matgerke Posted February 20, 2018 Share Posted February 20, 2018 I found this in a river in Virginia -- miocene Yorktown Formation. Does this look like a miocene horse? Maybe it's a modern horse tooth that got washed into the river? Any help from the experts appreciated! Matt Link to post Share on other sites
Coco Posted February 20, 2018 Share Posted February 20, 2018 The little vertical lines on the 2nd photo add in the elements of determination leading to the horse. Coco Link to post Share on other sites

Fruitbat Posted February 20, 2018 Share Posted February 20, 2018 +1 for 'modern' Equus. The presence of an attached protocone is a bit of a giveaway. -Joe 2 Link to post Share on other sites
Harry Pristis Posted February 20, 2018 Share Posted February 20, 2018 I agree. It's an equus M1 or M2. Just a cautionary note: An attached protocone is not always indicative of Equus, as in the attached images of Dinohippus and Calippus below. 2 Link to post Share on other sites
matgerke Posted February 21, 2018 Author Share Posted February 21, 2018 Thanks for the wisdom! Any thoughts on how I can distinguish between a modern horse and a pleistocene horse? Or should I just assume it's modern? Link to post Share on other sites
