Epoch

Late Cretaceous

100.5000 – 66.0000 Ma

The Late Cretaceous is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after creta, the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period.

Today we will be looking at the small ceratopsian dinosaur, Leptoceratops gracilis!Leptoceratops was a plant-eating ceratopsian dinosaur that lived in what is now Alberta, Canada, during the late Cretaceous period, between 68 and 66 million years ago. From beak to tail it measured about 6.5 feet (about 2m) and would have been able to walk on four or two limbs when alive. The genus name translates to "small horned face".
