Abstract

Five fossil endocarps were collected from late Miocene fluvial deposits in a commercial sandpit in Northeastern Thailand. The endocarps were studied with light microscopy and scanning electron microscopy (SEM) and compared with recent and fossil endocarps. We conclude that the endocarps are Parinari (Chrysobalanaceae) and propose two new species, P. hilliana and P. khoratensis. These provide the first record of Parinari fruits from Asia and the Pacific region and indicate that the genus was already pantropical by the Miocene with previous reports of Miocene Parinari endocarps from Africa (Ethiopia) and the Neotropics (Panama).

泰国东北部新近系Parinari（金龟子科）的内果皮

在泰国东北部的一个商业沙坑中，从中新世晚期的河流沉积物中收集了五个内果皮化石。利用光学显微镜和扫描电子显微镜（SEM）对内果皮进行了研究，并与近年来的内果皮和化石进行了比较。我们认为内果皮为金龟子科植物Parinari，并提出了两个新物种，即P.hilliana和P.khoratensis。这些提供了来自亚洲和太平洋地区的Parinari果实的第一个记录，并表明该属在中新世已经是泛热带的，此前有来自非洲（埃塞俄比亚）和新热带（巴拿马）的中新世Parinari内果皮的报道。
