Mexidracon longimanus
(Mexican Dragon wwith Long Hands)Etymology
Mexidracon is derived from "Mexi" (referring to Mexico) and the Greek "drak?n" (dragon).
The
species epithet,
longimanus, is derived from the Latin "longus" (long) and "manus" (hand).
Discovery
The remains of
Mexidracon were discovered in the Cerro del Pueblo Formation (Difunta Group) at the Loma Prieta locality, near the town of Porvenir de Jalpa, in the General Cepeda Municipality of Coahuila, Mexico, by Professor Claudio de León-Dávila in 2014. After
Paraxenisaurus (Serrano-Brañas
et al., 2020),
Mexidracon is the second ornithomimosaur to be named from the Cerro del Pueblo formation, but the first ornithomimid formally described from Coahuila.
The
holotype (BENC 32/2-0001) includes back, hip and tail vertebrae, chevrons, a left upper arm and three hand bones, partial pelvic girdles, a complete left and partial right thigh, a complete left and partial right shin, part of a calf, five foot bones, and four toe bones.
