Euphemites is an extinct genus of gastropod belonging to order Bellerophontida and family Euphemitidae. [2] They may have been among the first burrowing gastropods. [3]
The Bellerophontidae are an extinct family of specialized globose bellerophontids, Paleozoic and early Triassic mollusks of the class Gastropoda.
Ceolodiscus is a genus in the gastropod family Euomphalidae from the Lower and Middle Jurassic of Europe. The shell is small but stocky; involute or with a slightly protruding spire. Whorls are generally smooth, evenly rounded and slightly overlapping; umbilicus deep, aperture ovate. Is the oldest known holoplanktonic gastropod, thanks to a bilateral symmetrical shells as an adaption to active swimming. Also the most common of the sea snails of the Posidonienschiefer Formation, it is also one of the most varied in size terms, with some of the biggest specimens of snail from the Lower Toarcian know. It has been related to large floating driftwood as one of the primary settlers.
Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically, ethologically, and toponomically, that is, according to their relationship to the surrounding sedimentary layers. Except in the rare cases where the original maker of a trace fossil can be identified with confidence, phylogenetic classification of trace fossils is an unreasonable proposition.
Cyrtoneritimorpha, also Cyrtoneritida, is a clade of fossil sea snails, marine gastropod mollusks within the clade Neritimorpha.
The Aciculidae are a family of minute land snails which have opercula. In other words, Aciculidae are terrestrial operculate gastropods. Even though Aciculidae are land snails, they live in rather wet conditions, among mosses and dead leaves and they have sometimes been described as "winkles come ashore".
Helicoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Eucyclidae is a family of gastropods in the superfamily Seguenzioidea.
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.
Subulitoidea is an extinct superfamily of fossil sea snails, marine gastropod mollusks in the clade Caenogastropoda.
Lanascalidae is an extinct family of sea snails, marine gastropod molluscs.
Quinqueloculina is a genus of foraminifera in the family Miliolidae.
The Kirengellids are a group of problematic Cambrian fossil shells of marine organisms. The shells bear a number of paired muscle scars on the inner surface of the valve.
Subulites is a genus of fossil sea snails, mud-dwelling marine gastropod mollusks known from the early-middle Ordovician, apparently allied with the Caenogastropoda.
