Postcranial anatomy of Riograndia guaibensis (Cynodontia: Ictidosauria)
(Elsevier France-editions Scientifiques Medicales Elsevier, 2019-04)
Postcranial remains of non-mammaliaform cynodonts provide crucial information documenting the anatomical steps and locomotor advances that led to the mammalian pattern. Here, we present a detailed description of the first ...
Extreme postcranial pneumaticity in sauropod dinosaurs from South America
(Springer Heidelberg, 2012-11)
Birds are unique among living tetrapods in possessing pneumaticity of the postcranial skeleton, with invasion of bone by the lung and air-sac system. Postcranial skeletal pneumaticity (PSP) has been reported in numerous ...
Relationship between myological variables and different take-off and landing behaviours in frogs
(Wiley Blackwell Publishing, Inc, 2019-03-01)
Although landing behaviour in anurans differs significantly among species, a take-off behaviour seems to be largely conserved in the evolution of frogs and toads. The ancestral mode of landing is hypothesized to involve ...
New species of the corumbataia cuestae group (Siluriformes: Loricariidae) from the rio tocantins basin, with comments on its phylogenetic relationships
(2020-01-01)
A new species of Corumbataia is described from Rio Maranhão, Rio Tocantins basin, central Brazil. The new species is distinguished from all congeners by the presence of a small, naked area on snout tip; by having the abdomen ...
New species of the Corumbataia cuestae group (Siluriformes: Loricariidae) from the Rio Tocantins basin, with comments on its phylogenetic relationships
(Soc Brasileira Ictiologia, 2020-01-01)
A new species of Corumbataia is described from Rio Maranhao, Rio Tocantins basin, central Brazil. The new species is distinguished from all congeners by the presence of a small, naked area on snout tip; by having the abdomen ...
A new species of flea-toad (Anura: Brachycephalidae) from southern Atlantic Forest, Brazil
(Magnolia Press, 2016-02-18)
We describe a new species of Brachycephalus that is morphologically similar to the flea-toads B. didactylus, B. hermogenesi, and B. pulex. The new species occurs from the sea level up to 1000 m and it is widely distributed ...
Multiple connections between Amazonia and Atlantic Forest shaped the phylogenetic and morphological diversity of Chiasmocleis Mehely, 1904 (Anura: Microhylidae: Gastrophryninae)
(2019-01-01)
Chiasmocleis is the most species-rich genus of Neotropical microhylids. Herein, we provide the first comprehensive multilocus phylogeny for the genus, including all but 3 of the 34 recognized species and multiple individuals ...
