Technically, Ankylosaurus (Greek for "fused lizard" or "stiffened lizard") should be pronounced with the accent on the second syllable: ank-EYE-low-SORE-us. ©, 2019. The ankylosaurus existed in the Cretaceous period which was about 65.5 million to 66.8 million years ago. Huge plates of bone were embedded into the skin which helped protect the Ankylosaurus against attackers. The Ankylosaurus shield was made of deeply embedded bone plates covered with a thick layer of keratin, a protein contained in human hair, bird's beaks and rhinoceros horns. On the following slides, you'll discover 10 fascinating Ankylosaurus facts. The lack of ankylosaurus remains that have been discovered point to the fact that they were very rare. The dinosaur was covered with a thick armor on its skin which consisted of oval plates of bone and massive knobs referred to as scutes and osteoderms respectively. This is from a specimen collected in Custer County, Montana. , Science Kids ©  |  Home  |  About  |  Topics  |  Experiments  |  Games  |  Facts  |  Quizzes  |  Projects  |  Lessons  |  Images  |  Videos  |  Privacy  |  Sitemap  |  Updated: Apr 11, 2020. 10 Facts About Ankylosaurus. The remains of this smaller ankylosaur abound so much that we know that even its eyelids were covered by bony plates. Even a desperately hungry Tyrannosaurus Rex (which weighed more than twice as much) would have found it nearly impossible to tip over a full-grown Ankylosaurus and take a bite out of its soft belly--which is why late Cretaceous theropods preferred to prey on less-well-defended Ankylosaurus hatchlings and juveniles. This armor was made up of densely packed osteoderms, or "scutes," deeply embedded plates of bone (which weren't directly connected to the rest of Ankylosaurus' skeleton) covered by a thick layer of keratin, the same protein as is contained in human hair and rhinoceros horns.

The head was somewhat flattened with the front jaws being modified to a beak, and the remaining part of the jaws is made of rows of leaf-shaped teeth. Ankylosaurus was one of the largest ankylosaurs, with a total length of about 10 metres (33 feet) and a probable weight of about four tons. We are the world's largest online educational resource dedicated to dinosaurs, paleontology, prehistoric animals and everything related to it. Ankylosaurus lived between about 74 and 65 million years ago (possibly 68 to 66 million years ago) towards the end of what scientists call the Cretaceous Period.Scientists subdivide geological Periods into stages, and the stage of Late Cretaceous Period in which Ankylosaurus lived is known as the Maastrichtian stage. Ankylosaurus is one of the most recognizable dinosaurs and also one of the best known to the general public because of its unique appearance: often nicknamed the Cretaceous sherman tank, this beast had a thick, almost impenetrable armor of osteoderms that protected its head, its neck, its back and even its tail. He also discovered the tail club. During the late Cretaceous period, 65 million years ago, the western United States enjoyed a warm, humid, near-tropical climate. Brown went on to unearth numerous other Ankylosaurus remains, including scattered pieces of fossilized armor that he initially attributed to a dinosaur he dubbed "Dynamosaurus" (a name that has unfortunately vanished from the paleontological archives). Ankylosaurus has lent its name to a widespread family of armored, small-brained, plant-eating dinosaurs, the ankylosaurs, which have been discovered on every continent except Africa. Osteoderm of Ankylosaurus specimen AMNH 5895 in outer and inner view. There were two rows of spike along the body of ankylosaurus. It could be because of their low population or high tendency of preying by other bigger dinosaurs. 5. The evolutionary relationships of these armored dinosaurs is a matter of dispute, beyond the fact that ankylosaurs were closely related to stegosaurs; it's possible that at least some of their surface similarities can be chalked up to convergent evolution. You can read more about it, The Marine Reptiles of The Late Cretaceous, Its armor was similar to that of a modern crocodile, Godzilla’s nemesis Anguirus is based on Ankylosaurus, Fossils of this dinosaur have been found in Canada and Montana, Its armor made it almost impossible to be preyed upon. It was first discovered in 1908 by Barnum Brown. The Ankylosaurus was a big dinosaur that featured huge plates of body armor to protect itself from attackers, and if that wasn’t enough it also had a massive tail club that was strong enough to break bones. The ankylosaurus fed on low lying plants and grassy pastures. It is also possible that they have been used as a resonance chamber, helping the animal to make distress calls or during mating. Check out our cool Ankylosaurus facts for kids and have fun learning more about this amazing dinosaur. Ankylosaurus were herbivores (plant eaters) and had small teeth relative to their body size. All of his findings are currently showcased in New York’s American Museum of Natural History. The Ankylosaurus was a big dinosaur that featured huge plates of body armor to protect itself from attackers, and if that wasn’t enough it also had a massive tail club that was strong enough to break bones. Like its close relative, Ankylosaurus had a complex system of channels inside its skull. The name Ankylosaurus means ‘fused lizard’. The tail of the Ankylosaurus was strong enough even to shatter the bones of a Tyrannosaurus Rex while fighting (which is comparable to the strong tail of the modern-day kangaroo that is able to give severe injuries to an attacking lion). It was named Ankylosaurus—a name which means “fused lizard”. However, these archaeological remains were enough to deliver reliable data about the physical features of the entire creature. The meaning of the word ‘Ankylosaurus’ (also its genus name) means “fused lizard” (which is derived from the animal’s fused osteoderms), while ‘magniventris’ (its specific name) means “great belly”. It was the last non-avian dinosaur to ever exist. DINO WORLD ©2020 | FRENCH. The name Ankylosaurus, or "fused lizard," was granted in 1908 by the famous paleontologist and fur coat enthusiast Barnum Brown, two years after unearthing the holotype specimen in the Hell Creek formation in Montana. However, he thought that these belonged to another dinosaur type. Published on July 2nd 2018 by admin under Reptiles. Their nasal passage was complex and was not only for scent purposes. Although the Ankylosaurus was a well armored creature, it was also quite slow. The signature feature of Ankylosaurus was its body armor. Shares. 4. Facts About Ankylosaurus, the Armored Dinosaur, Bob Strauss is a science writer and the author of several books, including "The Big Book of What, How and Why" and "A Field Guide to the Dinosaurs of North America. June 3, 2014 . Much like the stegosaurus, the osteoderms covering their skin was bite-proof to even the strongest of carnivores, providing their owner enough protection of the internal organs against its enemies. Computer models suggest that these creatures could only move about 6 miles per hour, which is just slightly faster than a turtle traveling at top speed. google_ad_client = "pub-4643150179421087"; google_ad_client = "pub-4643150179421087";
