Today we are looking at some fun cartoony drawings. The first is an Allosaurus mommy with her chick. Yes, a baby Theropod dinosaur is called a chick. The modern animals in the crocodile family carry their babies in their mouth so we could infer that baby Theropod dinosaurs, like Allosaurus, may have also carried their babies gently in their mouth. Allosaurus was a dangerous dinosaur to be around, unless you were her chick. Theropod dinosaur eggs were found in Portugal and the babies were born with little teeth but clearly needed parental care. So Theropod dinos must have been caring parents. Other evidence indicates that Theoropod dinosaurs mated for life. So BOTH mommy and daddy took care of the chicks. By the way, the meat eating dinos are called Theropods. This would include dinos like T. rex, Velociraptor, and of course Allosaurus. Allosaursus was one of the top predators of the Jurassic Period. Notice that there is no grass. Grass had not evolved yet.

This second picture is of a young Sauropod dino with her friend, a young Pteranodon. This drawing is from the Cretaceous Period. There were Sauropods in both the Jurassic and Cretaceous Periods, but Pteranodon lived only in the Cretaceous Period. Also, Grass first appeared in the Cretaceous Period. So if there is grass in a dino drawing, it must be the late Cretaceous Period. There was also a lot of volcanic activity during the late Cretaceous Period. By the way, the Pteranodon was NOT a flying dinosaur. It was a flying reptile called a Pterosaur. Pterosaurs ate primarily fish, but probably were scavengers too. Some of the larger Pterosaurs may have hunted dino eggs and baby dinos when a nest was left unguarded.
