Edmontosaurus Astragalus from Hell Creek, South Dakota

[TeethCollector]

I want to share a nice Astragalus of an Edmontosaurus, from Tooth Draw Quarry, Hell Creek Formation, South Dakota.

According to the shape of the fossil, I guess this is from left leg of the Edmontosaurus.

And, this is a neural arch of an Ornithischian dinosaur, from Tooth Draw Quarry, Hell Creek, South Dakota.

A lot of restoration work done at the articular process of the neural arch.

 

Since most of the identification parts are missing, I have no idea what genera it is. Seller mentioned that this is most likely Triceratops or Edmontosaurus...
