Drulia is a genus of freshwater sponges in the family Metaniidae. [1] [2]
The species of this genus are found in South America. [2]
Drulia contains the following species: [1] [2]
Geodia is a genus of sea sponge belonging to the family Geodiidae. It is the type genus of its taxonomic family.
Polymastia is a genus of sea sponges containing about 30 species. These are small to large encrusting or dome-shaped sponges with a smooth surface having many teat-shaped projections (papillae). In areas of strong wave action, this genus does not grow the teat structures, but instead grows in a corrugated form.
Hymeniacidon is a genus of sea sponges in the class Demospongiae. Some members of the genus are known to be mobile, achieving speeds of between 1 and 4 mm per day.
Isalorhynchus is an extinct genus of hyperodapedontine rhynchosaur from the late Triassic period of Toliara Province, southwestern Madagascar. It is known from the holotype MDE-R18, a nearly complete maxilla and from other specimens from the same locality, Malio River area. It was found in the Makay Formation of the Morondava Basin. It was first named by Eric Buffetaut in 1983 and the type species is Isalorhynchus genovefae. The majority of Isalorhynchus specimens are isolated jaw bones, but two nearly complete skeletons were found in 1998. Langer et al., 2000 concluded that Isalorhynchus is a synonym of Hyperodapedon and referred it to a new species of Hyperodapedon. Whatley, 2005 retained this genus as valid with a description of new materials in her PhD thesis. Montefeltro et al., 2010 and Langer et al., 2010 accepted Isalorhynchus as valid genus.
Chromogisaurus is an extinct genus of saturnaliid sauropodomorph which existed in Argentina during the Late Triassic (Carnian) period. It is from the Cancha de Bochas, Valle Pintado member of the Ischigualasto Formation. It was a herbivore about 2 metres in length, and was optionally quadrupedal.
Howesia is an extinct genus of basal rhynchosaur from early Middle Triassic deposits of Eastern Cape, South Africa. It is known from the holotype SAM 5884, a partial skeleton with palate and partial lower jaws and from two paratypes, SAM 5885 and SAM 5886. It was found in the Burgersdorp Formation of the middle deposits of the Beaufort Group and referred to Subzone B of the Cynognathus Assemblage Zone. It was first named by Robert Broom in 1905 and the type species is Howesia browni, named after Alfred Brown.
Spongilidae is a family of sponges that live in freshwater lakes and rivers. The following genera are recognized in the family:
Radiospongilla is a genus of freshwater sponges in the family Spongillidae. It was defined by Penney and Racek in 1968. The type species is Radiospongilla sceptroides.
Racekiela is a genus of freshwater sponges in the family Spongillidae.
Metaniidae is a family of freshwater sponges, with five genera and 27 species:
Pseudochampsa is an extinct genus of proterochampsid archosauriform known from the Late Triassic (Carnian) Cancha de Bochas Member of the Ischigualasto Formation of San Juan Province, Ischigualasto-Villa Unión Basin in northwestern Argentina. It contains a single species, Pseudochampsa ischigualastensis, originally named as a second species of the closely related Chanaresuchus, based on a fairly complete articulated skeleton and skull. A revision of the remains concluded that it was best to move to species to its own genus, as no traits were found to unite P. ischigualastensis and the type species of Chanaresuchus to the exclusion of other proterochampsids. A phylogenetic analysis places both species in a polytomy with Gualosuchus as the most advanced members of Proterochampsia.
Martín Daniel Ezcurra is an Argentine palaeontologist naming many extinct genera such as Aerotitan, Lophostropheus and Powellvenator.
Anheteromeyenia is a genus of freshwater sponge. It has been recorded in the Nearctic, the Neotropics. This taxon was initially a subgenus of Heteromeyenia when K. Schöder circumscribed it in 1927, but W. M. de Laubenfels made it a genus in its own right in 1936.
Heteromeyenia is a genus of sponges belonging to the family Spongillidae.
Trochospongilla is a genus of sponges belonging to the family Spongillidae.
Metania is a genus of sponges in the family Metaniidae.
Acalle is a genus of freshwater sponges in the family Metaniidae.
Houssayella is a genus of freshwater sponges in the family Metaniidae.
Corvomeyenia is a genus of freshwater sponges in the family Metaniidae.
