Koelga is an extinct genus of prawn in the order Decapoda. It contains the species Koelga curvirostris and Koelga muensteri. [1] [2]
The Solnhofen Plattenkalk, or Solnhofen Limestone, geologically known as the Altmühltal Formation, is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies. The most familiar fossils of the Solnhofen Plattenkalk include the early feathered theropod dinosaur Archaeopteryx preserved in such detail that they are among the most famous and most beautiful fossils in the world. The Solnhofen beds lie in the German state of Bavaria (Bayern), halfway between Nuremberg (Nürnberg) and Munich (München) and were originally quarried as a source of lithographic limestone. The Jura Museum situated in Eichstätt, Germany has an extensive exhibit of Jurassic fossils from the quarries of Solnhofen and surroundings, including marine reptiles, pterosaurs, and one specimen of the early bird Archaeopteryx.
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.

Trachyteuthis is a genus of fossil cephalopod, comprising five species: T. hastiformis, T. latipinnis, T. nusplingensis, T. teudopsiformis, T. covacevichi and T. chilensis.
Lithographic limestone is hard limestone that is sufficiently fine-grained, homogeneous and defect free to be used for lithography.
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.
Albertoppelia is an extinct genus of prawn which existed during the Late Jurassic period, named after Albert Oppel. It contains the single species Abertoppelia kuempeli. Fossils of Albertoppelia were recovered from the Eichstätt Formation in Bavaria, Germany.
Carpopenaeus is an extinct genus of prawn, which existed during the Upper Jurassic and Cretaceous periods. It contains three species.
Cretasergestes sahelalmaensis is an extinct species of prawn which existed in Lebanon during the Late Cretaceous period, the only species in the genus Cretasergestes.
Pseudodusa is an extinct genus of prawn, containing only the species Pseudodusa frattigianii, known from the Solnhofen limestones of southern Germany.
Buergerocaris is an extinct genus of shrimp, containing only one species, Buergerocaris psittacoides.
Hefriga is an extinct genus of shrimp in the order Decapoda. It contains three species, and lived in the Jurassic period.
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.
Coleia is an extinct genus of decapods in the group Polychelida that lived from the Late Triassic to the Late Jurassic. It was described by Broderip in 1835, and the type species is C. antiqua. A new species, C. martinlutheri, which existed during the Sinemurian of what is now Germany, was described by Günter Schweigert and Werner Ernst in 2012.
Cycleryon is an extinct genus of decapod crustaceans. The type species is Cycleryon propinquus.
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.
The Calcare di Sogno is a geological formation in Italy, dated to roughly between 183-181 million years ago and covering the Toarcian stages of the Jurassic Period in the Mesozoic Era. Thallatosuchian remains are known from the formation.
2020 in arthropod palentology 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.
Cephalodiscus nusplingensis is an extinct hemichordate species from the Upper Jurassic of southwestern Germany.
