TL;DR: In 1969, DJ Mulvaney sent me a batch of subfossils excavated by him and his colleagues from caves and rock-shelters in the Makassar region of Sulawesi, and among them are samples from a cave containing examples of Lenomys meyeri, a large-bodied rat endemic to Sulaw Indonesian, and a single right dentary with an intact molar row that is from a smaller-bodied Lenoms, which represents a new species.
Abstract: In 1969, DJ Mulvaney sent me a batch of subfossils excavated by him and his colleagues from caves and rock-shelters in the Makassar region of Sulawesi (Mulvaney and Soejono, 1970). Among them are samples from a cave (Leang Burung 1) containing examples of Lenomys meyeri, a large-bodied rat endemic to Sulawesi, and a single right dentary with an intact molar row that is from a smaller-bodied Lenomys, which represents a new species. The small Lenomys along with specimens of L. meyeri were excavated from a level with a radiocarbon date of 2820 ± 210 BP, and other examples of L. meyeri were found in an underlying stratum dated at 3420 ± 400 BP (Mulvaney and Soejono, 1970: 171).
