Pilmatueia faundezi
(Faúndez's Pilmatué One)Etymology
Pilmatueia is named for the Pilmatué locality in which it was discovered.
The
species epithet,
faundezi, honours Mr. Ramón Faúndez, manager of the Museo Municipal de Las Lajas, for his support of expeditions to the Las Lajas area since 2009.
Discovery
The remains of
Pilmatueia were discovered in the Mulichinco Formation at the Pilmatué locality, 9 km northeast of Las
Lajas, Neuquén Province, Argentina, in 2010, mingled with the remains of the carcharodontosaurid theropod
Lajasvenator, indeterminate diplodocid fossils, and an iguanodontian-like ornithopod that was named
Emiliasaura in 2024.
The
holotype (MLL-Pv-005) is an almost complete back vertebra. The paratype (MLL-Pv-002) is a complete neck vertebra.
Referred material includes another neck vertebra (MLL-Pv-004), an incomplete
neural arch (MLL-Pv-014), the main body of a tail vertebra (MLL-Pv-015), and a complete tail vertebra (MLL-Pv-016). Three articulated neck vertebrae with their respective ribs in position, plus an associated fourth rib, seven back vertebrae with associated ribs, one tail vertebra, a left shoulder blade and the end of a right shoulder blade (MLL-Pv-010) were referred here in 2022.
An isolated discaeosaurid right thigh (MLL-Pv-009) and a natural cast from the inside of a brain-pan—aka "cranial endocast"—(MLL-003) from the same formation might belong to
Pilmatueia.
