In this study, we reconstructed the paleoecology of five ungulate species common to the area of Toadstool Geologic Park (Sioux County, Nebraska) during the earliest Oligocene (Hyracodon nebraskensis, Subhyracodon occidentalis, Mesohippus bairdi, Merycoidodon bullatus, and Agriochoerus antiquus).
By 35 million BP, Mesohippus was a larger animal and it now had three toes on the front feet, with an enlarged middle toe.
The forest thinned, grass became more prevalent, and Mesohippus appeared.
