Ji. Noriega et al., A giant Testudininae tortoise (Chelonii : criptodira) from the Pleistoceneof Corrientes Province, Argentina., AMEGHINIANA, 37(3), 2000, pp. 321-326
Remains of a giant tortoise (Testudininae) were recovered from the Toropi F
ormation (probably middle to upper Pleistocene) in Corrientes Province. A p
artial carapace, an anterior plastral fragment and a left humerus of a sing
le specimen are described herein. This specimen is tentatively referred to
the genus Chelonoidis Fitzinger. Comparisons with additional material from
other localities of the same region suggest a quite diverse giant tortoise
fauna in the Mesopotamic area during the Pleistocene. The Arroyo Toropi spe
cimen is associated with indicators of more arid environments than those pr
evailing at present times in the Mesopotamia.
