Hi!. I found this item on the internet. The seller claims that it is an original and natural pterosaur hand claw. I've never seen pterosaur bones so I can't understand. Can someone try to explain to me if it is true or false? Here some data: Location: Erfoud in southeastern Morocco Species: Pterosaur Family: Anhanguera Period: Upper Cretaceous There aren't info about dimensions. Regards.

I just want to let everyone know that there appears to have been a theft of a big and beautiful Spinosaurus Hand Claw at the Tucson Show. Would like everyone to be on the alert if they see one offered for sale. Thanks Contact: Kendal at geosourcellc.az@gmail.com

Hi, I have been offered a Kem Kem claw which I think is a theropod hand claw, but when it comes to claws from the Kem Kem, I have little idea on how to spot composites or claws made out of carved bone (or at least, I worry too much about Kem Kem claws no matter how good they seem). Wanted to ask if someone can help me determine if this claw is real, and if so, are there any repairs done on it. Thank you!

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.
