Hey everybody I've been deep diving into this forum for the past couple weeks while restoring this fossil. I found it in the Hell Creek Formation by the Powder River in Montana, on my brother's ranch. It was in the side wall of a run off creek bed. There were no other obvious fossils around it, but the wall was crumbling, so it could have washed downstream. The circumference of the main shaft is 20cm while the circumference of the head is 38cm and the length of the fossil is 40cm. I am not very familiar with dinosaurs, but it looks to me like it could possibly be the humerus or the femur of something. Any help would be much appreciated, thank you!

I was exploring a canyon south of Globe, Arizona in the Mescal Mountains where I found two bones in the Devonian Martin Formation, (Frasnian Age, 372-383 mya). Do you agree that they are bones? If so, what type of bones from what creature? I see that the only vertebrates in existence were fish and possibly the earliest tetrapods. See table of Arizona vertebrate fossils found in: DAVID K. ELLIOTT and RONALD C. BLAKEY, “THE PRE-PERMIAN VERTEBRATE RECORD IN ARIZONA”, Heckert, A.B., and Lucas, S.G., eds., 2005, Vertebrate Paleontology in Arizona. New Mexico Museum of Natural History and Science Bulletin No. 29. 19 mm diameter US penney for scale.

Same animal?
