Amphipora is an extinct genus of sponges, and type genus of the extinct family Amphiporaidae. Species are known from the Silurian to Devonian, over much of the northern hemisphere. [1]
The calcareoussponges are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate, in the form of high-magnesium calcite or aragonite. While the spicules in most species are triradiate, some species may possess two- or four-pointed spicules. Unlike other sponges, calcareans lack microscleres, tiny spicules which reinforce the flesh. In addition, their spicules develop from the outside-in, mineralizing within a hollow organic sheath.

Siphonia is a genus of extinct hallirhoid demosponges of the Lower and Upper Cretaceous, from about 125 to 66 million years ago. They lived in the Western Tethys Ocean, in what is now Europe.
The taxonomy of commonly fossilized invertebrates combines both traditional and modern paleozoological terminology. This article compiles various invertebrate taxa in the fossil record, ranging from protists to arthropods. This includes groups that are significant in paleontological contexts, abundant in the fossil record, or have a high proportion of extinct species. Special notations are explained below:
Exovasa is an extinct genus of sea sponge in the family Guadalupiidae, that existed during the Permian Period in what is now Texas, United States. It was named by Robert M. Finks in 2010, and the type species is Exovasa cystauletoides.
Incisimura is an extinct genus of sea sponges in the family Guadalupiidae, that existed during the Permian period in what is now Texas, United States. It was described by Robert M. Finks in 2010, and the type species is Incisimura bella.
Guadalupia is an extinct genus of sea sponges. It includes a number of extinct species including: Guadalupia auricula, G. cupulosa, G. ramescens, G. microcamera, and G. vasa.
Cystothalamia is an extinct genus of sea sponges in the family Guadalupiidae that existed during the Permian and Triassic in what is now Austria, Hungary, Slovenia, Tajikistan, Croatia, Iran, Italy, Russia, Thailand, Tunisia, the United States, and Venezuela. It was described by G.H. Girty in 1909, and the type species is Cystothalamia nodulifera.
Peronidella is an extinct genus of Calcareous sponges found in marine sedimentary rocks dated between the Devonian and the Cretaceous periods.
Plocoscyphia is an extinct genus of sea sponges belonging to the family Callodictyonidae.
Turonia is an extinct genus of sea sponges belonging to the class Demospongiae.
Clarkina is an extinct genus of conodonts. It is considered to be an offshore, outer shelf or basinal, deep-water taxon.
Cribrospongia is an extinct genus of prehistoric sponges in the family Cribrospongiidae. The species C. elegans is from the Jurassic period and has been found in Germany.
Cryptophragmus is an extinct genus of sponges in the extinct family Aulaceratidae. Species are from the Ordovician of Australia, Canada (Ontario), China and the United States.
Protomonaxonida is an extinct order of sea sponges. It is a paraphyletic group gathering the most ancient species from the Burgess Shale to modern sponges.
Eodictyonella is a genus of rhynchonelliform brachiopods belonging to the extinct class Chileata. It is characterised by a non-strophic shell covered by a net-like ornament. Like in most chileates, the perforation in the umbonal region of the ventral valve is covered by a colleplax. Eodictyonella is known from the Ordovician to the Lower Devonian.
Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area is a 2,410-square-kilometre marine protected area located in Hecate Strait and Queen Charlotte Sound off the North Coast of British Columbia, Canada. The marine protected area was established in February 2017 with the goal of conserving the biological diversity, structural habitat, and ecosystem function of four glass sponge reefs. These reefs were the first discovered living specimens and are the largest glass sponge reefs in the world.
Amphiporida is an extinct order of stromatoporoid sponges which lived from the mid-late Silurian to the Late Devonian. Most amphiporids can be easily distinguished by their dendroid (bush-shaped) form, resembling a thicket of thin branches. Each 'branch' has an external frame-like 'sheath' surrounding the internal structure. Pillars and isolated longitudinal canals are typical internal components, though the overall texture is more irregular than in other stromatoporoids. Laminae or cyst plates perpendicular to the axis of growth may also develop in some species.
