Zenmaster6 Posted April 25, 2019 Share Posted April 25, 2019 I found this bone in a ditch with no teeth marks or chewing on it. Obviously I believe this is modern as it still smelled of death and decay (I ran it under soap and boiling water and then rubbed it with sanitizer. and even then I don't touch it without a napkin) I was curious if my hypothesis was correct about this being a deer femur bone? I wasn't sure because I'm no bone expert but maybe someone here knows, all I know is we have deer, bears, cougars and possibly elk or moose but that would be rare. This was found in a creek by Murdock beach Washington State on the Olympic Peninsula (temperate rain forest conditions near large ocean.) Link to comment Share on other sites More sharing options...
Osteobyte Posted May 1, 2019 Share Posted May 1, 2019 This looks good for deer. It is a humerus, missing the unfused proximal humeral head. 1 Link to comment Share on other sites More sharing options...

Thank you for your knowledge. What a let down. I was told by someone it was a cougar humerus. Link to comment Share on other sites More sharing options...
fossilus Posted May 3, 2019 Share Posted May 3, 2019 A cougar numerous has an epicondicular foramen, a hole that would be near the right end of all your photos. 3 Link to comment Share on other sites More sharing options...

Right you are! A close-up of the entepicondylar foramen of a small, Early Miocene mustelid. This canal occurs near the distal end of the humeri of many taxa. This is the canal traversed by the median nerve and the brachial artery which is called the entepicondylar foramen (EECF). An EECF is found neither on the humeri of perissodactyls (horses, tapirs, et al.) nor on the humeri of artiodactyls (antelopes, camels, et al.), nor is it found in lagomorphs (rabbits and such). The EECF is absent in hyaenids, bears, and canids (including foxes and chihuahuas). The EECF is present in didelphids (opossums) and in shrews and moles! (Micro-fossil collectors take note.) The EECF is present in felids, in viverrids (all Old World), in amphicyonids (bear-dogs), and in mustelids (weasels and skunks) and procyonids (raccoons). 4 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
fossilus Posted May 3, 2019 Share Posted May 3, 2019 Thanks Harry! This is a photo of a cougar humerus showing the EECF, just like Harry's mustelid humerus. The 7-10 scale is in inches, the total length of the humerus is right at 9 inches. Link to comment Share on other sites More sharing options...
Zenmaster6 Posted May 3, 2019 Author Share Posted May 3, 2019 Thanks everyone. I'll probably ditch this if its a deer bone. Its smells rank anyways Link to comment Share on other sites More sharing options...
