im not shure but you could look up ' how many pounds are Brontosaurs?' then do the math on how big the canyon is then you will figure it out
brontosaurus
Aptosaurus was the Brontosaurus, it just got a new name.
The Brontosaur Weighed about 33 to 38 tons (30-35 tonnes). when it lived during the Late Jurassic period
its a dinosaour so it would be logical if it did (but as far as a avrage man know all of them is dead so the answer is: NO not any longer)
Brontosaurus, more accurately called Apatosaurus, was a sauropod. Like all huge sauropods, they walked on four legs.
Brontosaurus is an invalid name for Apatosaurus excelsus. Apatosaurus excelsus was 75 feet long, 15 feet tall to the highest point on the back, and weighed between 18 and 25 tons.
Apatosaurus walked on four sturdy legs, had a bulky body, and a very long, narrow tail. It also had a long but thick neck and a small head. They were herbivores. They were also huge at 75 feet in length and weighing in at 18 to 25 tons.
No Brontosaurs is not a known dinosaur. The name Brontosaurus was given when bones of a Apatosaurus and the skull of a Camarasaurus were mixed up. This mistake was quickly realised but for some reason the name seemed to stick. Mostly when people say Brontosaurus they actually mean Apatosaurus.
