Orthaulax is an extinct genus of sea snails in the family Strombidae.
Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, commonly called "murexes" or "rock snails".
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may refer generally to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.
Ostrea is a genus of edible oysters, marine bivalve mollusks in the family Ostreidae, the oysters.
Desmostylus is an extinct genus of herbivorous mammal of the family Desmostylidae living from the Chattian stage of the Late Oligocene subepoch through the Late Miocene subepoch and in existence for approximately 21.2 million years.
Buccinum is a genus of medium-sized sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks.
Panopea is a genus of large marine bivalve molluscs or clams in the family Hiatellidae. There are 10 described species in Panopea. Many of them are known under the common name "geoduck".
Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs.
Dinosuchus is a problematic genus of extinct alligatorid crocodylomorph. It was very large compared to other alligatorids, save for the giant caiman Purussaurus and its closest relatives. The genus was first described in 1876 on the basis of a vertebra from the Brazilian Amazon, the type species being named D. terror. In 1921, a new species of Dinosuchus, D. neivensis, was named based on a large mandible that was discovered in Colombia. D. neivensis was later found to be synonymous with both Brachygnathosuchus braziliensis and Purussaurus brasiliensis, being reassigned in 1924 to the senior synonym P. brasiliensis. In 1965, D. terror was proposed to be a nomen vanum.
Diodora is a genus of small to medium-sized keyhole limpet in the family Fissurellidae.
Mesalia is a genus of sea snails, marine gastropod mollusks in the family Turritellidae.
Microstelma is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Zebinidae.
The Cedar District Formation is a geologic formation exposed on Vancouver Island, the Gulf Islands of British Columbia and San Juan Islands of Washington (state). It preserves fossils dating back to the Campanian Epoch of the Cretaceous period. It dates to the lower mid-Campanian.
Glyptoactis is a mostly extinct genus of bivalves in the family Carditidae. They have been recovered from the Castle Hayne Limestone geologic formation in North Carolina and in France.
Carinodrillia fusiformis is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.
Carinodrillia winchesterae is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.
Carinodrillia zooki is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.
