''Paracimexomys'' is a genus of extinct mammals in the also extinct Multituberculata order. ''Paracimexomys'' lived during the Cretaceous period. The few fossils remains come from North America. Some Romanian fossils were also tentatively assigned to this genus, though that classification now seems doubtful. The genus ''Paracimexomys'' ("beside ''Cimexomys''") was named by Archibald J.D. in 1982. ''Paracimexomys'' fossils were originally referred as ''Cimexomys'', until it was realized they were different enough to justify a genus of their own. ==Species== * ''Paracimexomys magister'' also known as ''Cimexomys magister''- Remains were found in the Upper Santonian (Upper Cretaceous) of Utah, USA. The animal probably weighed about 100g when it was alive. * ''Paracimexomys magnus'' also known as ''Cimexomys magnus''- Found in the Campanian (Upper Cretaceous) strata of the Judith River Formation in Montana, USA. * ''Paracimexomys priscus''- Fossil remains were found in the Maastrichtian (Upper Cretaceous) of Hell Creek, Montana. Remains were first found in 1966. The holotype is in the collection of the University of Alberta, where the name ''Cimexomys'' is favoured. Weight is estimated to have been 60g. 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「Paracimexomys」の詳細全文を読む スポンサード リンク
