Resumen:
In this contribution we document the southernmost
and probably the oldest record of the tribe Neuryurini
(Glyptodontidae). The southernmost record of this
tribe outside of Patagonia is Neuryurus sp. from Lujanian
sediments (Luja´n Formation, late Pleistoceneearly Holocene)
at Queque´n Grande River (Buenos Aires Province,
Argentina). The first and only previous record of a specimen
of the Neuryurini in Patagonia was reported from the
upper levels of the Puerto Madryn Formation (Huayquerian
SALMA, late Miocene), exposed in Penı´nsula Valde´s
(Chubut Province, Argentina). The new specimen described
here and assigned to an indeterminate Neuryurini was
recovered at Estancia La Peninsular (Santa Cruz Province,
Argentina). This locality has been recognized in geological
studies as part of the Santa Cruz Formation (Santacrucian
SALMA, late early Miocene), but there have been no
fossils described from this site until now. Therefore, the
new specimen represents, with the two confirmed records
of Glyptodon Owen and Panochthus Burmeister (both from
the Quaternary), the only non-Propalaehoplophorinae
glyptodontids reported for Santa Cruz Province.
