Deinocheirusmaster! Posted August 1, 2018 Share Posted August 1, 2018 I recently bought a Spinosaurus tooth from a fossil shop on the Rocky Moutains. I noticed this little ridge on both sides of the tooth. I looked at some pictures on the internet and im inclined to beileve that its from the premaxilla. Supposedly the teeth from the premaxilla are pointed with sharp edges on both sides. Could this tooth be one of those? Note that there is feeding wear on the tooth.

Troodon Posted August 1, 2018 Share Posted August 1, 2018 I dont believe we can distinguish between the different tooth positions in Spinosaurids. Not sure if a Premax has ever been found with a full set of complete teeth in it to make that call. So we know very little. Your tooth is pointed because of the wear facet on the side which occurs by contacting the opposing tooth in the jaw. This is how a Premax and Premaxillary jaw typically look like when found. 5 Link to comment Share on other sites More sharing options...
LordTrilobite Posted August 1, 2018 Share Posted August 1, 2018 Yup, no way to know. But the wear facet is pretty cool. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
