Trinil Tiger: The Ancestor Of All Known Indonesian Tiger Subspecies?
Panthera tigris trinilensis
Temporal range: Pleistocene
Panthera tigris trinilensis, known as the “Trinil tiger”, is an extinct tiger subspecies dating from about 1.2 million years ago that was found at the locality of Trinil, Java, Indonesia. The fossil remains are now stored in the Dubois Collection of the National Museum of Natural History in Leiden, the Netherlands.
Although these fossils have been found in Java, the Trinil tiger is probably not a direct ancestor of the Javan tiger. The Trinil tiger probably became extinct 50,000 years ago.
The Bali tiger was also not closely related to the Trinil tiger because of their time differences. It is thought that it might have been a bit smaller than the Bengal tigers and similar to the Indochinese tiger’s size.
The Trinil tiger was the oldest form of a tiger that lived 1.66 million years ago in Indonesia, particularly in Java, … according to some zoologists, it could be the ancestor of all known Indonesian subspecies. Perhaps, East Asia was a center of the origin of Pantherinae.
The oldest tiger fossils found in the Javanese Early Pleistocene show that about two million years ago, tigers were already quite common in East Asia. However, the glacial and interglacial climatic variations and other geological events may have caused repeated geographic changes in the area.
Food competition among large carnivores is a major incentive to increase body weight, so that this Pleistocene subspecies’s weight was slightly less than today’s Bengal tigers and weighed about 150 kg.
The reasons behind its extinction are not well understood.
