Corazzatocarcinus is an extinct genus of Cretaceous crabs. [1] [2] This genus include the species Corazzatocarcinus hadjoulae Roger 1946. [3]
Corazzatocarcinus is known in Cretaceous of Lebanon (from about 99.7 to 94.3 million years ago). [3]
Cancridae is a family of crabs. It comprises six extant genera, and ten exclusively fossil genera, in two subfamilies:
Retroplumidae is a family of heterotrematan crabs, placed in their own (monotypic) superfamily, Retroplumoidea.
The thumbnail crab, Thia scutellata, is a species of decapods, in the family of thiidae, whose carapace resembles a human thumbnail, a dense fringe of long hairs distinctly notched around the edge. Pale pink in colour with red to brown markings. It is found in the North Sea, north-east Atlantic and Mediterranean Sea. It is the only extant species in the genus Thia, although two fossil species are known. Their predators includes the atlantic cod.
Hippoidea is a superfamily of decapod crustaceans known as mole crabs or sand crabs.
Goneplacidae is a family of crabs of the order Decapoda and the superfamily Goneplacoidea. It includes the following genera:
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.
Tanaocheles is a genus of crabs, the only genus in the family Tanaocheleidae. It contains two species, T. bidentata and T. stenochilus. The two species were formerly placed in different families, and they were only shown to be related, and placed in a new subfamily, in 2000.
Paleomattea is an extinct genus of prawn, containing the single species Paleomattea deliciosa. The species is only known from the stomach contents of the fish Rhacolepis, which is referred to by the specific epithet deliciosa ("delicious"), and in the generic name, where mattea means "delicacy".
Planes is a genus of crabs in the family Grapsidae that currently comprises three extant species: Planes minutus, Planes marinus Rathbun, 1914, and Planes major (=cyaneus). A further fossil species is known from the Middle Miocene of the Caucasus.
Metopograpsus is a genus of crabs, containing the following extant species:
Epialtidae is a family of crabs, containing the subfamilies:
Xantho is a genus of crabs in the family Xanthidae, containing five extant species, all restricted to the north-east Atlantic Ocean and Mediterranean Sea, although Xantho granulicarpis is not universally recognised as a separate species from Xantho hydrophilus:
Paraetisus globulus is a species of crab in the family Xanthidae, the only species in the genus Paraetisus. It was described in 1933 by Charles Melbourne Ward.
Polydectus cupulifer is a species of crab in the family Xanthidae, and the only species in the genus Polydectus. Together with the genus Lybia, it forms the subfamily Polydectinae. It is found in the Indo-Pacific, ranging from Madagascar and the Red Sea in the west to Japan, Hawaii and French Polynesia in the east. P. cupulifer is densely covered with setae (bristles), and frequently carries a sea anemone in each chela (claw).
Xanthodius is a genus of crabs in the family Xanthidae, containing one exclusively fossil species and the following extant species:
Zosimus is a genus of crabs in the family Xanthidae, containing the following species:
Galenidae is a family of crabs, one of three in the superfamily Pilumnoidea. It contains four genera, three of which are monotypic. At present five species have been described in this family.
Ethusidae is one of two extant families of crabs in the superfamily Dorippoidea. It contains four genera. Members of this family are found in marine environments at depths from 16m to 4,192m.
Galene is a genus of crabs belonging to the family Galenidae.
Necrocarcinidae is an extinct family of Late Jurassic and Cretaceous crabs. It comprises 40 species grouped in seven genera.
