Aquilarhinus palimentus
(Shovel-Chinned Eagle-Nose)Etymology
Aquilarhinus is derived from the Latin "aquila" (eagle) and the Greek "rhinus" (nose). The
species epithet,
palimentus (pal-ih-MEN-tus), is derived from the Latin "pala" (shovel) and
"mentus" (chin).

Discovery
The first remains of
Aquilarhinus were discovered in the lower shale member of the Aguja Formation on the western flank
of Rattlesnake Mountain, south-western corner of Big Bend National Park, Brewster County, south-western Texas, USA, in 1983, by Thomas Lehman, N. LaFon and Kyle Davies. In 1999, Jonathan Wagner and Lehman continued excavation of the site, collecting additional elements.
The
holotype (TMM 42452-1) is a partial skull, parts of three neck vertebrae and two neck ribs, fragments of the pelvic girdle, an almost complete left hand, a partial ankle, one toe bone, and four claws.
Preparator
