Systematics and dental system reconstruction of the durophagous chondrichthyan Lagarodus JAEKEL, 1898

Oleg A. Lebedev


The type species of the Carboniferous chondrichthyan genus Lagarodus JAEKEL, 1898 is changed to Psammodus specularis TRAUTSCHOLD, 1874 because of an identification error in TRAUTSCHOLD (1874). Five morphotypes: angustus, specularis, cubicus, accessory, and orobranchial are recognised. Tooth morphology, configuration of wear surfaces, growth traces on the basal surface and comparison with extant analogues were used to reconstruct the dentition.
