Paracimexomys fossil map
Where fossils of Paracimexomys have been found, shown on the Earth as it looked about 85 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 85 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Paracimexomys
Paracimexomys is a genus of extinct mammals in the 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 to as Cimexomys, until it was realized they were different enough to justify a genus of their own.
