Apatosaurus (Brontosaurus)

144-163 million years ago during the late Jurassic period

Apatosaurus who was also known as Brontosaurus has left this Earth, may he rest in peace. Apatosaurus was a sauropod or “lizard hipped” dinosaur and he lived 144-163 million years ago in the late Jurassic period. Apatosaurus lived in North America. He was classified as a member of the Diplodocidae dinosaur family, which contains dinosaurs with extremely long necks and tails. When fossil remains of Apatosaurus were being analyzed, there was a mix-up with fossils from a different dinosaur. Apatosaurus's original fossils had the head of a different dinosaur. When his more complete fossils were found, they were called Brontosaurus. Scientists later figured out their mix-up with poor Apatosaurus's fossils, and named the complete dinosaur Apatosaurus. It was later proved that the Brontosaurus fossils were actually that of Apatosaurus. Apatosaurus is still sometimes incorrectly known as Brontosaurus.
Since the day Apatosaurus hatched from his egg, he was a special dinosaur. He had an exceptionally long neck and tail. He was named Apatosaurus, which means “deceptive lizard” because his tail was very long and lizard shaped. It is unlike other dinosaur tails. Apatosaurus was never lonely, as he traveled in a herd of other Apatosaurus dinosaurs. Throughout his childhood and into adulthood, Apatosaurus grew extremely large. He grew to an amazing nineteen feet tall, seventy feet in length, fifteen feet wide at the hips, and he weighed thirty to thirty six tons. Apatosaurus was believed to be one of the largest land animals to have ever roamed the Earth, which was one of his best characteristics.

Despite Apatosaurus’s large size, he didn’t eat other animals. He was an herbivorous dinosaur, meaning that he only ate plants. His long neck was adapted for foraging even the tallest trees. His diet consisted of twigs, and needles of sequoia, fir, and pine trees. He probably also ate plants low to the ground. To help digest his food, Apatosaurus swallowed stones to grind the food in his stomach. Apatosaurus lived in southwest North America, so the climate was mostly mild. Also, he lived near trees and other plants, as that was what he ate.

Apatosaurus will forever be remembered for his accomplishments; he was one of the largest animals to ever roam the planet, he was kind to other animals (by eating only plants) and he was socially accepted, because he traveled in herds. Apatosaurus’s cause of death is unknown. One of his closest relatives, Supersaurus had also died around the same time as Apatosaurus. Also, some of his other relatives, which were dinosaurs classified in the Diplodocidae family had died. May they all rest in peace.
Apatosaurus is believed to have been one of the largest animals to have ever roamed the Earth. Above, he is compared to the size of the average man, woman, and car.
