While there is something to be said for not reconstructing dinosaurs as giant lizards, they didn't have mammalian postures either. was the world's first dinosaur — not the first to evolve, but the first to be formally described.

Clockwise from top left: Microraptor gui (a winged theropod), Apatosaurus louisae (a giant sauropod), Edmontosaurus regalis (a duck-billed ornithopod), Triceratops horridus (a horned ceratopsian), Stegosaurus stenops (a plated stegosaur), Pinacosaurus grangeri (an armored ankylosaur) Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic period.

The current official holder of the heavyweight title, Argentinosaurus, is thought to have weighed about 70 tons.

A refurbishment project undertaken between 20 prettied them up, and they were then listed as buildings of architectural/historical interest. Yet Hawkins's "lizards" — like the reconstructions — have more of a mammalian pose, standing on four sturdy legs. Owen may have employed the same philosophy here that drove his thoughts on dinosaur articulation.

Elaborate display structures such as horns or crests are common to all dinosaur groups, and some extinct groups developed skeletal modifications such as bony armor and spines.

(Natural News) A recent archaeological discovery that throws a wrench into the conventional theory of evolution has reportedly cost a California professor his job.

Mark Armitage, a former scientist at California State University, Northridge (CSUN), was reportedly fired after claiming to have unearthed a dinosaur fossil that still contains soft, flexible tissue, suggesting that it can't be millions of years old.

A 30-year veteran in his field, Armitage has published many studies over the years in peer-reviewed journals.
