Discovery
The first remains of
Kelumapusaura were discovered in the Allen Formation (Neuquén Group) at Matadero Hill within Arriagada Farm, 70 km south of General
Roca city, Río Negro Province, north-west Patagonia, Argentina.
The
holotype (MPCN-PV-80) is partial skull, a neck vertebra, a partial block of hip vertebrae (sacrum), part of a tail vertebra and the left side of a breast plate. Paratype specimens PCN-PV-808 (a partial tooth-bearing bone of the right lower jaw), MPCN-PV-809 (hip and tail vertebrae), MPCN-PV-810 (a right shoulder blade), MPCN-PV-811 and MPCN-PV-912 (two hip bones: the left
ilium and right ischium), MPCN-PV-813 (a right thigh), and
MPCN-PV-814 (metatarsal IV) were found 23m from the holotype, mingled with remains of a titanosaur called
Menucocelsior arriagadai.
