Hell Creek Fm Alvarezsauridae Described

[Troodon 19,363]

Every few years we get rewarded with a new dinosaur described from the Lance/Hell Creek Formations.  In this crazy year we finally have one.  Finally an Alvarezsauridae has been described from the Hell Creek Formation: Trierarchuncus prairiensis.

Here is some info on this very different dinosaur, one of my favorites, including some of my material so you can see what the paper is describing.   Far better than what you see in the paper

I had no luck finding anything other than a very overpriced claw from the HC Alvarezsauridae when I was searching but it’s cool to have it described. 

 

Thanks for posting this Frank
