Megalosaurus

 Megalosaurus was the first dinosaur EVER DISCOVERED! In 1676! Back at that time {320 years ago} People thought the skelotons of this amazing dinosaur were the skelotons of some, prehistoric giant human being! Crazy right? People from China {no offense if your Chinese} thought they were dragon skelotons it wasn't till over 100 years later people found out that this was no giant human being, so they called it, Megalosaurus, and pt in the family Dinosauria! It lived 181 million to 169 million years ago, in the Jurassic Period. It was a carnivorous dinosaur, mainly hunting on dinosaurs like Stegosaurus, or stegosaurs. It was discovered in southern England. {By the way, Chinese people found these skelotons when they traveled to England}.

Tarbosaurus

 The Tarbosaurus was discovered 1946, in the Gobi  Desert. Tarbosaurus was originally thought to be a Tyrannosaurus Rex, so they called it, Tyrannosaurus Bataar in 1955. But soon they realized it was a new dinosaur, and corrected it to Tarbosaurus Bataar.

Comsognathus

 The Comsognathus has only two specimens found! One from France, and one from Germany. It is thought to be the smallest dinosaur ever, but give that a big fat X because Comsognathus was about the size of a chicken, while Lagosuchus was the size of your HAND! That's right, hand! Comsognathus mostly feasted on insects and small lizards, smaller than Comsognathus, of course. It's teeth were the size of your fingernail.

Troodon

 The Troodon was discovered October 1855 by Ferdinand V. Hayden. Troodon is one of, and possibly THE smartest dinosaur of all time. But it's body was very small. But that doesn't change how amazing this dinosaur is. It lived about 76 million years ago, in the Cretaaceous Period. It was actually thought to be a fossilized lizard until 1877 { you will see 1877 a lot because that was when two paleontologists challenged to see who could name more dinosaurs, I call it, Dino Year }. Troodon { like almost every other Dromeosaur on the planet! } probably had feathers on it's body.

Pachyrhinosaurus

 Okay, if you want to know everything you need to know about this dinosaur, just get the movie, Walking With Dinosaurs. I'm kidding please don't! Have you stopped? Okay.

Spinosaurus

 The Spinosaurus was discovered in Egypt in the year of 1912, and was described by a German Paleontologist in 1915. The Spinosaurus { like the Suchomimus } could go fishing with it's long snout. It is thought that it would have been one f the greatest rivals of Tyrannosaurus Rex. It actually lived before the Tyrannosaurus Rex about 112 million to 93.5 million years ago. It's diet mainly remained on fish and pork, I mean small reptiles. Spinosaurus means "Spine Lizard" because of the large sail on it's back.
