Jurassic Giants: The Dominant Dinosaurs That Ruled the Earth

The Jurassic period occurred just about halfway through the Mesozoic era. During this time, various carnivorous beasts and massive sauropods shared the planet with other creatures. Specific dinosaurs, such as the Allosaurus, Dilophosaurus, and Apatosaurus, are well-known creatures from the period. Discover the Jurassic giants, the dominant dinosaurs that ruled the Earth in this post!

Allosaurus

The Allosaurus was a theropod that lived during the Late Jurassic period. Like other sauropods, it walked on its back legs and had relatively short forelimbs equipped with sharp claws. This dinosaur was around 35 feet long and weighed about 1500kg.

Paleontologists hypothesize that this beast used the talons on its arms to grab prey, which it devoured with its serrated teeth. The Allosaurus likely preyed on weaker dinosaurs when hungry, such as Stegosaurs. It’s also likely that this prehistoric beast scavenged for deceased dinosaurs when it was hungry and wanted an easy meal.

Dilophosaurus

Dilophosaurus was another dominant dinosaur that ruled the Earth during the early Jurassic period. Like the Allosaurus, the Dilophosaurus was also a large theropod; however, the Dilophosaurus was smaller than the Allosaurus. Most Dilophosaurus were only 19-to-20 feet long and weighed approximately 400kg. These dinosaurs ruled over what is now Arizona in the United States of America.

Dino Fun Fact

Some images and movies depict a Dilophosaurus with a frill around its neck, but there is little evidence to substantiate this as scientific fact.

Apatosaurus

Interestingly, while many of the carnivores and apex predators were large, many of the real giants were sauropods. The Apatosaurus stands out as a Jurassic beast because it was one of the largest animals to live during this period. At a whopping 69 feet long and 16 feet tall, it’s no wonder many consider the Apatosaurus a giant. Like other sauropods, the Apatosaurus walked on all four legs and feasted on surrounding forest vegetation.

Dino Fun Fact

The Apatosaurus and Brontosaurus come from the same family tree and are so similar that many assumed they were the same dinosaur for a long time. After learning more about both fossils, most scientists conclude that the species were unique.

What About T-Rex?

Many of us first think of the fearsome T-rex when we hear the word “Jurassic,” largely because of book and film franchises such as Jurassic Park. However, the Tyrannosaurus rex didn’t live during the Jurassic period. Although the tyrant lizard went down in history as a dominant dinosaur, it lived during the Cretaceous period, which came after the Jurassic.
