They are similar but not exactly the same, namely the part that the arrow points to.

Yes, I see that it is much different in a number of ways. I think this is an artiodactyl, rather than a perissodactyl (horse). I can't determine the size of the bone, so I'm guessing it falls into the deer - cow range.

The end that I showed in the last picture is 2 1/2 inches at the widest point & 1 3/8 at the narrowest. The bone shaft at the narrowest point is 1 5/8 inches X 1 inch. Could this be a bison tibia? I found quite a few bison fossils in that section of the creek. Also this bone looks too large to be from a deer, but my knowledge is very limited.

My best guess, based on the dimensions provided, is domestic cow, Bos.

It is certainly possible that this bone was from a spindle-legged bison; but, again, my best guess is cow.

From what I can tell, the trochlea are at an oblique angle, which means it can only be a tapir or a horse (or rhino, if Miocene). Artiodactyl trochlea are absolutely straight fore and aft.

The plural of "anecdote" is not "evidence".
