Biology

The Aldabra horned terrestrial crocodile (Aldabrachampsus dilophus) was probably around 2 meters long at maturity (Brochu et al. 2010). However, more recently reported crocodilian material that may be attributable to this species is larger than previous estimates for the species (Scheyer et al. 2018).
