Rafinesquina, seen in this close-up shot, was an ancient genus of brachiopod belonging to order Strophomenida. This order survived two mass extinction events, but the second represented a ‘death sentence’ from which they were unable to recover diversity, persisting for another hundred million years as a ‘dead clade walking’ before their eventual extinction.

New insights into mass extinctions

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

A new look at evolution in the oceans

Adzebills, also close relatives of cave-rails, were large, flightless birds with big beaks that could have been used to prey on small animals or strip vegetation. Illustration courtesy of Nobu Tamura, CC BY 3.0

Younger Tyrannosaurus Rex bites were less ferocious than their adult counterparts

These fossil ammonites have lost their outer coating of shell, revealing the iridescent nacre beneath. Now extinct, ammonites were a group of marine mollusks that first appeared about 409 million years ago, persisting until the extinction event that wiped out the dinosaurs about 66 million years ago.
