Dinosaurs


    Dinosaurs were amazing animals, they lived in the Cretaceous Period , which was the longest part of the Mesozoic Era. This article is going to be about five different types of dinosaurs: the Tyrannosaurus Rex, Pterodactyl, Apatosaurus, and the Triceratops.

Tyrannosaurus Rex


    The Tyrannosaurus Rex, or T-Rex for short, is a carnivore, meaning it only eats meat. T-Rexes had strong thighs and a powerful tail, which was counterbalanced by its huge head and allowed it to move quickly. A 2011 study, suggested that the giant could run 10 to 25 mph.
    Its two-fingered forearms were small (chicken leg small) making it unlikely that T-Rex could use them to kill or even be able to lift a meal to its mouth. However, it's possible that T-Rex had such tiny arms because it made up for that with its powerful bite (I would not want to on the end of that bite).
    The T-Rex would have had to have thick neck muscles to hold up its large skull and power its forceful bite. Neck and arm muscles compete for space in the shoulder, and it appears that the neck muscles edged out the arm muscles in the T-Rex's case. However, long arms can be broken, are vulnerable to disease, and take energy to maintain, so having short arms may have been beneficial to the king in the long run.

Triceratops 


    Triceratops were herbivores, meaning they only ate plants. They were around 30 feet long--the same as three cars--and weighed around 12 tons.
    It is believed that Triceratops mostly ate vegetation that was low to the ground such as ferns and shrubbery. Scientists believe that their large amount of teeth suggested that they ate large volumes of fibrous plant material each day and that these large batteries of teeth were needed to replace the ones that were damaged by wear and tear.
    Currently, there are two theories which suggest what the horns of the Triceratops were used for. One being that its horns were used to defend itself against other dinosaurs, mostly the T- Rex, which is known to have been its mortal enemy. The second theory suggests that its horns served very little purpose in combat and was instead used during mating rituals.

Apatosaurus


    The Apatosaurus (also known as the brontosaurus) was an incredibly large dinosaur alive during the Jurassic period. The Apatosaurus was a herbivore and was around 90 feet long from head to tail!

    The large dinosaur was believed to eat leaves off of trees and they had teeth that were chiseled so that the Apatosaurus could eat more foliage off the branches. An interesting part of their eating habits is that it is believed the dinosaurs would swallow stones that would help break down the leaves in their stomachs.

    Also, it was a theory tested by computer simulations that the Apatosaurus could use their tail to make a whip-like cracking sound. It wasn’t said what they would do with that technique, but it is a cool fact to know.

Velociraptor


    The velociraptor (meaning speedy/”swift thief”) was a pretty cool dinosaur living in the cretaceous. It was a carnivore and would eat lots of meat on a daily basis.
    The velociraptor was not a large dinosaur, but was very aggressive by nature. It was approximately 3-5 feet and could have been 30 pounds (less than a labrador retriever!) It was fast, and was very aggressive so it was a great scavenger. With its lightweight body, it was great for catching small reptiles and mammals, not large prey.
    An interesting fact that not many people know about the velociraptor is that it actually had feathers! While the velociraptor could not fly, it possibly could have used the feathers to help them run, or protect them from weather. Another fact is that the velociraptor is one of the dinosaurs that is closest to the bird species.

    Now that you have read our article I hope you learned something about dinosaurs you didn’t already know. They were truly amazing and fascinating creatures that other animals today continue to resemble.
