Ciliopagurus obesus is a fossil species of hermit crab, [1] described from Rupelian (Oligocene) sediments at Sint-Niklaas, Belgium. [2]
Cylindroleberididae is a family of ostracods that shows remarkable morphological diversity. The defining feature is the possession of gills: 7–8 leaf-like pairs at the posterior of the body. Other features common to all species in the family include a "baleen-comb" on both the maxilla and the fifth limb, a sword-shaped coxal endite on the mandible, and the triaenid bristles on the basal endites of the mandible.
Betasuchus is a genus of theropod dinosaur which lived during the Late Cretaceous Period. Betasuchus is, besides Orthomerus, the only dinosaur genus named from remains found in the Netherlands and the only non-avian theropod found in the Maastrichtian Beds.
Orthomerus is a genus of dubious hadrosaurid dinosaur from the Late Cretaceous of The Netherlands and possibly also Spain. It is today an obscure genus, but in the past was conflated with the much better known Telmatosaurus.
The Diogenidae are a family of hermit crabs, sometimes known as "left-handed hermit crabs" because in contrast to most other hermit crabs, its left chela (claw) is enlarged instead of the right. It comprises 429 extant species, and a further 46 extinct species, making it the second-largest family of marine hermit crabs, after the Paguridae.
Dromiidae is a family of crabs, often referred to as sponge crabs. They are small or medium-sized crabs which get their name from the ability to shape a living sponge into a portable shelter for themselves. A sponge crab cuts out a fragment from a sponge and trims it to its own shape using its claws. The last two pairs of legs are shorter than other legs and bend upward over the crab's carapace, to hold the sponge in place. The sponge grows along with the crab, providing a consistent shelter.
Etyiidae is a prehistoric family of dromiacean crabs only known from Cretaceous and a few Paleocene fossils. Seven genera are included:
Albuneidae is a little-known family of specialized burrowing sand crabs. There are 50 extant species as well as nine fossil species that have been described. Fossil specimens have been described from the Cretaceous, Miocene and Oligocene.
Albunea is a genus of mole crab within the Albuneidae. Little is known about this group's biology. A. groeningi is named after Matt Groening, creator of The Simpsons.
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:
Ciliopagurus is a genus of hermit crabs, of the family Diogenidae, which are sometimes referred to as the "left-handed hermit crabs", because in contrast to most other hermit crabs, the left chela (claw) is enlarged instead of the right. They are found in the Indo-Pacific region and in the eastern Atlantic Ocean.
Ciliopagurus tricolor is a species of hermit crab native to Madagascar. It is one of four species in the "strigatus complex", having morphological similarities to C. strigatus, with the most prominent variance being coloration.
Ciliopagurus caparti is a species of hermit crab native to South East Atlantic.
Ciliopagurus krempfi is a species of hermit crab from the Indo-Pacific.
Ciliopagurus tenebrarum is a species of hermit crab native to Cape Comorin.
Ciliopagurus vakovako is a species of hermit crab native to the Marquesas Islands. It is typically found at a depth no lower than 57 metres (187 ft). C. vakovako appears to be a vicariant of C. strigatus, a species widespread throughout the Indo-pacific region.
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.
Cyclida is an extinct order of crab-like fossil arthropods that lived from the Carboniferous to the Cretaceous. Their classification is uncertain, but they are generally interpreted as crustaceans, likely belonging to Multicrustacea.
Mesoparapylocheles is an extinct hermit crab genus which existed during the Mesozoic in what is now Europe. It was described by René H.B. Fraaije, Adiël A. Klompmaker and Pedro Artal in 2012. The type species is Mesoparapylocheles michaeljacksoni from the Albian or Cenomanian of Spain; it was named after the singer Michael Jackson. Genus also includes two species from the Late Jurassic (Kimmeridgian) of Germany and additional two species from the Late Jurassic (Tithonian) of Austria.
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.
Pirimelidae is a family of crustaceans belonging to the order Decapoda.
