End times

Caption

Deposits in Morocco associated with the Triassic-Jurassic mass extinction, 201.6 million years ago. Red sediments in many locations around the world contain Triassic-era fossils. The white band on top of them is where the sediments were altered by massive volcanism, as evidenced by the gray/black basalt layers topping the assemblage.
