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