A study recently published in Scientific Reports details the discovery of a previously unidentified ancient alligator species found in Thailand, which shares close evolutionary ties with the Chinese alligator (Alligator sinensis). Researchers Gustavo Darlim, Márton Rabi, Kantapon Suraprasit, Pann
from Thailand. This groundbreaking research unveils unique skull characteristics and offers a deeper dive into the evolutionary lineage of Asian alligators.details the discovery of a previously unidentified ancient alligatorResearchers Gustavo Darlim, Márton Rabi, Kantapon Suraprasit, Pannipa Tian, and their team identified the new species by examining a nearly complete fossilized skull — which they date to younger than 230,000 years old — from Ban Si Liam, Thailand.
They propose that the two species are closely related and may have shared a common ancestor in the lowlands of the Yangtze-Xi and Mekong-Chao Phraya river systems. They speculate that increases in the elevation of the southeastern Tibetan Plateau between 23 and five million years ago may have led to the separation of different populations and evolution of two separate species.
