The Isalo III Formation is a geological formation in Madagascar, off the eastern coast of Africa. It dates back to the Middle Jurassic. The use of the term "Isalo III" is somewhat controversial as the two prior units Isalo I and II are Triassic cross-bedded sandstone units that form a continuous depositional sequence, while the "Isalo III" sandstones are not part of the same depositional sequence, and were deposited considerably later. and are perhaps better treated as part of several separate formations. It is traditionally divided into two subunits the lower, Bajocian aged Isalo IIIa unit also known as the Beronono Formation and the upper, Bathonian aged Isalo IIIb unit also known as the Sakaraha Formation or Sakahara Formation. The Sakaraha Formation consists of sandstones, marls and carbonates and represents a coastal plain environment, and is laterally equivalent to the predominantly carbonate Bemaraha Formation, which represents a coastal barrier lagoon complex. The formation is found in the northwest and in the southeast of the country and has provided a variety of fossils.
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.
Hexapodidae is a family of crabs, the only family in the superfamily Hexapodoidea. It has traditionally been treated as a subfamily of the family Goneplacidae, and was originally described as a subfamily of Pinnotheridae. Its members can be distinguished from all other true crabs by the reduction of the thorax, such that only seven sternites are exposed, and only four pairs of pereiopods are present. Not counting the enlarged pair of claws, this leaves only six walking legs, from which the type genus Hexapus, and therefore the whole family, takes its name. Some anomuran "crabs", such as porcelain crabs and king crabs also have only four visible pairs of legs. With the exception of Stevea williamsi, from Mexico, all the extant members are found either in the Indo-Pacific oceans, or around the coast of Africa.
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 (Gecarcinucoidea, Potamoidea. 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.
Scyllarides is a genus of slipper lobsters.
Ambilobeia is an extinct genus of prawn which existed in Ambilobé, Madagascar during the Triassic period. It contains the species Ambilobeia karojoi.
Cretapenaeus berberus is an extinct species of prawn which existed in Morocco during the Late Cretaceous period. It is the only species in the genus Cretapenaeus.
Cretasergestes sahelalmaensis is an extinct species of prawn which existed in Lebanon during the Late Cretaceous period, the only species in the genus Cretasergestes.
Longitergite is an extinct genus of prawn which existed in Russia during the Lower Miocene period. It contains a single species.
Pseudobombur is an extinct genus of crustacean, in the order Decapoda. It contains the species Pseudobombur nummuliticus .
Sagaria is an extinct genus of plants which existed in southern Italy during the Albian age. The type species is Sagaria cilentana.
Speocarcinus is a genus of crabs in the family Xanthidae, containing six extant species, one fossil species from the Late Miocene, one fossil species from the Eocene (Lutetian) and one fossil species from the Early Eocene (Ypresian):
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.
Eophasma is a genus of fossil nematodes from the Jurassic of Osteno in Lombardy, Italy. It has only one species, Eophasma jurasicum.
Bruno Parisi was an Italian zoologist and museum director. His main research field were the crustaceans (Crustacea). From 1928 to 1951 he was director of the Museo Civico di Storia Naturale di Milano.
Ostenocaris is a Jurassic species of giant Thylacocephalan crustacean, sufficiently distinct from its relatives to be placed in its own family, Ostenocarididae. It is believed to be a bethonic animal and one of the most important necrophagus animals of its environment.
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.
The Moltrasio Formation also known as Lombardische Kieselkalk Formation is a geological formation in Italy. This Formation mostly developed on the Lower or Middle Sinemurian stage of the Lower Jurassic, where on the Lombardian basin tectonic activity modified the current marine and terrestrial habitats. Here it was developed a series of marine-related depositional settings, represented by an outcrop of 550–600 m of grey Calcarenites and Calcilutites with chert lenses and marly interbeds, that recovers the Sedrina, Moltrasio and Domaro Formations. This was mostly due to the post-Triassic crisis, that was linked locally to tectonics. The Moltrasio Formation is considered a continuation of the Sedrina Limestone and the Hettangian Albenza Formation, and was probably a shallow water succession, developed on the pasive margin of the westernmost Southern Alps. It is known due to the exquisite preservation observed on the Outcrop on Osteno, where several kinds of marine biota have been recovered.
