Medium sized Rancholabrean mammal radius?

Recommended Posts

Before anything, Hi everybody Im new here.

 

Well, I just found this "radius" like fossil in a load of pumice sand for construction. I dont know exactly from where it comes, but all around here is Rancholabrean pumice. 

 

At first sight it looked like a rib, but now I think is a radius (or maybe an ulna). Unfortunately both tips are missing. I know have the complete bone is necesary for a more specific determination, but I wonder if Order or Family level determination is possible.

 

I had compared with some pictures and the closer things I have now are some medium size feline, a "gracil" artiodactyl or even a human?!

 

Can somebody help me with this please?

For those who do not know, the Rancholabrean is a North American land mammal age roughly contemporaneous with the mid-late Pleistocene. This does not look human to me, I’d say a cursorial animal, gut says herbivore for some reason. I knew my logic isn’t that scientific, but maybe someone else has a definitive answer, how about @Harry Pristis?

Can't help with the ID, but wanted to say a very warm welcome to the Forum from Morocco! :)

Welcome to TFF!

Without the ends of the bone there is little chance for a definitive ID. There are no diagnostic features.

Thanks everybody.

 

With out the tips I had turned my attention to the form and proportions of the bone´s shaft.

For now the closer things I have are some carnivore like Lynx or Canis, an artiodactyl like Odocoileus (I cant find good pics to compare with Antilocapra) and the much more improbable Homo.

 

I could be very happy if we can achieve at least Order level.
