How tall was the average Brontosaurus?

Apatosaurus/Brontosaurus was one of the largest land animals that ever existed. The dinosaur Brontosaurus is now called Apatosaurus. This enormous plant-eater measured about 70-90 feet (21-27 m) long and about 15 feet (4.6 m) tall at the hips. It weighed roughly 33-38 tons (30-35 tonnes).

How long was a Brontosaurus neck?

The necks of the sauropod dinosaurs reached 15 m in length: six times longer than that of the world record giraffe and five times longer than those of all other terrestrial animals.

How long did a Brontosaurus live?

Othniel Charles Marsh found the first Brontosaurus bones in Wyoming in the 1870s. The Brontosaurus may have had a lifespan as long as 100 years. The eggs of the Brontosaurus are believed to have been about a foot long. It is believed the young Brontosaurus’ took roughly ten years to reach their full size.

How long ago was the Brontosaurus?

about 156 to 145 million years ago
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.

How fast can a Brontosaurus run?

12 – 19 mph
Brontosaurus/Speed

Trackways of sauropods like Brontosaurus show that the average range for them was around 20–40 km (10–25 mi) per day, and they could potentially reach a top speed of 20–30 km/h (12–19 mph).

How many brains does a Brontosaurus have?

As paleontologists now know, no dinosaur had a second brain. There are two intertwined issues here. The first is that many dinosaurs had noticeable expansions of their spinal cords around their limbs–a feature that left its mark in the size of the neural canal in the vertebrae.

Why were Brachiosaurus necks so long?

The plant-eating sauropod dinosaurs, such as the brachiosaurus and Apatosaurus (formerly called the brontosaur), were the largest animals ever to walk on Earth. And just like giraffes, some scientists think the brachiosaur raised up its neck to browse for vegetation in tall trees.

Which dinosaur has the longest neck?

To date, the longest neck in relation to its body belongs to the Erketu ellisoni, a sauropod with a neck more than 24 feet (8 meters) long. It lived in what is now Mongolia’s Gobi Desert about 120 to 100 million years ago.

Which dinosaur survived the longest?

The longest living dinosaurs were dinosaurs such as Apatosaurus, Brachiosaurus, Supersaurus, etc (these are called sauropods) and were long-necked plant eaters. They could live up to 100 years!

How long did T Rex live?

Tyrannosaurus rex had a life expectancy of about 28 years. Previous studies have suggested that it went through a growth spurt in its teenage years, but until recently, scientists didn’t know much about how it grew from a hatchling to a powerful predator.

What was the life expectancy of a Tyrannosaurus rex?

28 years
These studies, done in conjunction with paleontologists at AMNH, document that that Tyrannosaurus, which attained a weight of more than 10,000 pounds as an adult, reached sexual maturity at about 20 years of age and lived for up to 28 years.

How did the brontosaurus go extinct?

Both of these theories hold ground due to the fact that the Apatosaurus (Brontosaurus) was so large it could not efficiently move through forests to feed on masses of vegetation, nor could it stand in swampy ground without sinking and thereby meeting a slow death.
