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.
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.
