Some dinosaurs were really big and bloodthirsty fellows. Acrocanthosaurus was one such heavy-weight candidate. Enormously large, this big predator will at first glance look like a T-Rex but it is not. There are many significant differences. So let us today learn 15 interesting Acrocanthosaurus facts and find out a little about their lifestyle and generation.

At a glance: Lived: 125 million years ago. Food: Meat. Species: A. atokensis.
Acrocanthosaurus Facts 1-5
1. Acrocanthosaurus was a large, in fact a massive, theropod dinosaur that lived in the Early Cretaceous period, i.e. some 125 million years ago.
2. Acrocanthosaurus is pronounced as ACK-roe-CANTH-oh-SORE-us. The name is actually a Greek word which means ‘high-spined-lizard’.
3. The dinosaur derived its name from its unique physical appearance. It had a ridge running along its back.
4. Scientists believe that the spine or the ridge was responsible for supporting a muscle ridge over the neck, back and hips of the animal.
5. Acrocanthosaurus used to live in today’s North America during Aptian and Albian stages of the Early Cretaceous era.
Acrocanthosaurus Facts 6-10
6. Acrocanthosaurus was the largest theropod in the ecosystem it lived in and was probably an apex predator.
7. Its diet consisted of meat and most probably hunted ornithopods and sauropods.
8. Acrocanthosaurus was about 40 feet long and weighed around 6.2 tons.
9. This dinosaur was a bipedal animal.
10. Acrocanthosaurus had very powerful jaws and legs.

11. The arms of the animal were stunned. These arms or forelimbs never made contact with ground and never aided in locomotion.
12. Scientists believe that the forelimbs or the arms were primarily for predatory functions.
13. The olfactory bulbs of the Acrocanthosaurus were large. This indicated that the dinosaur had very well-developed sense of smell.
14. Getting back to the neural spines, scientists believe that the ridge may have served the purpose of fat storage or body temperature control.
15. Scientists also believe that those neural spines may also have served as sexual display. Scientists believe the males with bigger and prominent spines had the opportunity of mating with more females than males with smaller spines.
