. The fossils are also an evidence that these tigers had large bodies. Their competitor's may have preyed on same individuals which resulted in limiting resources and food competition leading to extinction. The Trinil tiger probably became extinct 50,000 years ago. The Bali tiger was also not closely related to the Trinil because of their time differences. It lived in Indonesia, particularly in Java and Trinil, and according to some zoologists, it could be the ancestor of all known Indonesian subspecies. Perhaps, East Asia was a center of the origin of

. The oldest tiger fossils found in Early Pleistocene Java 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.

Taxonomy

Much research has been done but there is not much knowledge about this subspecies. Scientists have discovered a fossil that is believed to belong to the Trinil tiger. However, there were doubts that the fossil could belong to the Trinil tiger because it was too big to belong to it.
