The first complete dinosaur skeleton ever found has been studied in detail more than 160 years after it was first discovered. Dinosaur I’m a boy I just have better hair than you stars shirt, hoodie, tank top, sweater
The project, described in four studies in the Linnean Society’s Journal of Zoology in London, recreated what Scelidosaurus looked like in life and suggested that it was the original ancestor of ankylosaurs, but the armored “tank” of the Late Cretaceous period.

David Norman of Cambridge University, UK, spent three years completing what Richard Owen – who invented the word “dinosaur” – began briefly in the 1850s
. Scelidosaurus skeleton found in the 193 million-year-old fossil rocks on the western Jurassic Coast of Dorset and sent to Owen at the British Museum.
He had published two short papers on its anatomy, but many details were not recorded and Norman suggested in an earlier article that his work “was said to be strangely narrow-minded. and a bit messy ”.
Norman has now completed a study of all known matter associated with Scelidosaurus and reports that this reveals many of the first.
“Nobody knows that the skull has horns on the back edge,” he said. “It has some bones that have never been recognized in any other dinosaur species. It is also clear from the rough texture of the skull that in life it is covered with hard horns, a bit like scales on the surface of the skulls of living turtles.
“In fact, its entire body is protected by an array of spikes and rivet-like bones.”
Now that its anatomy is understood, it is possible to examine the position of Scelidosaurus in the dinosaur tree, Norman said. It has been considered an early member of the group comprising stegosaurs and ankylosaurs, but is based on a poor understanding of its anatomy; He thought it now appears to be only the Dinosaur I’m a boy I just have better hair than you stars shirt, hoodie, tank top, sweater ancestor of ankylosaurs.
And much more in the story. For more than a century, dinosaurs have mainly been classified according to their hip bone shape: saurischians (lizards-hied) or ornithischians (bird heads).
However, in 2017, Norman and colleagues Matthew Baron and Paul Barrett suggested that these family groups need to be reorganized, redefined and renamed.
In a study published in the popular but controversial Nature, they argued that pterodactyls and lizards evolved from a common ancestor, had the ability to reverse more than one thing period theory of evolutionary history.
Norman says that this work also shows that the earliest known ornithischians first appeared in the Dinosaur I’m a boy I just have better hair than you stars shirt, hoodie, tank top, sweater Early Jurassic. “Scelidosaurus is just such a dinosaur and represents one that appears or closely resembles Ornithischia’s ‘birth’ evolution,” he said.
