There's a new fossil ungulate-related article available online if anyone is interested: Nicolás R. Chimento; Federico L. Agnolin (2020). Phylogenetic tree of Litopterna and Perissodactyla indicates a complex early history of hoofed mammals. Scientific Reports 10 (1): Article number 13280. doi:10.1038/s41598-020-70287-5. The perissodactyl affinities of litopternans have been previously suggested by DNA-based analyses, but the paper by Chimento and Agnolin is the first morphology-based cladistic analysis to support a relationship between Perissodactylia and Litopterna. Moreover, some families assigned to the polyphyletic group "Condylarthra" are recovered as related to Perissodactyla, while the condylarth family Phenacodontidae is recovered along with Pleuraspidotheriidae as sister to Afrotheria (which includes elephants, aardvarks, hyraxes, elephant shrews, and sirenians).

I found this tooth in the overburden sight at my work. I actually found this tooth first, and went to grab a survey flag to mark the pile. On the way I found the shark tooth i just shared in an other post. It was an exciting day. Anyway, from looking at the molar patterns of other horse tooth fossils I think that this is a three-toed horse (Perissodactyla Miohippus ?). Judging from what I think is wear on the tooth ridges, I would hazard a guess that the horse was an old timer? While I personally am not fond of horses, it was really nice to have pieces that I could clearly identify for once, instead of various fragments of a fossil jigsaw puzzle.
