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.

Megalodon

 { I just want to point out straight away that Megalodon did not live at the time of dinosaurs, but I did it anyway cause I treat it like it did } The Megalodon is the biggest shark to ever live! Apparently, it could reach 69 feet long!, snout to tail tip! Megalodon means "Big Tooth". Did you know, that once, a kid was digging on a beach under rocks, and found a Megalodon Tooth! If the Megalodon were still alive today, Humanity would be extinct! Megalodon went extinct 1 million years before humans, 2.6 million years ago. Their have been many "claimed" Megalodon sightings.

Ceratosaurus

 The Ceratosaurus was discovered 1884 by Othneil Charles Marsh. in Colorado. It lived 156 million years ago in the Jurassic Period. It was a carnivorous Theropod. It's biggest rival is Allosaurus."Nah! This is my territory!" they roared at each other for a couple million years I guess. Fun Fact, when Marsh found the skeleton, he thought that the dinosaur was gonna be an excellent swimmer. But it doesn't have a long snout to go fishing Brainypants!

Archaeopteryx

 The Archaeopteryx was discovered 1980 in Germany. Now, the Archaeopteryx could not fly, but glided from tree to tree, snatching insects as it did so. The name Archaeopteryx means "Old Wing". It has been referred to as the oldest known bird. But it's actually not. Yes, I'm sure I mentioned this before, but, birds are dinosaurs! Okay!? The first skeleton of Archaeopteryx was a headless bird!
