Cretaceous-Paleogene Extinction: Meteorite hitting the Earth. #kpgextinction

End-Triassic Extinction: Pangaea split by a line of fire to show the future mid-oceanic ridge massively erupting as the supercontinent breaks up.

May: The last #Edmontosaurus. This idea came to me after reading Riley Black’s The Last Days of the Dinosaurs. The idea is that during the shockwaves caused by the meteorite’s impact, an Edmontosaurus egg got buried and survived the ensuing global firestorm underground. After hatching, she emerges into a devastated world. #myArt #paleoart #kpgextinction #dinosaur
