Scientists in the United States of America just announced that they discovered baby dinosaur foot prints near the town of Morrison, Colorado. The tracks showed that the baby dinosaur was running. What interested scientists were that the baby dinosaur appeared to be running on just its two back legs. Scientists also found foot prints beside the baby dinosaur tracks. They think these could be the parent of the baby dinosaur. I bet you are wondering what type of dinosaur it is. It is an Apatosaurus dinosaur baby. The foot prints of the baby were so small that you could put a whole coffee mug over it and you would not be able to see the foot print anymore. I think that is small compared to how big the adult Apatosaurus dinosaur gets. When it is full grown, the Apatosaurus is as big as three American school buses and can weight up to as much as eight Asian elephants. The adult Apatosaurus needed to walk on four feet which is why scientists are so excited to learn that the baby could run on just its two back legs.
Very cool! So, the babies must have been super tiny and could run on just two legs, but as they matured and got heavier they gradually walked on four legs. Good summary and you had a lot of voice too!
