4 years, 8 months ago4 years, 8 months agoHi, @corinne-daycross, You can update your taxonomy to be Kingdom Animalia > Phylum Chordata > Class Chondrichthyes > Order Myliobatiformes. Maybe @fauve-wilson has suggestions on narrowing it in even further.
Here is the link to Macrostrat to help narrow in the geologic context:…[Read more]

4 years, 8 months ago4 years, 8 months agoHi, @hope-scheff – You can add in some of the higher order classification such as Kingdom Animalia > Phylum Chondrichthyes. I’m seeing some conflicting ordinal assignments Odontaspidida v. Lamniformes so I’ll let @fauve-wilson chime in on that.
You can use Macrostrat to figure out the geochronology:…[Read more]

4 years, 8 months ago4 years, 8 months agoHi, @grace-barnard – I think we can narrow your classification down some to Order Myliobatiformes and maybe? Family Myliobatidae, correct me if I am wrong, @fauve-wilson.
You can use Macrostrat to narrow in on your collecting locality:https://macrostrat.org/map/#/z=10.6/x=-82.3217/y=29.7107/bedrock/lines/ to get a better idea of geologic time but…[Read more]

4 years, 8 months ago4 years, 8 months agoHi, @lauren-norman – are you sure this species identification is correct? I’m not sure this species extends back into the Miocene. I’ll tag in @fauve-wilson to see what she says.
-
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.

4 years, 8 months ago4 years, 8 months agoHi, @savanna-zipperer – similarly with this specimen, being able to see the other side of the specimen is useful in identification. I’ll tag in our local shark expert – @fauve-wilson to take a look anyhow. Talk to you soon, Jen
-
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]

4 years, 8 months ago4 years, 8 months agoHi, @jacob-wall – Are you sure this isn’t a ray plate? It seems unlikely that it is a mammoth. @fauve-wilson and @vperez are local experts that can chime in on this. Talk to you soon, Jen

4 years, 8 months ago4 years, 8 months agoHi, @bianca-serrano – I think your identification is incorrect. You have listed out the common modern species of stingray. I’m not sure if it’s a ray plate – it looks strange to me. I’ll tag in some Gainesville experts for you – @vperez@fauve-wilson
Talk to you soon, Jen-
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.

4 years, 8 months ago4 years, 8 months agoHi, @justin-jones – are you sure this isn’t a ray plate? What makes you think it is a mammoth?
Let me tag in @fauve-wilson to take a look at this.-
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.

4 years, 8 months ago4 years, 8 months agoHi, @savanna-zipperer – Excellent specimen! The root is pretty fragmentary, which is key for identification. Let me tag in @fauve-wilson our local shark expert to see if she can confirm the ID. If you could add another photo of the other side of the specimen that would help too! Talk to you soon, Jen

4 years, 8 months ago4 years, 8 months agoHi, @cyrus-santiago – Maybe @fauve-wilson can chime in as an expert and local. Cyrus thinks this is either a lemon shark or possibly a dusky shark tooth – can you tell from the images they uploaded? Talk to y’all soon, Jen
-
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]

Unfortunately, a complete (or nearly complete) root is one of more important keys to identification. This helps determine if it an upper or lower tooth and even what Genus or species it is. In this case from what I am seeing, it could be a lower Carcharhinus (not positive) which with the exception of a few species are almost impossible to tell apart.
-
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.

4 years, 9 months ago4 years, 9 months agoHi, @alexander-levin – Could you include an image with a scale bar? Your dimensions are not correct or in different units.
Maybe @fauve-wilson or @vperez could weigh in on the taxonomy, geochron, or lithologic info?? -

4 years, 9 months ago4 years, 9 months agoHi, @bkent – Is the species unnamed or you are uncertain of the identification? I can chime in some of our sharky experts – @vperez@bill-heim@fauve-wilson to share their expertise with you.
I think you have a typo in Chesapeake, here is some information I found on the group: https://macrostrat.org/sift/#/strat_name_concept/1021
Talk to you soon,
Jen-
Dr. Bretton Kent is a fossil shark expert. He is a professor of paleobiology at the University of Maryland. There is nothing I could add to his information.

Everyone can improve upon their data entry, even experts. I wonder if this has since been published on, @bkent? Let us know and we can link in the publication.

-
huh, alas, I dont have any more information on this specimen. I think it may have been found on a FOSSIL trip to the Calvert Marine Museum a few years back. Since I did such a poor job with specimen information (sorry! : ( ) should I delete it?
-
No need to delete it! Let’s let our shark-y experts chime in. There is always room for outcast specimens on myFOSSIL! =]
-
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?
-
Agreed, nice job Fauve!!

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
