A nearly complete fossil skull of short-finned pilot whale, Globicephala macrorhynchus, was dredged from the sea bottom in Penghu Channel, Taiwan Strait. This fossil short-finned pilot whale resembles extant Globicephala macrorhynchus with respect to the morphological characteristics on the skull. This fossil evidence can be inferred that the paleoenvironmental changes in marine and terrestrial habitats in the area of Penghu Channel in the Late Pleistocene.

Hokutolite is a variety of barytes of deposited Barite (BaSO4) by very acid hot springs. Generally it also contains minor strontium and minute traces of radium, marking a recent deposit. Hokutolite is mineral of very rare occurrence worldwide. It crystallizes precipitatedly from hot spring water of geothermal valley at Hokuto (Beitou). Hokutolite is the only one mineral named after a place of Taiwan.

Glaucophane schist was metamorphic rock formed in the low-temperature and high-pressure environment, its protolith was mainly basic volcanic rock. It was formed by the high-pressure and low temperature regional metamorphism, indicating that the Pre-Pacific oceanic plate subducted toward west of the Eurasian plate.

The type of specimen was named by Tien et al. in 1975, and preserved in the collections of NMNS in 1989. Swinefordite is a hydrated clay mineral. These two specimens were collected from Foote Quarry, Cleveland County, NC, USA. One shows a stable phase of dehydration; the other unstable jelly phase of hydration.

Native gold is the main source of gold. In Taiwan, Chiufen-Chinkuashih area was well known for the high quality and high quantity of its native gold. In the past, it had the largest production in the Far East area and was one of the important suppliers of gold in global markets.

This skull of woolly mammoth was recovered from Siberia’s permafrost

This skull of Bubalus teilhardi was recovered by a fishery boat during trawling operations in the Penghu Channel between the Penghu Archipelago and the main island of Taiwan in the Taiwan Strait. Bubalus teilhardi had its origin in the Middle Pleistocene of northern China, from where it migrated to Taiwan by way of the land bridge between Taiwan and mainland China during the Glaciation in the Late Pleistocene.

This partial skull with both right and left upper molars of Palaeoloxodon huaihoensis was recovered from the Penghu Channel. Palaeoloxodon huaihoensis once lived around Huaiho River, northern China in Middle Pleistocene. The Taiwan strait were transformed to exposed shelf due to the sea level dropped by glacial advance. The new land can be inferred to have allowed large mammals, such as Palaeoloxodon huaihoensis to migrate, explore and inhabit it.

This deer skull with nearly complete antler belongs to Cervus sp. which is dominant in fossil amount in Cho-Chen fauna in the Middle Pleistocene.
