All About Dinosaurs And The Olden Days
by: Alayna B., Grade: 4


Triassic Triassic dinosaurs were along time ago!!! People think that Triassic dinosaurs, were about 250 million years ago!! Way back in that time, the dinosaur were meat eaters. Triassic dinosaurs were littler than the, Jurassic, and, Cretaceous. These small animals actually were fast moving reptiles. The Triassic walked on their hind legs. Remember when I told you that the, Triassic dinosaur ate meat but one. The Pro-sauropods were 20 foot long plant eaters! A couple of million of years ago became, Jurassic dinosaur. Jurassic dinosaur began over 200 million years ago! These dinosaurs were meat eaters like Triassic dinosaurs. These dinosaurs were bigger and heavier. Dinosaurs these days walked on their 4 legs and were a little slower than the Triassic dinosaurs. Mammals and reptiles were starting their lives when the dinosaurs were alive. This lasted about 145 years ago. WOW that was a really long time ago!!!!! Cretaceous The Cretaceous dinosaurs were about 145 million years ago! New dinosaurs had been coming into the dinosaur land! Horned dinosaurs and duckbills. Raptors were also alive when the Cretaceous were alive. ( raptors have super duper very sharp teeth). The Cretaceous began to die 65 million years ago!! I hope you liked my story about dinosaurs bye!
