Glishades ericksoni

(Hidden in Mud, for Erickson)Etymology
Glishades is derived from the Latin "glis" (mud) and the Greek "hades" (hidden), alluding to its fossils being conceiled in muddy sediment. Hades is also the Greek God of the underworld, metaphorically referring to the world beneath the surface where fossils occur.
The species epithet, ericksoni, honours Dr. Gregory M. Erickson.
Discovery
The remains of Glishades were discovered at the South Milk River locality of the Two Medicine Formation, 30 miles west of Sweetgrass, Glacier County, Montana, USA, by Brown, Kaiser, and Johnson sometime around 1915.
The holotype (AMNH 27414) amounts to a partial left and right premaxillae.
