brontosaurus

In Depth The turbulent history of Brontosaurus        For well over one hundred years there was a great question asked amongst dinosaur enthusiasts‭; ‬is Brontosaurus actually Apatosaurus‭?‬ Well this all began in a period of American paleontological history dubbed the‭ ‘‬bone wars‭’‬,‭ ‬a fierce rivalry between two men named Edward Drinker Cope and Othniel Charles Marsh.‭ … Read more

Struthiomimus

Intro of Struthiomimus        Struthiomimus remains were actually known all the way back to‭ ‬1901,‭ ‬but were interpreted by Lawrence Lambe to belong to Ornithomimus altus,‭ ‬the first ornithomimid to be named.‭ ‬In‭ ‬1917‭ ‬however,‭ ‬Henry Fairfield Osborn‭ (‬the man who is perhaps best remembered for naming Tyrannosaurus‭) ‬identified key differences in the bones,‭ ‬especially the … Read more
