The bones of an extinct dwarf species of buffalo were recently unearthed on the Philippine island of Cebu.
Dubbed Bubalus cebuensis, the miniature buffalo stood at just more than two feet, three times smaller than today’s domestic buffalo, and weighed a mere 350 pounds. It probably lived during the Pleistocene (Ice Age) or Holocene Epochs, between 10,000 and 100,000 years ago.
Well, forget that last part about the dating. Article says something about 20,000 years ago, but that's it.
