Spinosaurus is estimated to have been 49 feet long. The weight estimates are far more sketchy, though, as we don't even know Spinosaurus from any complete skeletons. They range from 4.4 to 10 or even 18 tons.
a spinosaurus teeth was the same as crocodiles teeth today
Spinosaurus teeth were the size of well i'm not really sure but my guess is a tv remote or as big as a saltwarter crocidile.
BIG
Based on the shape of its teeth and claws, scientists believe that spinosaurus primarily fed on fish.
The type species of Spinosaurus is Spinosaurus aegypticus, and it is known from fossils found in Egypt. The other possible species is Spinosaurus maroccanus, and it is known from teeth found in Morocco.
I'm afraid I don't have the answer to the precise study that proves it, but there are many images available of dissected or otherwise broken Spinosaurus teeth that reveal that they were hollow. fossil jaw fragments with broken teeth reveal that they were hollow. But the precise study, I'm searching for that myself.
mapusarus would win in a fight because spinosaurus only ate fish so its teeth were small and brittle plus it was only 18 to 20 feet tall so spinosaurus would not win under any cercomstanses
No, because fossils are pretty rare including teeth. But if you live in a place where there was a lot of dinosaurs then it is very possible for you to find types of fossils.
It is small if you want proof go on google images
The spino had a crocodilian head. It was filled with inward-pointing canine teeth. The inward design was meant for keeping the prey from escaping its mouth.
Because Spinosaurus was 49 feet long and weighed at least 4.4 to 10 tons, the size of an adult was its first line of defense. As for young Spinosaurus, their best defense probably would have been to flee. If an adult were attacked, it would have used its teeth and jaws and possibly its arms to fight back.
Big.. Personally, i like big teeth better than small. Not HUGE teeth, but having big teeth makes u have a better smile:)
Spinosaurus was a fish eater, or piscivore, and adaptations for fishing include its long, narrow jaws and non-serrated, interlocking teeth. Spinosaurus may have even had pressure sensors in their jaws for detecting fish in the water even if they couldn't see the fish. The enormous size of Spinosaurus, at 49 feet in length, would have made them intimidating to other dinosaurs. Of course the spectacular sail of Spinosaurus was an adaptation. It may have been used to either cool or heat the Spinosaurus, to attract mates, or to intimidate rivals.
