An article published in the journal “PLOS One” describes a research on Sarahsaurus aurifontanalis, a relatively small dinosaur but part of the clade of sauropodomorphs, the giant dinosaurs that include iconic species such as brontosaurus. Paleontologists Adam Marsh and Timothy Rowe of the University of Texas at Austin Jackson School of Geosciences studied the fossils of this dinosaur that lived about 185 million years ago analyzing migrations and diversifications within its clade.
