Cretasergestes sahelalmaensis is an extinct species of prawn which existed in Lebanon during the Late Cretaceous period, the only species in the genus Cretasergestes. [1]
The Glypheoidea, is a group of lobster-like decapod crustaceans which forms an important part of fossil faunas, such as the Solnhofen limestone. These fossils included taxa such as Glyphea, and Mecochirus, mostly with elongated chelipeds. This group of decapods is a good example of a living fossil, or a lazarus taxon, since until their discovery in the 1970s, the group was considered to have become extinct in the Eocene. The superfamily Glypheoidea comprises five families. The two extant species, Neoglyphea inopinata and Laurentaeglyphea neocaledonica, are both in the family Glypheidae.
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:
Scyllarides is a genus of slipper lobsters.
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.
Macropenaeus is an extinct genus of prawn in the order Decapoda, containing two species: the type species M. incertus, known from the Late Cretaceous (Cenomanian) of Lebanon, and M. sidiaichensis known from the Early Cretaceous (Barremian) of Tunisia.
Palibacus praecursor is a fossil species of slipper lobster, the only species in the genus Palibacus. It was found in Cenomanian (Cretaceous) deposits at Hakel, Lebanon and described in 1886 by the German palaeontologist W. Dames. Its similarity to modern slipper lobsters demonstrates that the main features of that group had already evolved by the mid-Cretaceous.
