doushantuo Posted April 19, 2018 Share Posted April 19, 2018 That article tells you the why,how,and where of fossil distributions in the area. Which skeletal elements,how much of them,at what locations Orginal possible abundance,the influence of the environment,the stratigraphy,the taphonomy Might be helpful in developing your "search envelope" Plus,it's fairly recent Link to comment Share on other sites More sharing options...

This is a dromaeosaur hallux claw. Digit one. The grooves are asymmetrical the higher groove is on the lateral side the lower groove is on the mesial side. These are commonly misidentified as Troodontid sickle claws. But the head on view of the articulating end as well as the very convex medial side are telltale features of the hallux claws on dromaeosaurs. Troodontid sickle claws (Digit II claws) have a noticeably parallel lateral edges in the articulating end in head on view. Hallux claws show asymmetry and tend to be slightly wider dorsally than ventrally (but not always)in head on view of the articulating end as your claw shows. This is is a common and very understandable identification error. 1 Link to comment Share on other sites More sharing options...

Thanks for clarifying the difference between these claws and providing information on claw identification and the identification of my tyrannosaurid tooth as well. I'm very glad to know what these specimens are. Link to comment Share on other sites More sharing options...
MedicineHat Posted April 23, 2018 Author Share Posted April 23, 2018 This whole discussion has been fascinating and I am so thankful that you all took the time to express interest in my new finds! I can't wait to hit the field again and see what comes my way. I hope to photograph the next adventure to make it more interesting and informative.

Something I would want to hold. After more examination...I think modern claw. Not rock...organic I think. Oops! Link to comment Share on other sites More sharing options...

Basilemys is the genus in the latest Cretaceous Hell Creek and Lance Fm. Not sure what it would be called in the Belly River. Not common. This is what i thought too as i saw this material...
