Bagualia alba
(Early Wild Horse)Etymology
Bagualia is derived from the Spanish "Bagual" (Wild Horse) for the Bagual Canyon site where its fossils were found.
The
species epithet,
alba, means "dawn" in Spanish and alludes to
Bagualia's early age.
Discovery
The remains of
Bagualia were discovered in the Cañadón Asfalto Formation at Bagual Canyon, 5 km south of Cerro Cóndor, Chubut, Argentina, by an international team of researchers led by Diego Pol in 2007.
The
holotype (MPEF PV 3301) is the rear half of a skull found in articulation with seven neck vertebrae.
Referred material from the same quarry, representing three individuals based on upper arm count, covers nearly the full skeleton of
Bagualia.
Preparators
Personnel of the Museo Paleontológico Egidio Feruglio (MPEF), Chubut, Argentina.
