You Say Apatosaurus, I Say Brontosaurus

The Brontosaurus has been renamed Apaptosaurus due to a decades old mistake in identifying remains. Smaller skeletons were called Brontosaurus but were recently discovered to be immature remains of Apaptosaurus. Hence the renaming.

The Apatosaurus (deceptive lizard) , formerly known as Brontosaurus (thunder lizard), belonged to a member of herbivore  dinosaur which walked on four legs, had long necks and long tails. They were victims of a war of sorts in the distant past.

Othniel Marsh found an almost complete skeleton and it was mounted in Yale’s Peabody Museum. The Apatosaurus did not chew it’s food but swallowed stones to help grind the food in it’s stomach and it’s nostrils were on top of it’s head. It was 70-90 feet long and stood 10-15 feet tall at the hips. It had a massive body of 33-38 tons which is why it was called a “thunder lizard”. It was one of the biggest of the cold-blooded dinosaurs of that time.

It lived 157-175 million years ago during the Jurassic Period and it’s remains have been found in Colorado, Oklahoma, Utah, Wyoming. The Apatosaurus reproduced by laying eggs which the female closely guarded. During the Jurassic Period, the steamy jungles provided plenty of food for the Apatosaurus. This resulted in the flourishing of the Apatosaurus and all sauropods as well, since they had to consume hundreds of pounds of leaves each day. But the advance of the Cretaceous Period, which brought about the cooling of the earth from it’s volcanic state, meant a decline in the food supply.

    They keep changing names and this old man might get confused.
