The fossil material attributed to bats is exclusively composed of isolated teeth and two nearly complete mandibles. A systematic study by Anthony Ravel Institute of Science of Evolution of Montpellier identified 4 species comprising 1 Definite Rhinolophidae, 2 rhinolophoïdes indeterminate and possible Rhinopomatidae. These are the oldest representatives of current families discovered in Asia. A effet, up to now, the Asian continent was known to have revealed the oldest faunas bats but were mainly composed of extinct archaic families (« Eochiroptera »; Smith et al., 2007; Smith et al., 2012; Tong, 1997).
nyenzo mafuta kuhusishwa na popo ni peke linajumuisha meno wametengwa na mbili mandibles karibu kamili. utafiti utaratibu na Anthony Ravel Taasisi ya Sayansi ya Mageuzi ya Montpellier kutambuliwa 4 aina inahusu 1 Uhakika Rhinolophidae, 2 rhinolophoïdes indeterminate na uwezekano wa Rhinopomatidae. Hizi ni wawakilishi kongwe ya familia sasa aligundua katika Asia. En effet, hadi sasa, Bara la Asia alikuwa anajulikana kwa kuwa wazi kongwe faunas popo lakini walikuwa hasa linajumuisha haiko kizamani familia («Eochiroptera»; Smith et al., 2007; Smith et al., 2012; Tong, 1997).
