FF7_Yuffie Posted May 23, 2021 Share Posted May 23, 2021 (edited) Hello, This fossil caught my eye as one to buy. It is described as a radius--23 inches long. Seller doesn't know the species, but speculates it could be theropod. Am I right in thinking it is actually Edmontosaurus? It is from Hell Creek, Montana -- near the town of Jordan. I did a bit of looking, and 23 inches seems far too big for any of the Hell Creek theropods. Edmontosaurus radius bones look around the same length--a google search shows some previously sold which were around 20 inches plus. The weight is just under 6lbs. So, am I correct with it being Edmonotosaurus, or is there another species it could be that I've overlooked? Also, I am curious about the white patch. Is that a sign of restoration, or just some type of weird weathering? Thanks Edited May 23, 2021 by FF7_Yuffie Link to comment Share on other sites More sharing options...
Troodon Posted May 23, 2021 Share Posted May 23, 2021 Yep good call. Looks like an ulna from an Edmontosaurus. The white or cream colored patches are where it was exposed to the sun. It . Might have some fill/resto in the proximal end pic 5 and 7. Partial surface find and proximal end a bit weathered 1 Link to comment Share on other sites More sharing options...
