Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.

Batrachosaurus is an extinct genus of prehistoric brachyopoid amphibian that lived in Germany during the Middle Triassic (Ladinian). The genus was named by Joseph Fitzinger in 1837 and the type species, B. jaegeri, was named three years later in 1840. It may have been the same animal as Mastodonsaurus.
Crinodon is an extinct genus of microsaur within the family Tuditanidae. The type and only species C. limnophyes was found in Carboniferous deposits of Nyrany and described by M. C. Steen in 1938 as Ricnodon limnophyes. It was assigned to the new genus Crinodon by R. L. Carroll and P. Gaskill in 1978.
Anagyrus is a large genus of parasitic wasps from the family Encyrtidae. Anagyrus is distributed throughout the world. A subgenus of Anagyrus is known as Nesoanagyrus
Equus alaskae was a Pleistocene species of horse, now extinct, that inhabited North America.
Ablerus is the only genus in the family Azotidae. The genus was created by the American entomologist Leland Ossian Howard in 1894 for the species named in that year by William Harris Ashmead as Centrodora clisiocampae. The genus Azotus was synonymized with Ablerus by Alexandre Arsène Girault in 1913 and Hyatt synonymized Myocnemella with Ablerus in 1994, leaving Ablerus as the sole genus within the subfamily Azotinae. Azotinae was elevated in rank in 2013 to become the monotypic family Azotidae.
