Rafinesquina, seen in this close-up shot, was an ancient genus of brachiopod belonging to order Strophomenida.

Over approximately 2.5 million years, North America likely hosted 2.5 billion Tyrannosaurus rexes, a minuscule proportion of which have been dug up and studied by paleontologists, according to a UC Berkeley study. (Image by Julius Csotonyi, courtesy of Science magazine)

How many T. rexes were there? Billions
