I hope to see someone else's fossil bones here. How 'bout it?
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).
Ok, here is what I've got. Small mammal, and large reptile...
Here is what I have found, all of the large "dino" bones were found in a field by me when I was 6 years old. My grandfather had plowed it, and they were just sticking up everywhere, and I went to town! I wish we still owned the land, because I would be back there all the time! Only ones I can identify are the turtle scoots.
sorry this pic is blurry, it is a broken tooth(base and tip broken), I was trying to show the serration on the sides of it!
This set of small mammal bones came from a property that is a friend of my mother's. I need to go back there someday, on another property nearby, the U of M students found a complete skeleton of a five toed horse! Not sure what these are from though.
Someday I'll have to box these up and take them to the U of M to find out what they all are.

Wow! So many really amazing fossilized bones I'm not sure if this is worthy but I hope someone may find it interesting. Found in Northern Minnesota.
Maybe some suggestions as to what this may be. Magnetized all around except where there appears to be bone.
Thanks for the look.
That's a reasonable guess . . . the hyperostosis of the bone (injury-generated?) gives it a very strange aspect indeed. But the bone is just a rhino metacarpal, probably from Teleoceras sp.
