Identification of Claws/Unguals from the Hell Creek/Lance Formations
Troodon posted a topic in General Fossil Discussion
A member of the forum asked if I cam put a topic together to help identify claws from the Hell Creek/Lance formation. Its fraught with difficulty since so little has been published and described from these faunas but will attempt to put something together. All subject to discussion and mistakes. Although the focus there is with the dinosaurs of the Upper Maastrichtian its applicable to most of the other faunas of the Campanian and Lower Maastrichtian ages. Ceratopsian indet. This family of dinosaurs include Triceratops, Torosaurus and other large bodied Ceratopsaian yet to be described. Identifying unguals to a Genus/Species level is impossible and these are best identified as Ceratopsian indet. Ceratopsian unguals are best described as being rugose with many pits/holes on the front perimeter of the ungual. There is also a ledge (more pronounced on some than others) on the ventral side as shown by my red marks. I find it difficult to tell the difference between hand and foot unguals of the same size other than the wings are not has pronounced. The more symmetrical the wings are the closer the ungual is to the midline Digit III. Photos are the best way to show what they look like and here are some from my collection Dorsal view Ungual 1 Ventral View Ungual 1 Dorsal View Ungual 2 Ventral View Ungual 2 Dorsal View Ungual 3 Ventral View Ungual 3 An illustration of a Hand (Manus) A photo of a composite foot Leptoceratops indet. A small Ceratopsian in these faunas is a Leptoceratops. Teeth are the most common material found or sold but there are skeletal elements found. Here is an ungual I found in the Hell Creek. The dorsal view is like an isosceles triangle and very compressed. Dorsal View Ventral View Since these are extremely rare here is an additional photo of a associated set of unguals from the Two Medicine Formation An illustration of an campanian foot An illustration of a digit.- 29 replies

Finally finished up this pair of claws I believe belong to some species of Raninidae, though I'm far from certain. The concretion does contain at least some of the carapace, but it's in pretty bad shape. It seems to be badly crushed and poorly preserved. So I decided to leave that part alone for now and just prep out the claws, which were just starting to weather out of the front of the conc. Some day I hope to find a more complete specimen, but for now I'm pretty happy with this cool pair of claws.

I recently saw these British velociraptorine claws for sale. The smaller one is 3mm and the larger one is 5.5mm. Does anyone know what it could be and could it be nuthetes destructor (which would make it incredibly rare)?

This popped up online, some one in my local area is selling them, He's not sure what they are but says he believes them to be fossils. Look like claws to me but I've not familiar with this kind of thing. He has no info of where they are from but would like to know what they are.

From the album: Ursus spelaeus (Cave Bear) collection.
Ursus spelaeus finger bones and claws. I'm using my finger as scale so you can see how powerful these critters were! From the Dachstein Mountains in Steiermark, Austria. Pleistocene.- 1 comment
