Scrobicularia is a genus of bivalve mollusc belonging to the family Semelidae. [2] [3] It is sometimes placed in its own family, Scrobicularidae. [1] [4]
There are two recognised species: [2]
However, ITIS only recognizes Scrobicularia caduca. [5] There are also names with uncertain status: [2]
Lepisosteus is a genus of gars in the family Lepisosteidae.
Sea spiders are marine arthropods of the order Pantopoda, belonging to the class Pycnogonida, hence they are also called pycnogonids. They are cosmopolitan, found in oceans around the world. The over 1,300 known species have leg spans ranging from 1 mm (0.04 in) to over 70 cm (2.3 ft). Most are toward the smaller end of this range in relatively shallow depths; however, they can grow to be quite large in Antarctic and deep waters.
Megalosaurus is an extinct genus of large carnivorous theropod dinosaurs of the Middle Jurassic Epoch of southern England. Although fossils from other areas have been assigned to the genus, the only certain remains of Megalosaurus come from Oxfordshire and date to the late Middle Jurassic.
Pholidoteuthis is a genus of squid in the monotypic family Pholidoteuthidae, comprising at least two species. The defunct genus Tetronychoteuthis was previously incorporated into Pholidoteuthidae based upon a singular taxon known as Tetronychoteuthis massyae. Following the discovery of Pholidoteuthis boschmai in 1950, T. massaye was placed into Pholidoteuthis, with Tetronoychoteuthis considered a nomen dubium. P. boschmai is now considered a junior synonym of P. massyae.
Titanosaurus is a dubious genus of sauropod dinosaurs, first described by Richard Lydekker in 1877. It is known from the Maastrichtian Lameta Formation of India.
Scrobicularia plana, the peppery furrow shell, is a bivalve mollusc belonging to the family Semelidae.
Cetiosaurus meaning 'whale lizard', from the Greek keteios/κήτειος meaning 'sea monster' and sauros/σαυρος meaning 'lizard', is a genus of herbivorous sauropod dinosaur from the Middle Jurassic Period, living about 168 million years ago in what is now Britain.
Szechuanosaurus is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian-?Tithonian. Its type species is based on several undiagnostic teeth from the Kuangyuan Series. Additional possible specimens of Szechuanosaurus were also reported from the Kalaza Formation, also located in China.
Mandschurosaurus is an extinct genus of hadrosaurids based on material from the Late Cretaceous of China and possibly also the Early Cretaceous of Laos. It was the first dinosaur genus named from China.
Pinnoctopus is a genus of octopuses in the family Octopodidae. It is of doubtful validity.
Ranitomeya rubrocephala is a species of frog of doubtful taxonomic status in the family Dendrobatidae.
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.
The Semelidae are a family of saltwater clams, marine bivalve molluscs in the order Cardiida.
Okenia is a genus of colorful sea slugs, specifically of dorid nudibranchs, marine gastropod mollusks in the family Goniodorididae.
Trochosuchus is a dubious genus of therocephalian therapsid from the middle Permian (Capitanian) of South Africa based on a weathered and poorly preserved undiagnostic fossil of a lycosuchid therocephalian. It includes the type and only species, T. acutus. Trochosuchus was named by palaeontologist Robert Broom in 1908 based on its supposedly unique proportions of the simulatenous 'double' functional canines thought to be characteristic of lycosuchids, with the pair in front being noticeably smaller than the second pair behind.
Fusus is a genus of small to large sea snails, marine gastropod molluscs in the family Fasciolariidae, the spindle snails and tulip snails.
Cocculina is a genus of sea snails, deep-sea limpets, marine gastropod mollusks in the family Cocculinidae.
Phyllonotus is a genus of medium to large sized predatory sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, the murexes or rock snails.
Cythara is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae.
Aplustrum is a genus of gastropods belonging to the family Aplustridae.
