Lanthanostegus is an extinct genus of non-mammalian synapsids from the Capitanian Tapinocephalus Assemblage Zone, Koonap Formation (Beaufort Group) of South Africa. The type and the only species is Lanthanostegus mohoii.

Taxonomic history

The animal was named as Lanthanocephalus mohoii by Modesto et al. in 2002 ^[3] but was recombined as Lanthanostegus mohoii in 2003, as the genus Lanthanocephalus was preoccupied by a coral. ^[2]

Phylogeny

The topology follows Duhamel et al. (2024). ^[4]
