Parvodus

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.


 * P. curvidens (Duffin and Thies, 1997), Kimmeridgian, Germany
 * P. pattersoni (Duffin, 1985), Bathonian, England and Scotland
 * P. rugianus (Ansorge, 1990) Berriasian-Valanginian, England, Germany, Denmark and Sweden.

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

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