He noticed
that a group of fossil reptiles, including Megalosaurus,
Iguanadon and Hylaeosaurus, all had five vertebrae
that were fused to their pelvic girdles and had
column-like legs instead of the sprawling legs
that other reptiles have. He said that all these
fossils belonged to a class which he named “dinosaurian” from
the words “deinos” meaning “terrible” and “sauria” meaning “Lizard.”
Richard Owen was later a fierce opponent of Darwin and Gideon Mantell. He did
not believe in evolution; his papers on dinosaurs were published partly in an
attempt to forestall early ideas about evolution, which he thought were ungodly.
Ironically, his work actually helped support the evolutionists arguments.
