Coniacian genera

Tylosaurus (; "knob lizard") is a genus of russellosaurine mosasaur (an extinct group of predatory marine lizards) that lived about 92 to 66 million years ago during the Turonian to Maastrichtian stages of the Late Cretaceous. Its fossils have been found primarily around North Atlantic Ocean including in North America, Europe, and Africa.

Xiphactinus (from Latin and Greek for "sword-ray") is an extinct genus of large predatory marine ray-finned fish that lived during the late Albian to the late Maastrichtian. The genus grew up to in length, and superficially resembled a gargantuan, fanged tarpon. It is a member of the extinct order Ichthyodectiformes, which represent close relatives of modern teleosts.

Inoceramus (Greek: translation "fibrous shell" for the fibrous structure of the mineral crystals in the shell) is an extinct genus of fossil marine pteriomorphian bivalves that superficially resembled the related winged pearly oysters of the extant genus Pteria. They lived from the Early Jurassic to latest Cretaceous.

Enchodus (from , 'spear' and 'tooth') is an extinct genus of aulopiform ray-finned fish related to lancetfish and lizardfish. Species of Enchodus flourished during the Late Cretaceous, where they were a widespread component of marine ecosystems worldwide, and there is some evidence that they may have survived to the Paleocene or Eocene; however, this may just represent reworked Cretaceous material.

Gillicus was a relatively small (about long) marine ichthyodectiform ray-finned fish that lived in central North America (Western Interior Seaway), Europe and East Asia, from the late Albian to the early Maastrichtian.

Nipponopterus (meaning "Nippon wing") is an extinct genus of azhdarchid pterosaur that lived during the Late Cretaceous (Turonian to Coniacian ages) in what is now Japan. It is known from a partial cervical (neck) vertebra found in the 'Upper Formation' of the Mifune Group, located in the Kumamoto Prefecture in Kyūshū. The genus contains a single species, Nipponopterus mifunensis, named and described in 2025. It is the first pterosaur to be named from Japan.

Bananogmius is an extinct genus of marine ray-finned fish that was found in what is now North America and Europe during the Late Cretaceous, from the Cenomanian to the Santonian. It lived in the Western Interior Seaway, which split North America in two during the Late Cretaceous, as well as the proto-North Sea of Europe.

Angolasaurus ("Angola lizard") is an extinct genus of mosasaur. Definite remains from this genus have been recovered from the Turonian and Coniacian of Angola, and possibly the Coniacian of the United States, the Turonian of Brazil, and the Maastrichtian of Niger. While at one point considered a species of Platecarpus, recent phylogenetic analyses have placed it between the (then) plioplatecarpines Ectenosaurus and Selmasaurus, maintaining a basal position within the plioplatecarpinae.

Phylloceras is an extinct genus of ammonoid cephalopods belonging to the family Phylloceratidae. These nektonic carnivores lived from Early Jurassic (Hettangian age) to Late Cretaceous (Maastrichtian age) (from 201.30 to 66.043 Ma).

Baikuris is an extinct genus of ant in the Formicidae subfamily Sphecomyrminae, and is currently placed in the tribe Sphecomyrmini. The genus contains four described species: the type species Baikuris mandibularis, along with Baikuris casei, Baikuris maximus, Baikuris mirabilis, B. ocellantis.

Puzosia is a genus of desmoceratid ammonites, and the type genus for the Puzosiinae, which lived during the middle part of the Cretaceous, from early Aptian to Maastrichtian (125.5 to 70.6 Ma). Sepkoski defines the range from Albian to Santonian. The generic name comes from the Serbian words "Puž" (snail) and "oce/ose" (axis), gaining its name from the shell's snail-like appearance.

Anagaudryceras is an extinct genus of ammonite from the later Cretaceous belonging to the Ammonoidea family Gaudryceratidae. Anagaudryceras has a moderately involute shell with a deep umbilicus and strongly ribbed outer whorl. Ribs are thick and rounded and cross over the venter uninterrupted.

Tsogtopteryx () is an extinct genus of azhdarchid pterosaurs known from the Late Cretaceous Bayanshiree Formation of Mongolia. The genus contains a single species, Tsogtopteryx mongoliensis, known from most of a cervical (neck) vertebra. It was closely related to Hatzegopteryx, and coexisted with Gobiazhdarcho, another azhdarchid more closely related to Quetzalcoatlus.

Gobiazhdarcho () is an extinct genus of azhdarchid pterosaurs known from the Late Cretaceous Bayanshiree Formation of Mongolia. The genus contains a single species, Gobiazhdarcho tsogtbaatari, known from a three cervical (neck) vertebrae. It was closely related to Quetzalcoatlus and coexisted with Tsogtopteryx, another azhdarchid more closely related to Hatzegopteryx.
