Acanthochirana
''Acanthochirana'' is an extinct genus of prawn that existed during the upper Jurassic period. It was named by E. Strand in 1928, and its type species is ''Acanthochirana cordata''. They are distinguished from the related genus '' Aeger'' by the presence of teeth on the rostrum, which are absent in ''Aeger''. Species , ''Acanthochirana'' includes six to seven species: * ''Acanthochirana angulata'' *''Acanthochirana cenomanica'' * ''Acanthochirana cordata'' *''Acanthochirana krausei'' *''Acanthochirana liburiansis'' *''Acanthochirana smithwoodwardi'' *''Acanthochirana triassica'' Notes References External links ''Acanthochirana''at the Paleobiology Database The Paleobiology Database is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms.

Dendrobranchiata
Dendrobranchiata is a suborder of Decapoda, decapods, commonly known as prawns. There are 540 extant species in seven families, and a fossil record extending back to the Devonian. They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills and by the fact that they do not brood their eggs, but release them directly into the water. They may reach a length of over and a mass of , and are widely shrimp fishery, fished and shrimp farm, farmed for human consumption. Shrimp and prawns While Dendrobranchiata and Caridea belong to different Order (biology), suborders of Decapoda, they are very similar in appearance, and in many contexts such as commercial farming and Fishery, fisheries, they are both often referred to as "shrimp" and "prawn" interchangeably. In the United Kingdom, the word "prawn" is more common on menus than "shrimp", while the opposite is the case in North America. The term "prawn" is also loosely used to describe any large s ...

Archiv Für Naturgeschichte
''Archiv für Naturgeschichte'' was a German-language journal for natural history. It was founded by A. F. A. Wiegmann in 1835. The journal was published in Berlin from 1835 to 1926. There were 92 published volumes. From 1912 to 1926 each volume was published in two sections, namely, ''Abteilung A: Original-Arbeiten'' & ''Abteilung B: Jahres-Berichte''. ''Abteilung A'' (''i.e.'' Section A) published original articles on zoology. ''Abteilung B'' (''i.e.'' Section B) published yearly reports on zoological articles published in the preceding year.

Jurassic Crustaceans
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassic, ...
