Parvodus is an extinct genus of hybodont, known from the Mesozoic era.

Species

The initial study naming the genus considered 3 species valid, which were originally placed in Lissodus. [1]

The paper also noted a possible record is known from the Sinemurian of England. [1]

Some later studies also included the species Parvodus heterodon (Patterson, 1966) from the Early Cretaceous of England in the genus, [2] though other studies have included this species in the genus Polyacrodus . [3] Some studies have also included the species "Hybodus" parvidens Woodward, 1916, from the Early Cretaceous of Europe and North America within Parvodus, [4] though again this species has also been assigned to Polyacrodus. [3] [5] A 2023 paper assigned the newly described species P. huizodus from the Early Triassic of China to the genus. [4] The species Parvodus celsucuspus Rees et al., 2013 has been reported from the Early Cretaceous of England and France. [6] [7] A single tooth of Parvodus sp. has also been reported from the Upper Cretaceous (Campanian) of France. [8]
