Recent actions by the Trump administration — a wave of unprecedentedly large family separations at the border, aggressive trade-war-fueling tariffs and rebukes of allies — have made some feel as though the Barack Obama presidency was an unrecognizable era shrouded in an ancient past.

Perhaps, then, it is fitting that the fossil of a disc-shaped animal that lived about 550 million years ago has been christened with the name Obamus coronatus. The name is complete with a Latin word meaning “crowned” for the wreath-like modules found imprinted on a lush seafloor that is now an arid, mountainous desert.
