Micro tooth Id

[Grimlock]

Hi everyone. I was searching through some micro-matrix from the Peace river the other day and found this little tooth. It is about 5mm long. I am pretty new to looking at these kinds of fossils, so any help on the Id would be appreciated. I know the picture isn't great, but its the best I can do right now.

That is a nice tooth! can You get some pictures from different angles?

I lightened your photo a bit. Hope you don't mind. That sure reminds me of whaleshark tooth. I've not ever found one of those in The Peace matrix... there are a lot of worn symphyseals that can look like that as well.

Whale shark is where my mind went as well but I'd have to go find some comparison images online. I agree that it could also be a worn symphyseal. So basically I'm really just parroting Julianna's comments above but adding my support to her thoughts in doing so. A few more angles might be nice as well as a bit more detail (difficult without a digital microscope).

Cool tooth--I'd enjoy seeing that pop-up while sorting through micro-matrix.

Cheers.

I agree with whale shark tooth.

I think we have a consensus forming for Rhincodon typus, the Whale Shark. Funny how a shark the size of a Megalodon can leave behind teeth you'll only find by picking through micro-matrix. I've now started to find some teeth of the (surprisingly) related Nurse Shark, Ginglymostoma cirratum, in my micro-matrix. Both species are currently classified in the order Orectolobiformes or Carpet sharks. I found another worn Nurse Shark tooth recently but have yet to score a really nice quality specimen. I think I'm going to have to go collect some micro-matrix in Gainesville (Rattlesnake Creek) where I've seen some gorgeous specimens that were found there. Nurse Sharks are quite common today (maybe only relatively so due to the severe depletion of all other species of sharks) but their teeth are not very common in any of the micro-matrix collections I've made (so far). Whale Sharks are (at least at the present) rare enough to make the news in Florida when one is spotted by divers or boaters. I can't imagine how ridiculously rare these teeth have to be in the micro-matrix fossil record. Because of this, this species tops my wish list while sorting through micro matrix.

Great find. I'd set that tooth off and display it alongside a nice big meg tooth because it would invite questions form anyone who sees it (and because I have a warped sense of humor).

Cheers.

The crown seems rather small relative to the root, though overall it is about the size of a whale shark tooth. The specimens I've seen bear a more angled or upright crown relative to the root. Does the root end branch off into lobes? If not, it isn't a whale shark tooth.

If you show a photo of the opposite side, that might help.

I agree with Jess. The root seems too high in relation to the crown. I'm not convinced it is a whale shark tooth either. Below are two pictures of whale shark teeth where you can see the root lobes that Jess is describing.

This tooth is eerily similar to a Basking Shark (Cetorhinus maximus) that I have from Lee Creek. Just a thought.

for comparison .....

Most likely you have found a Notorynchus sp. upper anterior tooth (sevengill). I too have mistaken a few very similar specimens for whale shark teeth in my less experienced days, but there are small discrepancies in the root angle and shape, as well as the nutrient groove that is present on most Anterior Notorynchus teeth. Look up pics online and you will see the similarities between your tooth Nd Notorynchus.

Getting back to this...I think we could use a view of the opposite side. Also, is the crown like a cone or does it have a somewhat flattened surface from another viewing angle?. I think we need to eliminate the option that it could be a broken-off lateral cusplet of a large sand tiger. I also thought about it being a dolphin tooth. I don't see it as a basking shark tooth because the crown should be at a sharper angle from the root and the root tapers too much.

I'm with Sixgill Pete on this one, based on the photos. Better photos may make me change my mind, but right now it just doesn't look enough like anything else in the provided photos.
