Acanthochirana is an extinct genus of prawn that existed during the upper Jurassic period. [3] It was named by E. Strand in 1928, and its type species is Acanthochirana cordata. [2] [4] They are distinguished from the related genus Aeger by the presence of teeth on the rostrum, which are absent in Aeger. [5]
As of 2014 [update] , Acanthochirana includes six to seven species: [6] [lower-alpha 1]
Homarus is a genus of lobsters, which include the common and commercially significant species Homarus americanus and Homarus gammarus. The Cape lobster, which was formerly in this genus as H. capensis, was moved in 1995 to the new genus Homarinus.
Penaeidae is a family of marine crustaceans in the suborder Dendrobranchiata, which are often referred to as penaeid shrimp or penaeid prawns. The Penaeidae contain many species of economic importance, such as the tiger prawn, whiteleg shrimp, Atlantic white shrimp, and Indian prawn. Many prawns are the subject of commercial fishery, and farming, both in marine settings, and in freshwater farms. Lateral line–like sense organs on the antennae have been reported in some species of Penaeidae. At 210 metres per second (760 km/h), the myelinated giant interneurons of pelagic penaeid shrimp have the world record for impulse conduction speed in any animal.
Sergestidae is a family of prawns which have lived since at least the Middle Jurassic (Bajocian/Bathonian). It contains the following genera:
The Forni Dolostone, also known as the Dolomia di Forni, is a Late Triassic dolomite geological formation in northeastern Italy. The formation was deposited in a lagoonal to shallow marine environment.
Eubrachyura is a group of decapod crustaceans comprising the more derived crabs. It is divided into two subsections, based on the position of the genital openings in the two sexes. In the Heterotremata, the openings are on the legs in the males, but on the sternum in females, while in the Thoracotremata, the openings are on the sternum in both sexes. This contrasts with the situation in other decapods, in which the genital openings are always on the legs. Heterotremata is the larger of the two groups, containing the species-rich superfamilies Xanthoidea and Pilumnoidea and all the freshwater crabs. The eubrachyura is well known for actively and constantly building its own burrows. The fossil record of the Eubrachyura extends back to the Cretaceous; the supposed Bathonian representative of the group, Hebertides jurassica, ultimately turned out to be Cenozoic in age.
Corystidae is a family of crabs, in its own superfamily, Corystoidea. It includes what was once thought to be the oldest Eubrachyuran fossil, Hebertides jurassica, thought to be dating from the Bathonian ; the species was subsequently reinterpreted as being Cenozoic in age. Corystidae contains ten extant and five extinct species in eight genera:
Carpopenaeus is an extinct genus of prawn, which existed during the Upper Jurassic and Cretaceous periods. It contains three species.
Hakelocaris vavassorii is an extinct species of prawn belonging to the family Penaeidae. It was named in 1994 by Alessandro Garassino, and is the only species in the genus Hakelocaris.
Koelga is an extinct genus of prawn in the order Decapoda. It contains the species Koelga curvirostris and Koelga muensteri.
Satyrocaris is an extinct genus of prawn in the family Penaeidae that existed during the Triassic in what is now Italy. It was described by Garassino and Teruzzi in 1993, and the type species is Satyrocaris cristatus.
Hefriga is an extinct genus of shrimp in the order Decapoda. It contains three species, and lived in the Jurassic period.
The Galatheoidea are a superfamily of decapod crustaceans comprising the porcelain crabs and some squat lobsters. Squat lobsters within the three families of the superfamily Chirostyloidea are not closely related to the squat lobsters within the Galatheoidea. The fossil record of the superfamily extends back to the Middle Jurassic genus Palaeomunidopsis.
Cancrinos is a genus of fossil crustacean closely allied with the slipper lobsters. One species is known, C. claviger from the Jurassic of southern Germany.
This list of fossil arthropods described in 2014 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods of every kind that have been described during the year 2014. The list only includes taxa at the level of genus or species.
Cycleryon is an extinct genus of decapod crustaceans. The type species is Cycleryon propinquus.
This list of fossil arthropods described in 2017 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods of every kind that are scheduled to be described during the year 2017, as well as other significant discoveries and events related to arthropod paleontology that are scheduled to occur in the year 2017.
Paracancrinos is a prehistoric genus of crustacean that lived during the Upper Cretaceous in what is now Lebanon. It contains a single species, P. libanensis, which was originally described as a species of Cancrinos in 2006, but was moved to its own genus in 2016.
Palinurina is an extinct genus of crustaceans, belonging to the decapods. These animals lived between the Lower Jurassic and the Upper Jurassic and their fossils can be found in Europe. This crustacean is considered one of the oldest lobsters.
2020 in arthropod paleontology is a list of new arthropod fossil taxa, including arachnids, crustaceans, insects, trilobites, and other arthropods that were announced or described, as well as other significant arthropod paleontological discoveries and events which occurred in 2020.
Notahomarus is a genus of fossil lobster belonging to the family Nephropidae that is known from fossils found only in Lebanon. The type species, N. hakelensis, was initially placed within the genus Homarus in 1878, but it was transferred to the genus Notahomarus in 2017.
