Hello! Help please to identify a genus. I didnt found before such teeth... I saw some teeth on the ealsmo.com with some similarity (planktivorous rays) but they have others crown... Length: 5 mm. Age: Middle Miocene. Western Ukraine. Thanks in advance!

The top two are ray dermal scutes, they are like scales embedded in the skin of the ray. Ignore the bottom two.-

These ray teeth are often assigned to the genus Myliobatis but other authors dispute this designation. They are certainly some ember of the family Myliobatidae.-

These ray teeth fit together to form a broad, flat crushing dental plate. The lowers have a distinctive V shape and the uppers have rounded, slightly swept back ends.-

Well, I know I said my last post on these tiny fossils would be my last, but I was wrong. Everyone was very helpful with the previous questions (as usual) so I'm back with a couple more tiny teeth out of the Gainesville Creek matrix that is generally Miocene aged Hawthorn Fm. All of these are pretty small, most just a few mm's across. You can see previous posts here for other info or ID's: http://www.thefossilforum.com/index.php?/topic/119097-gainesville-shark-teeth-question/&tab=comments#comment-1305867 http://www.thefossilforum.com/index.php?/topic/114209-north-florida-fun/&tab=comments#comment-1264293 http://www.thefossilforum.com/index.php?/topic/119245-florida-mysteries/&tab=comments#comment-1309402 The first one is what I have tentatively called a Raja type tooth. But I know these are rare out of this material and it looks a bit different than other teeth labelled as this, so I am uncertain. Sorry for the big globs of sticky stuff in two of the pictures, I still have not mastered some of the fine points of pulling individual features out of pictures to clean them up - a work in progress. The next one are some ray dermal scutes. OK, I feel pretty good about the top two, but not the bottom two. In fact the lower right is almost certainly something else, I just don't know what. Any thoughts? Next up are some drum fish type teeth. I have separated what I picked from the matrix into three general types, two of which I feel good about the ID's. The first are what are generally called Pogonias, a genus of Drum fish. In this matrix, they are generally small, black in color, variably shaped and with a root that is rather plain (two on right side of picture). They are set as one layer of teeth in a bony plate. The second group of teeth are often blue in color, tend to be oblong, often have a figure-8 shape to the root and I found numerous multi-tooth associations where there are many teeth stacked on top of each other. I found several posts on the the forum and on the web that identified these as wrasse teeth, probably of the genus Labrodon. It is the third set of teeth that I am unsure of, they look similar to Pogonias, but generally are not as black and smooth and have a different root. it is a bit tapered and is striated. Any idea on what these are from? Lastly are several types of what I have thrown into my "unknown fish teeth" bucket. Maybe that is how they will remain and that is fine, maybe some are not even fish teeth. If anyone recognizes any of them, that would be great! The first two look similar to barracuda teeth, of which I found many, but differ in shape a bit. The first ones are thicker and not as symmetrical as my barracuda teeth and the second ones have a distinctive "S"-shape to them. The next ones: I just don't know. Ok, that's all for now. Thanks for any help you can offer. Mike

Took the relatively short trip down to Purse State Park last weekend and had quite a bit of success! Best find was certainly a fairly large chuck of what I think is turtle shell, along with a very much alive turtle that rested with us for our lunch before returning to the water. The dream of finding anything marine mammal or a somewhat complete ray plate remains for next time!

Here is another Cabezon taxa that I am having a hard time identifying. Is it Pseudohypolophus? Rhombodus? Myladephus? Something else? Any help will be greatly appreciated! Randy

Hello, below are photos of some verts I found at Big Brook Park in Marlboro NJ. (Late cretaceous, Mount Laurel formation). I thought they were both ray verts, upon taking another look however I noticed there are some slight differences in their build. I wanted to see if anyone had any clarification for me. I've checked the usual sites, njfossils.net and njfossils.com, but I think I don't know how to interpret different features. I took photos of each face (anterior, posterior),and tops and bottoms (dorsal/ventral sides). Both were found, to my knowledge, in the Mount Laurel formation at Big Brook. I also tried to take a close up of what appeared to be spinal process attachment points on the smaller vert. Aside from one vert being more oval than the other, the larger seems to decrease in surface area/diameter from anterior to posterior, while the smaller seems to form a wedge or "v" shape along the dorsal-ventral axis. I tried to capture this in the photos but I'm limited by my equipment. Ultimately, I'd like to confirm if these are both ray verts, or if either come from anything else. Thank you, Pic A (possible process attachment points on small vert): Pic. B Pic. C Pic. D: Pic E

I have two unknown fossils one being a tooth and the other I believe is a ray mouthplate/jaw bone. Sorry about the photo quality on the mouth plate it had a strange shape. Thanks

I found this yesterday on a fla beach. Appears to be fossilized dental plate from a ray. Can anyone help me verify the ID and estimate the age. Im guessing based on internet photos.

Hello! Help please to identify this fossil. I think that it is tooth of some Ray. May be, Torpedo..? On a second photo - together with a male Dasyatis. Max. radius - 1,5 mm. Middle Miocene. Western Ukraine. Thanks in advance!

Recovered the below bone from the Peace River a few weeks ago and put it aside thinking it was a partial bird bone or small reptile. On closer examination I can see serrations running along the length of the two sides. This now has me thinking Ray barb. The specimen is 26mm long by 10mm at the wide joint end. Any input would be appreciated. Thanks.

In February, I sifted at the shoreline on Caspersen Beach and Venice Beach, Florida. Finds include: (left) a crab claw & 2 ray tail barbs..... plus a variety of small shark teeth and ray mouth plates.

My question is exactly in the title, Can you identify ray teeth without locality info? I got some as a gift a long time ago and have no information on location and age and was wondering if its possible to identify to genus or even family

Howdy! How do you tell a Shark Vertebra from a Ray Vertebra? I can't seem to find much info online about Ray Verts. I came across (and vaguely remembered reading on a post) that ray vertebrae are more rectangular....is that true? Here are a few vertebrae that I think might be ray and if I could get a positive yay or nay on that.....I'd be very grateful! These are from Post Oak Creek in Texas - Cretaceous Era Size 4mm Size 3 mm
