However, more recent research restores its close relationship with Alouatta. The postcranial morphology of Paralouatta suggests that it was partly terrestrial, and a likely example of island gigantism.
The study suggests that Paralouatta, a primate species, had a connection to Alouatta, possibly due to shared ancestry or ecological factors. Its postcranial structure indicates a partially terrestrial lifestyle, which could have contributed to its large size in isolated islands.
