[ Watch the Video: Scientists Name New Species of Dinosaur ] Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in the journal Nature Communications have identified a new species of dog-sized bone-headed (pachycephalosaur) dinosaur. The team was able to identify the new dinosaur species using both recently discovered and historically collected fossils. The dinosaur, Acrotholus audeti, represents the oldest bone-headed dinosaur in North America, and possibly the...

Researchers, studying the heads of modern animals and one of the world's best dinosaur fossils (Stegoceras), have found that the bony anatomy of the dinosaur skull was better at protecting the brain than in any modern head-butter. Scans and computer modeling suggest that the pachycephalosaur domes of Stegoceras -- a small, two-legged dinosaur that browsed leaves and berries in forests of the Late Cretaceous -- were built to fend off rivals by delivering vicious head butts. Results of the...

Tyrannosaurus rex was an opportunistic feeder, not a top predator, paleontologists say The ferocious Tyrannosaurus rex has been depicted as the top dog of the Cretaceous, ruthlessly stalking herds of duck-billed dinosaurs and claiming the role of apex predator, much as the lion reigns supreme in the African veld. But a new census of all dinosaur skeletons unearthed over a large area of eastern Montana shows that Tyrannosaurus was too numerous to have subsisted solely on the dinosaurs it...

Named dinosaurs may actually be juvenile or subadults of already known taxa Paleontologists from the University of California, Berkeley, and the Museum of the Rockies have wiped out two species of dome-headed dinosaur, one of them named three years ago "“ with great fanfare "“ after Hogwarts, the school attended by Harry Potter. Their demise comes after a three-horned dinosaur, Torosaurus, was assigned to the dustbin of history last month at the Society of Vertebrate Paleontology...

After half a century of debate, a University of Alberta researcher has confirmed that dome-headed dinosaurs called pachycephalosaurs could collide with each other during courtship combat. Eric Snively, an Alberta Ingenuity fellow at the U of A, used computer software to smash the sheep-sized dinosaurs together in a virtual collision and results showed that their bony domes could emerge unscathed.The computer simulations by Snively and his co-author Andrew Cox of Villanova University offer...

INDIANAPOLIS (AP) - The 66-million-year-old skull of a dinosaur whose name was inspired by the Harry Potter series has found a permanent home in the Children's Museum of Indianapolis. Dracorex hogwartsia will be housed permanently at the museum, officials and paleontologist Robert Bakker were to announce Monday. The dinosaur's name was taken from the Latin words for dragon and king, and the fictional Hogwarts School for Witchcraft and Wizardry in J.K. Rowling's Harry Potter novels. Rowling...

INDIANAPOLIS -- The Children's Museum of Indianapolis, along with a world-renowned team led by paleontologist Dr. Robert Bakker, today announced the discovery and acquisition of a 66-million-year-old dinosaur skull that represents a new dinosaur species. The first-of-its-kind discovery in North America is an unexpected flat-headed dinosaur from the pachycepahlosaur family - plant-eating dinosaurs that were about the size of a horse. This fossil, found in central South Dakota, made its debut...

Troodon, meaning “wounding tooth,” is a genus of bird-like dinosaur from the Late Cretaceous Period (76 to 65 million years ago). Troodon was discovered in 1855 in North America and was one of the first dinosaurs found there. Fossils of this specimen have been found from Alaska to Wyoming, with possible Troodon fossils also being found in Texas and New Mexico. Troodon is known from the Judith River Formation and the upper Two Medicine Formation of Montana, the Judith River Group of...

Alaskacephale is a genus of dinosaur from the late Campanian stage of the Late Cretaceous Period (80 to 70 million years ago). It was first described by Roland Gangloff and colleagues as an unnamed pachycephalosaurid, possibly a Pachycephalosaurus, but after further studies it was determined to have dissimilar characteristics. It was given the name Alaskacephale by Robert Sullivan in 2006. The name Alaskacephale refers to Alaska, where the fossil was found. The species name anglophile,...

Homalocephale, meaning "even head", is a genus of dinosaur from the Late Cretaceous Period. It lived in what is now Mongolia, more than 80 million years ago. It was described in 1974 and consists of a single species. The type species is H. calathocercos. This 10 foot long herbivore had a flat, wedge-shaped skull, hence its name. The reason for the thick flat skull is believed to be for males that competed in head-butting rituals, similar to that of modern-day iguanas. The pelvis is broad,...

It was formally described by Bob Bakker and Robert Sullivan in 2006. The species name hogwartsia was inspired by the Harry Potter series of books by J.K....
