Though they haven't become as large as " Taeniolabis ", lambdopsalids were still large by multituberculate standards, the largest species weighting around 30 kg.

In 1996, Kielan-Jaworowska and Bonaparte tentatively identified a lower jaw fragment with a multituberculate-like fourth lower premolar ( p4 ) from Los Alamitos as " Ferugliotherium ".

Several varieties of mammals, such as the multituberculate " Cimexomys " coexisted with dinosaurs in the Two Medicine Formation and the various other formations that make up the Judith River wedge.

Some multituberculates are known to have had omnivorous or animalivorous habits, and although at least some multituberculate faunas became extinct due to competition from rodents early encounters might have looked something like this.
35.
Rodents are thought to have evolved in Asia, where local multituberculate faunas were severely affected by the Cretaceous Paleogene extinction event and never fully recovered, unlike their North American and European relatives.

The species " Tombaatar sabuli " is known from remains found in the Upper Cretaceous Djadokhta Formation of Ukhaa Tolgod, Mongolia . " Tombaatar " was a relatively large multituberculate.
37.
In 2004 and 2007, Kielan-Jaworowska and colleagues aligned the dentary with the multituberculate suborder " Plagiaulacida " because the p4 is rectangular in labial view, not curved as in the suborder Cimolodonta.
38.
The La Colonia Formation also contains dryolestoids, such as " Coloniatherium " and " Reigitherium ", as well as a ferugliotheriid and the putative multituberculate " Argentodites ".
39.
Indeed, this culminated with " Taeniolabis " setting the record for being the largest multituberculate ( and, indeed, non-therian mammal ) of all time, at around 100 kg.

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.
