Palmerella is a genus of prehistoric sea snails, marine gastropod mollusks in the family Turritellidae.
Species within the genus Palmerella include:
Volutidae, common name volutes, are a taxonomic family of predatory sea snails that range in size from 9 mm to over 500 mm. They are marine gastropod mollusks. Most of the species have no operculum.
Elimia is a genus of freshwater snails with an operculum, aquatic gastropod mollusks in the family Pleuroceridae. Various species are found in creeks throughout much of the eastern and central United States and the Great Lakes region of Canada. Fossils have been found across the whole of the North American continent, including from the Paleocene of Mexico and the Eocene of California. They were formerly included in the genus Goniobasis, together with the western Juga species.
Thiaridae, common name thiarids or trumpet snails, is a family of tropical freshwater snails with an operculum, aquatic gastropod mollusks in the superfamily Cerithioidea.
Turritellidae, with the common name "tower shells" or "tower snails", is a taxonomic family of small- to medium-sized sea snails, marine gastropod molluscs in the Sorbeoconcha clade.
Scaphander is a genus of sea snails, marine gastropod molluscs in the family Scaphandridae, the canoe bubbles.
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time.
Conorbis is an extinct genus of sea snails, marine gastropod mollusks in the family Conorbidae.
Sediliopsis is a genus of sea snails, marine gastropod mollusks in the family Pseudomelatomidae.
Cochlespira is a genus of sea snails, marine gastropod mollusks in the family Cochlespiridae.
Athleta is a genus of sea snails, marine gastropod mollusks in the family Volutidae.
Exilia is a genus of sea snails in the family Ptychatractidae.
Potamides is a genus of prehistoric sea snails, marine gastropod mollusks in the family Potamididae.
Calyptraea, commonly known as the Chinese hat snails is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, a family which contains the slipper snails or slipper limpets, cup-and-saucer snails, and Chinese hat snails.
Ecphora is the common name for a group of extinct predatory marine gastropod mollusks within the family Muricidae, the rocks snails or murexes. The common name is based on the first officially described genus, Ecphora. The entire lineage of these ocenebrinid murexes are descended from the Eocene murex, Tritonopsis. Ecphoras were indigenous to the North American Eastern Seaboard, being found in marine strata from the Late Eocene until their extinction during the Pliocene. Many ecphora species are important index fossils.
Laevicardium, common name "egg cockles", is a genus of saltwater clams or cockles, marine bivalve molluscs in the family Cardiidae, the cockles. They are unusual among the cockles in that they have smooth, rounded, "egg-like" valves.
This list, 2014 in molluscan paleontology, is a list of new taxa of ammonites and other fossil cephalopods, as well as fossil gastropods, bivalves and other molluscs that have been described during the year 2014.
Crommium is an extinct genus of sea snails, marine gastropod molluscs in the family Ampullinidae.
Babibasiliscus is an extinct genus of casquehead lizard that lived in what is now Wyoming during the early Eocene, approximately 48 million years ago. The genus is known from a single species, Babibasiliscus alxi, which was named by paleontologist Jack Conrad in 2015 on the basis of a fossilized skull from the Bridger Formation in the Green River Basin. The name Babibasiliscus comes from the Shoshoni word babi, meaning "older male cousin", and Basiliscus, a modern-day genus of casquehead lizards. The specimen is undeformed and nearly complete except for the tip of the snout and the top of the skull, making it unclear whether the distinctive bony crest of living corytophanids was present in prehistoric relatives like Babibasiliscus. The skull is about 42 millimetres (2 in) in length and the entire body is estimated to have been about 0.6 metres (2 ft) long. Bones on the right side of lower jaw of the specimen are thickened and fused together, suggesting that the jaw had broken and healed when the animal was alive.
† Potamides archiaci is an extinct species of sea snail, marine gastropod molluscs in the family Potamididae.
Cypraeorbis is an extinct genus of sea snails, marine gastropod mollusks in the subfamily Cypraeinae of the family Cypraeidae.
