Justin Blake Posted July 23, 2018 Share Posted July 23, 2018 In an old collection I found this small tibia. It is missing the proximal end. I believe this fossil came from Lower Snake Creek making it Miocene. I have no idea what this would have been from. Ruler in pictures is in inches.

someonefinally Posted July 23, 2018 Share Posted July 23, 2018 Perhaps some kind of equus(?) Tapir is a possibility with the location. Link to comment Share on other sites More sharing options...

siteseer Posted July 23, 2018 Share Posted July 23, 2018 2 hours ago, someonefinally said: Perhaps some kind of equus(?) Tapir is a possibility with the location. It's too old to be Equus but possibly a three-toed horse or even rhino. Tapir is a possibility but they weren't as common as horse and rhino. I have seen Lower Snake Creek teeth and bones (Early Miocene - Hemingfordian, I think). I think that's where you can get the earliest Merychippus or whatever the new name is (some species once within Merychippus have been assigned to different genera). 2 Link to comment Share on other sites More sharing options...
Justin Blake Posted July 25, 2018 Author Share Posted July 25, 2018 (edited) Thank you for your replies. I thought the three-toed-horse would have a little more "tilt" to the depressions in the articular surface where it articulates with the astragalus. This tibia doesn't have any tilt. To see what I mean, look at the modern horse tibia below. Oddly, this one looks most like the modern domestic goat (as seen below).

fossillarry Posted August 3, 2018 Share Posted August 3, 2018 It's not a horse, it's from one of the small Miocene artiodactyles like Merycodus. Probably to small to be a dromomerycid. 1 Link to comment Share on other sites More sharing options...
