Dinosaur with protrusion from back of head

Newly discovered dino with skull protrusion like "decorative fins on classic s cars" gets a name like a god and a car.

Of all the dinosaurs, this one had the best chance of being a radio star. Called the Parasaurolophus, it was a duck-billed plant eater about the size of a pickup truck that had a unique characteristic — a large crest jutting from the back of its head that served as a horn. As part of the summer-long series Backyard Dinosaurs — which will feature a different dinosaur found in Alberta each week — University of Alberta paleontologist Scott Persons explained to the Homestretch how scientists came to that conclusion, and were even able to reproduce the sound it may have made. For our first backyard dinosaur, I want to talk about a critter called Parasaurolophus. It's a kind of duckbill or hadrosaur.

They had large head crests they used for trumpeting.

Small size; bipedal posture; thickened skull. Small size; bipedal posture; horned snout. Hongshanosaurus was very similar to Psittacosaurus without actually being a species of Psittacosaurus: this early Cretaceous ceratopsian horned, frilled dinosaur was distinguished from its more famous contemporary only by the distinctive shape of its skull.

Ceratopsians came in many shapes and sizes. Ceratopsians— the horned, frilled dinosaurs—were some of the most common plant-eaters of the later Mesozoic Era. Explore pictures and detailed profiles of over 60 ceratopsian dinosaurs, ranging from A Achelousaurus to Z Zuniceratops. Woodlands of North America. Historical Period:. Late Cretaceous million years ago. Size and Weight:.

The Evolution and Behavior of Pachycephalosaur Dinosaurs. Pachycephalosaurs Greek for "thick-headed lizards" were an unusually small family of dinosaurs with an unusually high entertainment value. As you can guess from their name, these two-legged herbivores were distinguished by their skulls, which ranged from the mildly thick in early genera like Wannanosaurus to the truly dense in later genera like Stegoceras. Some later pachycephalosaurs sported almost a foot of solid, albeit slightly porous, bone on top of their heads! See a gallery of bone-headed dinosaur pictures and profiles. However, it's important to understand that big heads, in this case, didn't translate into equally big brains. Pachycephalosaurs were about as bright as the other plant-eating dinosaurs of the late Cretaceous period which is a polite way of saying "not very" ; their closest relatives, the ceratopsians , or horned, frilled dinosaurs, weren't exactly nature's A students, either. So of all the possible reasons pachycephalosaurs evolved such thick skulls, protecting their extra-big brains certainly wasn't one of them.

Aralosaurus Canardia? It has been noted that morphological differences between Stygimoloch and Pachycephalosaurus may also partly be due to slight stratigraphic differences. Other hadrosaurids had large heads without needing large hollow crests to serve as attachment points for supporting ligaments. Foraminacephale brevis. Jaxartosaurus Kazaklambia Latirhinus? A curious exception to this rule is the ceratopsians horned, frilled dinosaurs , which have yielded extensive fossil remains in North America but virtually nothing in China dating to the last half of the Cretaceous period. Measure advertising performance. Sandia National Laboratories December 5, And second, Yamaceratops prospered tens of millions of years before its more famous descendants, during the middle rather than the late Cretaceous period. A good example is Eotriceratops, which the average person would find virtually indistinguishable from Triceratops but which merits its own name thanks to some obscure anatomical features for example, the shape of its jugal horn, epoccipitals, and premaxilla. PLOS Biology. Retrieved December 4, By the way, for over a decade the type fossil of Aquilops was identified as Zephyrosaurus, a non-ceratopsian ornithopod, until a re-examination of the remains prompted this new assessment. Currie Dinosaur Museum.

While scientists proposed a second species in the genus, P. Since these dinosaurs are known primarily from their skulls, many aspects of their appearance and behavior remain unknown.

Like a horn on Triceratops? Sinocephale bexelli. Currie Dinosaur Museum. Camptosaurus Draconyx Oblitosaurus Owenodon Riabininohadros. Retrieved Specifically, its contemporaries were the ceratopsian Pentaceratops sternbergii ; [8] the pachycephalosaur Stegoceras novomexicanum ; [49] and some unidentified fossils belonging to Tyrannosauridae ,? Most likely, Styracosaurus males with more elaborate frills were more attractive to the females of the genus. Zanno, L. Unfortunately, pending additional fossil discoveries, there's not much else we can say about Albalophosaurus or its exact relationship to the early ceratopsians of the Asian mainland. Jasinski, S. What set this genus apart from more famous relatives like Triceratops were the paired, forward-curving horns set above its eyes, which reached a whopping four feet in length; in fact, Coahuilaceratops is the longest-horned dinosaur yet discovered. If intimidation failed, the Pachycephalosaurus would bend its head downward and to the side, striking the rival on its flank.
