Period Land Animals The scale begins at the beginning of the middle Triassic period, 247 million years ago (mya). This is just before the first dinosaur, Nyasasaurus, appeared about 243 mya. The other side of the scale is the K-T boundary, the end of the Cretaceous period 66 mya when the dinosaurs (and many other species) became extinct. Dinosaurs – literally, the ‘terrible lizards‘ – were first recognized by science, and named by Sir Richard Owen (who preferred the translation ‘fearfully great’), in the 1840’s.
