Toast123 Posted June 23, 2023 Share Posted June 23, 2023 This tooth is just shy of 4 inches, is this from an adult Spinosaurus? How big was it, based on the tooth size? I’m also curious if the bottom of this tooth is the root or worn enamel. Link to comment Share on other sites More sharing options...
Toast123 Posted June 23, 2023 Author Share Posted June 23, 2023 Is the bottom part peeled off enamel or the root Link to comment Share on other sites More sharing options...
Troodon Posted June 23, 2023 Share Posted June 23, 2023 Well first you cannot say it came from a Spinosaurus since there are multiple Spinosaurids in the Kem Kem and Spinosaurus may not be one, we just don't know. Isolated Teeth are never used to determine size of a theropod. The problem is that they are continually replaced so an adult theropod jaw can have all different size teeth. You can also be looking at an unerupted tooth. In addition the jaw of a Spinosaurid has many different size alveoli so position also plays a big factor. So the standard answer is at least a juvenile to an adult. The carina seems to end about the white line so that's most likely the crown. The rest with the smooth surface is the root.
