Metalegoceras is an extinct genus of marine cephalopods belonging to the family Schistoceratidae.
This species have been found in the Permian of Australia, Canada, China, East Timor, Indonesia, Kazakhstan, Malaysia, Oman, Russia and United States.
Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America. Though somewhat reminiscent of willows (Salix) in their habitus, they are not particularly close relatives of these.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera. Most spiders in this family build trapdoor burrows. For example, the 20 millimetres (0.79 in) long Sipalolasma builds its burrow in rotted wood, with a hinged trapdoor at each end. The 10 millimetres (0.39 in) long Idioctis builds its burrow approximately 5 centimetres (2.0 in) deep, just below the high tide level, sealing the opening with a thin trapdoor.
Sason is a genus of bark-dwelling brushed trapdoor spiders first described by Eugène Simon in 1887. It is distributed from the Seychelles through India to northern Australia. The closest related genus seems to be the monotypic Paracenobiopelma.
Sason sundaicum is a species of barychelid trapdoor spiders that is found on trees near the sea, usually closer than 100 metres, although distances of up to five kilometres have been observed. They build short nests with two opposing trapdoors, often attached to the bark of living trees, for example Coconut Palms. However, sometimes a nest is built on sides of large boulders. Nests of males are up to two cm long, those of females up to almost three cm. The migid spider Poecilomigas abrahami from South Africa builds very similar nests.
Agathiceras is a subglobose goniatitid from the family Agathiceratidae, widespread and locally abundant in Lower Pennsylvanian to Middle Permian sediments, e.g. the Urals, Sicily, and Texas.
Bathelium is a genus of lichen-forming fungi in the family Trypetheliaceae. The genus was circumscribed in 1803 by Swedish lichenologist Erik Acharius, with Bathelium mastoideum assigned as the type species.
