A partial deciduous premolar from a gomphothere is reported from the Late Miocene Eastover Formation in New Kent County, Virginia. This represents the first definitive occurrence of a terrestrial mammal from the Eastover Formation.
Gomphotheres are now known from nearly every marine formation from the Middle Miocene to the Early Pliocene along the middle Atlantic Coastal Plain. Gomphotheres are typically associated with more open habitats, but floral data suggests that the region transitioned from warmer, more forested conditions in the Middle Miocene to heterogeneous conditions in the Late Miocene. The persistence of gomphotheres throughout this interval suggests that substantial open habitats were present along the Coastal Plain from the Middle Miocene to at least the Early Pliocene.
