A critical revision of the fossil record, stratigraphy and diversity of the Neogene seal genus Monotherium (Carnivora, Phocidae) [PDF]
, 2018 Historically, Monotherium had been one of the few genera of extinct Phocidae (true seals) that served as a wastebin taxon. Consequently, it did neither aid in understanding phylogenetic relationships of extinct Phocidae, nor in understanding seal ...

Radix entomolaris with “three distal canals:” A rare case report
Indian Journal of Dental Sciences, 2022 The intricate and atypical morphology of mandibular molars makes root canal therapy challenging both in diagnosis and during clinical procedure. The clinician should have knowledge on precise nature of the root canal structure and morphology.
