Why is a Brontosaurus not really a dinosaur?

Brontosaurus has a colorful history. Named by O.C. Marsh in the 1880s, the dinosaur was identified in 1903 as a member of the Apatosaurus genus, which Marsh had found a few years earlier. So the “thunder lizard” was condemned to the realm of the scientifically invalid, becoming the dinosaur that “never even existed.”

What dinosaur did not actually exist?

Brontosaurus
Brontosaurus, whose name means “Thunder Lizard,” is not an actual dinosaur. It is actually a mix of Apatosaurus, meaning “Deceptive Lizard,” and Camarasaurus, meaning “Chambered Lizard,” due to the hastiness of paleontologist Othniel Charles Marsh.

Was the Brachiosaurus a real dinosaur?

Brachiosaurus was an unusual dinosaur that lived 155.7 million to 150.8 million years ago during the mid- to late Jurassic Period. Specimens have been found primarily in the fossil-rich Morrison Formation in North America, but the dinosaur did not resemble any of the others that roamed the region.

Is the Brontosaurus 2020 real?

The Brontosaurus, known fondly as one of the largest creatures to have ever walked the planet while having had one of the smallest brains of all the dinosaurs, is back.

What is a Brontosaurus called now?

Apatosaurus
Scientists use the first name given to an animal, so they decided to rename the Brontosaurus to Apatosaurus because Apatosaurus came first. Scientists now know that the back bones of the Apatosaurus grew together as the animal gets bigger.
