The Penghu fauna was discovered in 1975 when it was fished from the bottom of the Penghu waterway. In terms of dating, the Penghu fauna dates back to about 40,000 to 10,000 years ago, belonging to the late Pleistocene. At this time, it was the Ice Age, and the sea level in the Taiwan Strait dropped by more than 50 meters, so the Taiwan Strait emerged from the sea. And became a temperate prairie. Bubalus teilhardi was a large buffalo at that time. It has become extinct. Currently, only the fossils remain for collection and research. This is a large type of buffalo. Bubalus teilhardi in Taiwan's Penghu Waterway can only be found by salvaging from fishing boats. The main fauna of these Penghu waterways sank to the bottom of the sea at the end of the Ice Age. This group of Bubalus teilhardi includes Atlas & Axis, which happens to be a group, and the degree of mineralization is not bad. Desalination and cleaning have been done. Collectors who like mammal bones can refer to the collection.
