All genera based on fossil type species belonging to the family Mactridae are alphabetically listed in this work. The oldest records of this family come from Cretaceous deposits of North America. However, from the Paleogene and Neogene, this group of bivalves has been worldwide recorded. An emended diagnosis for each genus is herein provided. In addition to that, type species, type locality and occurrences are included. For each genus, a remark section includes the most recent published taxonomic opinions. Nevertheless, in some cases, new taxonomic decisions have been taken, based on morphological analysis of types. The genera based on extant type species are excluded from this work. A total of 45 genera are herein listed and type material reproduced wherever possible. Ionesimactra “nom. nov.” is proposed as a replacement name for Caspimactra Ionesi (non Caspimactra Ali-Zade and Kabakova). This work constitutes the basis for future revisions related to fossil taxa of the family Mactridae from different regions.
