I agree with Victor on the family. It looks like it belongs to the genus Aetobatus

Hi, @lauren-norman. I don’t think that Rhinoptera bonasus is correct here. If you can provide an image that has a scale bar and possibly a different view, it may be able to be identified. Currently I think it’s safer to identify under just the family of Myliobatidae.

Hi @jacob-wall, I don’t agree that it’s Rhinoptera bonasus. The orientation of the teeth on the dental plate lead me to think that it’s part of the Aetobatus genus. Any idea what species it may be? A photograph of the other side of the plate may be helpful here. -Fauve

Hi @savanna-zipperer, it is in the carcharhinus genus due to the serrations on the shoulders, and it’s a lower tooth, but I don’t believe that it is a Dusky. If you can provide a labial picture as well, that may help, but the specimen may just have to stay at Carcharhinus sp.. When it comes to requiem sharks, there are a lot so, without a clear…[Read more]

Hi, @cyrus-santiago, because of the sediment still attached to the tooth, it is hard to pin point even with a scale bar (thank you for adding the scale bar by the way). If you think that you can wash away some of the sediment, we may be able to get it down to specific epithet, but for now I would put it under the genus Carcharhinus. Lemon sharks…[Read more]

Hi, @bianca-serrano, would you be able to take a picture of the other side of the specimen? The picture posted already does look strange even to myself, Dasyatis teeth are very small and are normally not shaped like this structure, so another view may help with a more firm identification.

Hi, @justin-jones, I would agree with @jbauer that it is a ray dental plate. The coloration seems a bit off for this area, but judging by the wear (which happens a lot in the family Myliobatidae) and due to the size I think Myliobatidae is the correct call.

Hi Daniel! Thank you for adding a quality photo with a scale bar in your pictures, it really helps curate the specimen. Your information here looks correct, but I am pressed to agree that it is the rarer Carcharoides totuserratus since the root is so worn and pocketed unfortunately. If you still have the specimen, would you have a different genus…[Read more]

Hi Mike! Do you happen to have any clearer photos of this specimen? Then we might be able to at least report a genus for classification

I do agree with Bill here. Without scale and with some of the root missing it is hard to give an exact ID. If you have the specimen still, a clear photo may help narrow it down further.

Possibly a ray barb? If you still have the specimen, a picture with a scale bar would make it easier to ID.

Hi Mike, I agree with your information again. Was this tooth donated to a museum?

Hi Edesse, could you provide more information about the geochronology and lithostratigraphy for this tooth if possible? This type of tooth is not usually found in Gainesville, especially in this great of condition.

No worries! Its a great tooth so thank you for the upload!

Hi Lisa! Sorry for the late “shark-y” chime in 🙂 Its hard to bring it down to species because the specimen is missing the root and from the picture quality here, but it looks to be the lingual view of the genus Galeocerdo (Tiger Sharks). Do you happen to still have this fossil?
