''Siamoperadectes'' is a genus of non-marsupial metatherian from the Miocene of Thailand. A member of Peradectidae, it is the first member of its clade known from South Asia, and among the last non-marsupial metatherians. ==Description== The type specimen of ''Siamoperadectes'' is a single third upper molar found in the Li Mae Long Basin, northern Thailand. It displays a rectilenear predilambdodont centrocrista, lacks an hypocone and has a moderately slender lingual part of the molar, all charactertistics that most closely connect it to peradectid metatherians. However, it also displays several unique characteristics: - a deep and narrow protofossa; - very weak conules; - an anteroposteriorly compressed protocone; - a posterior cingulum at the base of the metacone. The molar is quite small, and in life would probably have belonged to a creature about the size of a modern ''Monodelphis'' opossum. Though peradectids have been traditionally considered scansorial, the fact that the relatively closely related herpetotheriids were terrestrial may suggest a similar lifestyle, though the lack of postcranial remains for ''Siamoperadectes'' render this speculation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Siamoperadectes」の詳細全文を読む スポンサード リンク
