Hello dear forum members, Here I have a damaged sloth ungual supposedly from Paramylodon (see description in the last pic) Is it possible (for some of you) to determine which finger or toe it belonged to? That would be great. Thanks J

Hello, a set of Thescelosaur bones --radius and phalanges and ungual that I am interested in. From Montana USA. Not all from same specimen (except the phalanges). Anyone think it all looks ok, or see any red flags?

Hi again TFF! I pulled this little guy out of some Aguja Fm matrix and my first thought was possible theropod ungual. It is a massive 4mm in length. Thoughts?

Spending some time in the house picking through some micro-matrix I collected last time I was out on the Peace River. The fine gravel is more worn and polished than from other sites (like Cookiecutter Creek) but that is to be expected since the Peace is a much larger waterway with a greater flow (especially in the summer when the gravel is being deposited). Most of the small shark teeth tend to be worn as well but not as much as you'd find from specimens picked up from the surf zone of places like Caspersen Beach in Venice, FL which produce a lot of teeth that look like they've been through a rock tumbler. Few novelties seem to come from the Peace River micro-matrix (compared to other micro-matrix sites in Florida) but an interesting little ungual turned up yesterday. My suspicion is that this is likely a turtle claw core but I see so few of these that I can't distinguish avian from terrapin. Anybody have a thought on this little find? It measures 7.5 mm from end to end. Cheers. -Ken

Curious if anyone actually knows the difference between croc or turtle/tortoise unguals? Are there any diagnostic features? Have this ungual that we've always been in-between as to what it is:

Who thinks this Wealden claw (my fossil) is Oviraptorid? What are the diagnostic features, anyone know....Henry?? Looks like it could be either to me - Dromaeosaurid/Oviraptorid. It is interesting that we also have maniraptoran confirmed at this locality, so this is another one to consider when identifying small elements like this. I am finding very small theropod dinosaur bones and claws that could belong to these animals. Currently Oviraptorids are only known from the late Cretaceous! And only in Asia. Yet some forum members have identified this as Oviraptorid...a big deal if they are correct....but are they?! The Wealden claw Dromaeosaurid claw Oviraptorid claw

The smallest biggest theropod dinosaur: a tiny pedal ungual of a juvenile Spinosaurus from the Cretaceous of Morocco https://peerj.com/articles/4785/ Abstract We describe a nearly complete pedal ungual phalanx, discovered in the Kem Kem Beds (Cenomanian) of Tafilalt region, south-eastern Morocco. The bone is symmetric, pointed, low, elongate, and almost flat ventrally in lateral aspect. This peculiar morphology allows to refer the specimen to the smallest known individual of the genus Spinosaurus. The bone belongs to an early juvenile individual and it is proportionally identical to the ungual of the third digit of a large partial skeleton recently found, suggesting an isometric growth for this part of the pes and the retention of peculiar locomotor adaptations—such as traversing soft substrates or paddling—during the entire lifespan.

Collected recently from Bouldnor on the Isle of Wight. It is about 33 million years old (earliest Oligocene). Fossils of turtles, a small alligatorid (Diplocynodon) and land mammals (most commonly anthracotheres) are the usual finds. This is the first ungual i have ever found from this location, and i am having trouble finding images of other examples to compare with. It measures 18mm long. I first thought crocodile when i collected it, but i would like other opinions. I'm now tossing up between mammalian and crocodilian. I understand going further than that will probably not be possible. Cheers!
