Chelus is a genus of large freshwater turtles found in tropical South America. Formerly considered to be a monotypic genus,[3] it now consists of two extant species after Chelus orinocensis was identified in 2020 from a genetic analysis.[4]
Species
[edit]There are two extant recognized species in this genus[3][5] and one extinct species:[1]
- Chelus fimbriatus – Amazon mata mata
- Chelus orinocensis – Orinoco mata mata
- †Chelus colombianus – Columbian mata mata (Late Miocene) [6]
