Bubalus cebuensis

The Cebu tamaraw (Bubalus cebuensis) is a fossil dwarf buffalo discovered in the Philippines, and first described in 2006.

Large contemporary domestic water buffalo stand 2 m (roughly 6 ft) at the shoulder and can weigh up to 1 tonne (around 2,000 lb), B. cebuensis would have stood only 75 cm (about 2 ft 6 in) and weighed about 150 to 160 kg (around 300 lb), smaller than another dwarf species B.

[1][2] The fossil specimen is likely Pleistocene or Holocene in age.

[1] The fossil was discovered in a horizontal tunnel in soft karst around 50 m elevation in K-Hill near Balamban, Cebu Island, the Philippines, by mining engineer Michael Armas.

[3] The fossil was donated to America's Field Museum, where it stayed unanalyzed for almost 50 years.
