Campananeyen fragilissimus
(The Most Fragile Las Campanas Air)Etymology
Campananeyen is derived from "Las Campanas" (for the Barda Atravesada de Las Campanas locality where it was found) and the Mapundungun "n'eyen" (air), referring to the extensive pneumatic (air filled) chambers within the holotype skeleton. The
species epithet,
fragilissimus, means "the most fragile" in Latin, referring to the ilium (a part of the hip) being so thin-walled and fragile with more air chambers than bone.
Discovery
The remains of
Campananeyen were discovered in the Candeleros Formation at the Barda Atravesada de Las Campanas locality on the land of Alfredo Kamman, near Villa El Chocón, Neuquén Province, Argentina, by staff of the Ernesto Bachmann Museum of Villa El Chocón in 2009.
The
holotype (MMch-PV 71) consists of a partial vertebra from the back, hip, and tail, pieces of the ilia (the uppermost and largest of the hip bones), two finger bones, plus a braincase and a jaw bone that were described (but not named) by Carabajal
et al. in 2016.
