Why did they change Brontosaurus?

When scientists looked at these fossils later they realized that the Apatosaurus was the same animal as the Brontosaurus. Scientists use the first name given to an animal, so they decided to rename the Brontosaurus to Apatosaurus because Apatosaurus came first. Marsh thought they were different animals.

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.”

When was Brontosaurus renamed?

Dinosaur fossils that were originally described as Brontosaurus excelsus in 1879 and later renamed should indeed be classified as Brontosaurus, a study of dozens of dinosaur specimens concludes.

Did the Brontosaurus actually exist?

Brontosaurus was a large sauropod, a group of typically large dinosaurs with long necks and long tails. It lived during the Late Jurassic Period, from about 156 to 145 million years ago. The first recorded evidence of Brontosaurus was discovered in the 1870s in the USA.

What happened to the Brontosaurus?

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. The creature is still extinct, but it has now been re-classified as a dinosaur after being sent into exile by the scientific community.

What did Brontosaurus evolve into?

Apatosaurus, being the first named, took precedence, and Brontosaurus was no more. Instead, the dinosaur species once known as B. excelsus became A. excelsus.

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.

Why did the Brachiosaurus go extinct?

A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs. Food chain imbalances lead to the starvation of the dinosaurs.

Are Brachiosaurus and Brontosaurus the same?

The key difference between Brontosaurus and Brachiosaurus is the appearance of them. Brontosaurus is an elephant-like dinosaur while Brachiosaurus is a giraffe-like dinosaur. Furthermore, Brontosaurus is one of the longest dinosaurs while Brachiosaurus is one of the tallest dinosaurs that lived on Earth.

Is Brontosaurus a real dinosaur?

If you grew up loving Brontosaurus only to be told it wasn’t a real dinosaur, it’s time to rejoice: the gentle giant may have received a new lease on life. The giant sauropod, long thought to be an Apatosaurus that someone got wrong, was actually its own type of dinosaur all along, scientists say Tuesday in PeerJ.

Who discovered the Brontosaurus and Apatosaurus?

The story starts 130 years ago, in a time known as the “Bone Wars.” Apatosaurus (right, opposite a Diplodocus skeleton at the Carnegie Museum of Natural History in Pittsburgh), is what paleontologist Othniel Charles Marsh actually found when he thought he’d discovered the Brontosaurus.

What happened to the Brontosaurus head?

That Brontosaurus finally met its end in the 1970s when two Carnegie researchers took a second look at the controversy. They determined a skull found in a quarry in Utah in 1910 was the true Apatosaurus skull. In 1979 the correct head was placed atop the museum’s skeleton.

Why is the Brontosaurus called the thunder lizard?

The Brontosaurus was gone at last, but Lamanna suggests the name stuck in part because it was given at a time when the Bone Wars fueled intense public interest in the discovery of new dinosaurs. And, he says, it’s just a better name. “Brontosaurus means ‘thunder lizard,'” he says.
