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).
