Anyone found a good article with data on femur size in bison. Or possibly even comaprasion acorss bison sub species. I found a large femur and am wondering if it is outside of the normal bison bison range. It is 47cm or about 18.5 inches in length.

From the album: BONES
"Horns" (sensu lato) are what bovids have on their heads; "horn" (sensu stricto) is the outer covering or sheath of keratinized skin on bovid horns. Keratin horn does not preserve as a fossil, except perhaps in permafrost. In bovids, horn cores are living bones (that is, they are vascularized and they grow). Horn (keratin) is not vascularized, though new keratin is laid down to keep up with bone growth. Bovid horns are not shed seasonally as with cervid antlers, nor is the keratin sheath shed annually as with the antilocaprid pronghorn antelope. Bone horn cores have internal channels and buttresses, and have no distinct margin between core and bone of the skull. The keratinized skin covering of the horn core is without interior channels or buttresses. The keratin wall tapers to a feather edge and usually shows growth rings on the exterior.© Harry Pristis 2015

Hello I found this sticking out of a wall alongside a creek here in Travis county, Texas. I was hoping to get the specific type of vertebra this is and maybe what it belonged to. Thanks
