Sharks have a deep evolutionary history, predating mammals, dinosaurs, and pretty much all terrestrial vertebrates. To date, the smallest identified prehistoric shark is Falcatusa tiny, bug-eyed menace the males of which were equipped with sharp spines jutting out A Dinosaur Called Tiny their heads which seem to have A Dinosaur Called Tiny used, rather painfully, for mating purposes. Needless to say, Falcatus was a far cry from true undersea A Dinosaur Called Tiny like Megalodonwhich it preceded by a whopping million years. Believe it or not, shortly after they evolved hundreds of millions of years ago, amphibians were the largest land-dwelling animals on earth—until their pride of place was usurped by even bigger prehistoric reptiles. One of the smallest amphibians yet identified, a mere tadpole compared to giants like Mastodonsauruswas Triadobatrachusthe "triple frog," which inhabited the swamps A Dinosaur Called Tiny Madagascar during the early Triassic period and likely lay at the root of the frog and toad evolutionary tree. Pound for pound, the birds of the Cretaceous period weren't any bigger than their modern counterparts for the simple reason that a dinosaur-sized pigeon would immediately plummet out of the sky. Even by this standard, though, Iberomesornis was unusually small, only about the size of a finch or sparrow—and you'd have to take a close look at A Dinosaur Called Tiny bird to discern its basal anatomy, including a single claw on each wing and a set of jagged teeth embedded in its tiny jaws. Not only was the early Jurassic Hadrocodium incredibly tiny—only about an inch long and two grams—but it's represented in the fossil record by a single, exquisitely preserved skull, which hints ironically at a bigger-than-usual brain compared to the size of its body. Just like some dinosaur species, many mammals developed in isolated circumstances during the Cenozoic Era. What we call the Dwarf Elephant included scaled-down, quarter-ton species of MammothsMastodons and modern elephants, all of which lived on various Mediterranean islands during the Pleistocene epoch. For every Australian behemoth like the Giant Wombat or the Giant Short-Faced Kangaroothere were a bewildering variety of tiny pouched mammals. While there's no consensus as to which was the smallest, one good possibility is the Pig-Footed Bandicoota long-nosed, spindly-legged, A Dinosaur Called Tiny furball that hopped across the plains of Australia until the modern era, when it was crowded out by the arrival of European settlers and their pets. The evolutionary lineage of modern canines goes back 40 million years, including both plus-sized breeds like Borophagus and the Dire Wolf and comparatively runty genera like Leptocyon, the "slender dog. As with many other animals on this list, it's not a straightforward matter to identify the smallest prehistoric primate : after all, the vast majority of Mesozoic and early Cenozoic mammals were mouse-sized.
