Valenopsalis
''Valenopsalis'' is an extinct mammal from the Paleocene of North America (more specifically, Puercan-aged deposits in Wyoming, Montana and Saskatchewan. Originally referred to the genus '' Catopsalis'' (''C. joyneri''), it has more recently been moved to its own genus as the former was understood to be a wastebasket taxon. It is currently considered to be the most basal representative of Taeniolabidoidea Taeniolabidoidea is a group of extinct mammals known from North America and Asia.

Taeniolabidoidea
Taeniolabidoidea is a group of extinct mammals known from North America and Asia. They were the largest members of the extinct order Multituberculata, as well as the largest non-therian mammals. '' Lambdopsalis'' even provides direct fossil evidence of mammalian fur in a fairly good state of preservation for a 60-million-year-old animal. Some of these animals were large for their time; '' Taeniolabis taoensis'' is the largest known multituberculate and though smaller, '' Yubaatar'' is the largest known Mesozoic Asian multituberculate.L.

Scientific Reports 5(14950):1-11 Average members of the Taeniolaboidea were about beaver-sized and the largest even reached sizes comparable to the largest beavers like ''Castoroides'', up to about 100 kilograms. The group was initially established as a suborder, before ...
