Information report on Spinosaurus
Spinosaurus was the largest carnivorous dinosaur of all time. It had an enormous sail on its back growing to about 2 metres tall, a long neck, skull and tail. Spinosaurus grew to 15 to 18 metres and could weigh up to 11 tons. Its arms were as long as its legs for it was a quadruped and it wielded three claws. The claw on the first digit of the finger could grow up to nine inches perfect for pinning down huge fish like Onchopristis (on-ko-pris-tis). Spinosauruses snout was elongated and held 50 needle like teeth and were great at snapping up fish. It had a crest above its eyes and its nostrils were put high up on its snout so it wouldn’t drown when hunting. It was semi-aquatic which meant it lived on land and water. A Spinosauruses tail was very strong and helped the dinosaur swim. The reason they gave Spinosaurus this name was because the sail on its back was actually nine huge spines covered in flesh and skin rising from its back.
Spinosaurus lived in North Africa, mostly Egypt. In the time we live in right now north Africa is a barren desert wasteland, but around 120 million to 70 million years ago north Africa was a lush green paradise full of rivers, lakes and swamps. Since Spinosaurus was semi-aquatic, it lived very close to bodies of water and overall had a very wet life. The reason for its extinction was because of a huge meteorite. You may have already heard about the PE extinction event already but if you don’t know the PE extinction event is something caused by a huge meteorite that killed 95% of all living things on earth.
The Spinosaurus lived around 112 million years ago to 72.2 million years ago. This was in the cretaceous era, the time when the most well known dinosaurs like Tyrannosaurus Rex and Triceratops roamed the earth.
Spinosaurus had almost no dangers at all because it was the largest and most dangerous dinosaur where he lived. The only dangers Spinosaurus had were this other dinosaur named Carcharodontosaurus who was very close to the size of Spinosaurus and just as ferocious. We know this because we have evidence of fights between the two monsters. Another danger for Spinosaurus is drought. Since it was Africa, of course the sun was really strong so sometimes the rivers dried up destroying their food supply and dehydrating them to the point of killing the animal. Also giant meteor rights.
Spinosaurus didn't have a huge food variety. Like seriously it ate only fish. The kinds of fish it ate were Coelacanth and Onchopristis. Coelacanth was a large fish with seven fins and can grow to the size of a 7 year old boy, pretty much a piece of candy for Spinosaurus. It waited 52 kgs. Was black and had specks of white on its body. Onchrapristis was a huge Sawfish that grew to about 8 meters and weighed 700 KGS! There were also some dinosaurus spinosaurus ate like the duck billed Ouranosaurus which also had a sail like Spinosaurus.
Fun fact: Spinosaurus was the starring antagonist dinosaur in the movie Jurassic park ///, one of my favorite movies of all time. But a lot of people think otherwise.
