Myliobatis Latidens(?); Eagle Ray- tooth plate? **bonus points** anyone able to ID the rock/mineral as well??
DoubleD843 posted a topic in Fossil ID
Initial thoughts after doing quite a bit of research- Eagle Ray tooth plate. Not 100% sure on this. As far as the specific rock/mineral containing the fossil….perhaps rose quartz? Totally a shot in the dark here. Would appreciate any feedback! -

Psittacosaur9's Cabinet Renovation Fossil Identification - Mesozoic and Cenozoic Animals Thread
Psittacosaur9 posted a topic in Fossil ID
Hello everyone, and I hope you've all had a good day. I started to put my display cabinet together today, and after an exhausting day of work, I'm only half done and I haven't even started on the bookshelf! Yay! Sarcasm aside, I've got some more fossils I would like identified, as I am creating labels for my displays. Just as before, I would prefer the most specific identification possible - species would be preferable, but I would rather a genus or clade name over an invalid species name. Location would be helpful too. Again, if any of you want them, I can take more photos tomorrow. Specimen 1: Actinopterygii This specimen I purchased at a museum, which simply labelled it as 'fish fossil'. While I do not know the location, I suspected it was from the Green River Formation in Wyoming, as many commercially available Actinopterygii fossils come from that site. At first, I thought the specimen was Knightia, as that fish seems to be one of the more common from the Green River Formation, and the only common one of the same size and rough shape. However, after recently observing a slab of Knightia at a museum, I began to doubt my initial identification, as the Knightia in the museum looked more bloated than my specimen. Is it a Knightia, or something else? Specimen 2: Ammonite I apologise for the rather shoddy attempt at editing out the supplier's logo. As you can see, I purchased this ammonite in a small plastic case at a museum, and cannot take a photograph of it from all angles. However, the back of the box (or at least what survives of it) says that the ammonite is Jurassic of age and comes from Madagascar (thinking about it, the supplier probably had to stick the ammonite to the case in order to get it through customs). Therefore, after comparing it to other ammonites from the same location, I believe it is most likely a Phylloceras specimen, as those ammonites lived in the correct place at the correct time, and had the same shaped, relatively smooth shell. Do you all agree with this conclusion? Specimen 3: Gastropod Another specimen I purchased from a museum with no knowledge of its original location or age. Unfortunately, I know very little about Gastropods, so I do not know how to identify it. Do any of you recognise at least what group it came from, or even tell its species, time period or location? Specimen 4: Ray tooth I received this tooth as a gift in a set of various teeth from Chondrichthyes. The gift set identified the ray tooth as Jurassic in age, however gave no further information on the specimen. To add to the confusion, all of the fossil ray teeth I have found available to purchase online come from Myliobatis, a genus which only evolved in the Cenozoic. While I am pretty sure it is Myliobatis and the gift set's information was simply inaccurate, I would like confirmation that this conclusion is accurate. Also, I do know that there is only half of a tooth; it broke a while ago and I no longer have the second half. Thank you for all of your help! Next up will be a couple of Triassic plant fossils, and following that will be some fossils I am concerned are fake. Hope you all have a good night!- 21 replies

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.-

Hi guys. I have found a fossil for whom I presume is a myliobatis palate (medial). It was found in the eocene era site in Croatia, near city of Vrgorac. Thank you in advance.

1.5cm. long. Burdigalian, Miocene. Found at Billafingen in southwestern Germany. Eagle ray barb partial. Not absolutely sure about the id, but it certainly looks like the photos of that genus that I've seen.-

BusyEagle and I ventured out to the Potomac River Miocene/Eocene cliffs today to take advantage of the warm weather. Shortly after arriving the rains came down and drenched us. We toughed it out for a while, and just before turning back I spotted this in the cliff (sorry about the blurriness of this pic). Here is what it looks like after partial prep: Seven rows with two rows of side teeth, about 1.5 inches long. I will probably take it out of the matrix to expose the other side. This is my first ray plate from this bed in 25 years of collecting.

This is an eagle ray toothplate from the Suwannee River. Most often, these toothplates are disarticulated into single teeth. Note the wear on the occlusal surface, probably from crushing hard-shelled food items. Family MYLIOBATIDAE Subfamily MYLIOBATINAE Myliobatis sp. Late Oligocene Suwannee Limestone Suwannee County, Florida (This image is best viewed by clicking on the button on the upper right of this page => "other sizes" => "large".)© Harry Pristis 2015
