Allosaurus Posted June 10, 2019 Share Posted June 10, 2019 I have a couple other teeth in question. Any help is appreciated. Is this one a tiger shark? There are serrations. Link to comment Share on other sites More sharing options...
Allosaurus Posted June 10, 2019 Author Share Posted June 10, 2019 I have quite a few of these little curved teeth, some with roots and some not. The teeth are hooked/curved pretty significantly. Link to comment Share on other sites More sharing options...
Allosaurus Posted June 10, 2019 Author Share Posted June 10, 2019 Last one for now. I know this is just a partial, but it's bugging me on what it could be. I see no evidence of serrations with my hand lens. Link to comment Share on other sites More sharing options...
caldigger Posted June 10, 2019 Share Posted June 10, 2019 * The first looks to be Galeocerdo aduncus ( Tiger ). * Second container has several different teeth in it. From what I can see, you have some Dasyatis ( ray teeth ), Squatina ( Angel Shark), Cetorhinus ( Basking Shark) and perhaps a couple other smaller teeth with broken off roots. * Third single tooth in hand is the Squatina ( Angel Shark) or as I like to call them...thumb tacks. * Fourth item in the container is partial piece of Hexanchus andersoni ( Sevengill Cow Shark) lower tooth. 5 Link to comment Share on other sites More sharing options...

Allosaurus Posted June 10, 2019 Author Share Posted June 10, 2019 Thank you so much for all the help! I've separated some of the teeth out of the container in the 2nd pic to confirm a couple other things as I've been looking more closely. 1st pic. Are these the angel shark teeth (I've poked myself a few too many times handling them haha). 2nd pic. Cetorrhinus? 3rd pic. I think I see 2 angle shark teeth, and are the two uppermost ones also cetorhinus? Not sure about the 2nd one from the left. 4th pic. Is the dasyatis the bottom one?
