Extension of the geographical distribution of Schneider’s dwarf Caiman, Paleosuchus trigonatus (Schneider, 1801) (Crocodylia: Alligatoridae), in the Amazon–cerrado transition, Brazil

Abstract

We present new records of occurrence of Schneider’s Dwarf Caiman, Paleosuchus trigonatus and extend its geographical distribution. Eight individuals were caught in the following locations: Sangue River, in the municipality of Campo Novo dos Parecis, Claro River and Marapi River, in the municipality of São José do Rio Claro, and tributaries of the Juruena River, in the state of Mato Grosso, Brazil. These records extend the geographical distribution of the species nearly 500 km south of the limit given in published range maps.
