[6] These small multituberculates were named by Rădulescu R. and Samson P. in 1996, who stated they Recent studies have favoured a position close to Taeniolabidoidea.

[6] A 2021 study found them to be the amongst the most basal members of Cimolodonta, more derived only than Bryceomys, and they probably originated from an eobaatarid-like ancestor.

In Barbatodon this distribution is more similar to that seen in shrews as opposed to the condition seen in rodents, and suggests insectivore habits.

This is a unique evolutionary route taken in the isolation of their island environment, almost entirely deprived of competing mammals, and inadvertently resulted in their survival across the KT event.

For a brief period of time these were among the most common mammals in Europe, but by the Late Paleocene the arrival of other multituberculate groups from North America brought a quick decline, culminating in its extinction at the PETM.
