(Brill Academic Publishers, 2017-03)
This study focuses on basking behaviour of Phrynops hilarii in the southernmost population of the species' range. The objective was to determine how environmental features affect the basking behaviour of the species. We ...

Growth dynamics and body size evolution of South American long-necked chelid turtles: a bone histology approach
(Polish Academy of Sciences. Institute of Paleobiology, 2020-06-22)
Among turtles, cases of ?gigantism? occur mostly in pleurodiran Pelomedusoides and cryptodirans, but are infrequentamong pleurodiran chelids, which are mostly small-medium sized turtles. Yaminuechelys spp. are extinct South ...

There are many cases of animals reported in localities away from natural areas of distribution for the species. With respect to native freshwater turtles of Argentina and bordering countries, several populations (and single ...
Giant fossil tortoise and freshwater chelid turtle remains from the middle Miocene, Quebrada Honda, Bolivia: evidence for lower paleoelevations for the southern Altiplano
We describe the first Miocene turtle remains from Bolivia, which were collected from the late middle Miocene (13.18–13.03 Ma) of Quebrada Honda, southern Bolivia. This material includes a large scapula-acromion and fragmentary ...
