Fossildude19 Posted January 3 Share Posted January 3 These are modern bones, correct? Moved to GENERAL DISCUSSION. Looks like a bird ulna (maybe??) on the left, and some sort of rib on the right. @Harry Pristis @Shellseeker @MarcoSr @Auspex Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

ClearLake Posted January 3 Share Posted January 3 The one on the left is a bird humerus and I assume also that it is recent. You can tell its a humerus by the subdued S shape to it, the larger femoral head, and the round knobs on the smaller end. Based on the figures (and size) in Gilbert, et al's Avian Osteology, it seems to fit best with something like a cormorant (Phalacrocorax). I have a Turkey Vulture and Loon to compare to and it is not either of those. I'm estimating the length based on what we were told for the bigger bone. A more precise length and some better pictures of both ends might help to confirm an ID. Rib is as detailed as I can get on the larger one as well. 1 1 Link to comment Share on other sites More sharing options...

I agree... bird humerus, but just to keep folks honest... a femoral head is found on a femur. The humerus has... a humeral head. : ) I'm sure that was an oversight, but just so others learn the correct terms. Link to comment Share on other sites More sharing options...

I will check a bit later and see with the new pictures and info if I can improve an ID on the humerus. 1 Link to comment Share on other sites More sharing options...
