Consequently, it did neither aid in understanding phylogenetic relationships of extinct Phocidae, nor in understanding seal diversity in deep time. This urged the reassessment o...

Historically, Monotherium had been one of the few genera of extinct Phocidae (true seals) that served as a wastebin taxon.
