Homo floresiensis (pronflɔːr'ɛzi:ˌɛn.sɪs also known as "Flores Man") is an extinct species of small archaic human that inhabited the island of Flores, Indonesia, until the arrival of modern humans about 50,000 years ago.
The remains of an individual who would have stood about in height were discovered in 2003 at Liang Bua cave. Partial skeletons of at least nine individuals have been recovered, including one complete skull, referred to as "LB1".
This hominin was at first considered remarkable for its survival until relatively recent times, initially thought to be only 12,000 years ago. However, more extensive stratigraphic and chronological work has pushed the dating of the most recent evidence of its existence back to 50,000 years ago. The Homo floresiensis skeletal material is now dated from 60,000 to 100,000 years ago; stone tools recovered alongside the skeletal remains were from archaeological horizons ranging from 50,000 to 190,000 years ago.
The first specimens were discovered on the Indonesian island of Flores on 2 September 2003 by a joint Australian-Indonesian team of archaeologists looking for evidence of the original human migration of modern humans from Asia to Australia. They instead recovered a nearly complete, small-statured skeleton, LB1, in the Liang Bua cave, and subsequent excavations in 2003 and 2004 recovered seven additional skeletons, initially dated from 38,000 to 13,000 years ago.
In 2004, a separate species Homo floresiensis was named and described by Peter Brown et al., with LB1 as the holotype. A tooth, LB2, was referred to the species. LB1 is a fairly complete skeleton, including a nearly complete skull, which belonged to a 30-year-old female, and has been nicknamed "Little Lady of Flores" or "Flo". An arm bone provisionally assigned to H. floresiensis, specimen LB3, is about 74,000 years old. The specimens are not fossilized and have been described as having "the consistency of wet blotting paper". Once exposed, the bones had to be left to dry before they could be dug up.
