Spider crabs (Majoidea) are well-known from modern oceans and are also common in the western part of the Atlantic Ocean. When spider crabs appeared in the Western Atlantic in deep time, and when they became diverse, hinges on their fossil record. By reviewing their fossil record, we show that (1) spider crabs first appeared in the Western Atlantic in the Late Cretaceous, (2) they became common since the Miocene, and (3) most species and genera are found in the Caribbean region from the Miocene… Expand
Paleobiogeography of the fossil box crab Calappilia (Brachyura: Calappidae) with a new species from the Eocene-Oligocene of Florida, USA
It is hypothesized that individuals of Calappilia crossed the Central American Seaway prior to the closure of the Isthmus of Panama and they also migrated across the Tethys Sea, suggesting dispersal well into the Southern Hemisphere by the Miocene. Expand
Checklist of fossil decapod crustaceans from tropical America. Part I: Anomura and Brachyura
A detailed, up-to-date, and revised checklist for every marine, terrestrial, or freshwater fossil decapod crustacean occurrence from tropical America known to us, including their age, geographic occurrences, and related literature is presented. Expand
Taphonomy and ontogeny of the brachyuran crab Exucarcinus gonzagai, from the lower cretaceous (Aptian) Romualdo Formation, Araripe Basin, NE brazil
Abstract Brachyurans played important ecological and evolutionary roles in the marine benthic communities of the past and were the components of the Mesozoic Decapod Revolution. Therefore, the searchExpand
Early Cretaceous (late Barremian) Crustacea from Puebla, Mexico
Abstract The oldest record of fossil decapods, associated to reefs from Mexico is reported. Six species of Anomala and brachyuran crustaceans, collected from limestones of the upper BarremianExpand
Larval development of the Caribbean king crab Maguimithrax spinosissimus (Lamarck, 1818), the largest brachyuran in the western Atlantic (Crustacea: Decapoda: Majoidea)
Abstract The complete larval development of the spider crab Maguimithrax spinosissimus (Lamarck, 1818) is re-described and illustrated in detail from laboratory-reared material. The developmentExpand
Archaeochiapasidae n. fam., a new early Cenomanian brachyuran family from Chiapas, Mexico, new hypothesis on Lecythocaridae Schweitzer & Feldmann, 2009, and phylogenetic implications (Crustacea, Decapoda, Brachyura, Eubrachyura)
One of the earliest eubrachyurans with unique features is identified, namely a very wide thoracic sternum displaying an unexpected structure for a lower Cenomanian representative, and a depressed, rimmed area (‘flange’) along the carapacePostero- and postero-lateral margin. Expand
Systematics and convergent evolution of multiple reef-associated Jurassic and Cretaceous crabs (Decapoda, Brachyura)
The Late Jurassic marks the first major radiation among true crabs (Brachyura) in reef environments, followed by another diversification in the midto Late Cretaceous in multiple habitats. We studiedExpand
Phylogeographic patterns in Maguimithrax spinosissimus (Decapoda: Mithracidae) from Colombian Caribbean
The authors' analysis showed two genetic stocks and possibly an isolated biogeographic unit of M. spinosissimus in one oceanic and two continental islands, which is an important artisanal fisheries resource with a distribution range that includes the Florida Keys and Caribbean Sea islands. Expand
Majoidea crabs from Guadeloupe Island, with a documented list of species for the Lesser Antilles (Crustacea, Decapoda, Brachyura, Majoidea)
ABSTRACT A collection of Majoidea Samouelle, 1819 crabs carried out during the KARUBENTHOS 2012 Expedition to Guadeloupe Island and sorted during an international workshop at Besse-et-Saint-AnastaiseExpand
Larval stages of the crab Mithrax tortugae (Brachyura: Mithracidae) with comparisons between all species of Mithrax
The analyses of larval morphology and the results of the molecular analyses reinforced recognition of the relationships among M. tortugae, M. hispidus and M. pleuracanthus. Expand


Fossil crabs (Crustacea: Decapoda) from the Late Cretaceous cárdenas Formation, east-central Mexico
Twenty-four nearly complete carapace samples were collected at three different localities of the Maastrichtian (Late Cretaceous) Cardenas Formation in San Luis Potosi, east-central Mexico. TheExpand
Antarctomithrax thomsoni, a new genus and species of crab (Brachyura; Majidae) from the La Meseta Formation (Eocene) of Seymour Island, Antarctica
A new genus and species of spider crab (family Majidae) is reported from the lower part of the La Meseta Formation, which represents the second fossil majid to be described from Antarctica. Expand
Crustáceos (Decapoda: Brachyura) fósiles de Cuba.
Three families, two genera and two species are recorded for the first time for the Cuban Cretaceous to Pleistocene geologic age. The genera Persephona Leach, 1817 (Leucosiidae), Mithrax Desmarest,Expand
A new coral-associated decapod assemblage from the Upper Miocene (Messinian) Upper Coralline Limestone of Malta (Central Mediterranean)
Abstract:  A rich coral-associated decapod assemblage is recorded from the ‘Depiru Beds’ of the upper part of the Upper Coralline Limestone (Messinian, Upper Miocene), from the island of Malta.Expand
Etyid crabs (Crustacea, Decapoda) from mid‐Cretaceous Reefal strata of Navarra, northern Spain
The genus Xanthosia may have evolved in an environment dominated by deposi- tion of siliciclastics, rather than chalks, and as the distribution of all known specimens demonstrates, E. fossa inhabited various environments. Expand
The Oldest Frog Crabs (Decapoda: Brachyura: Raninoida) from the Aptian of Northern South America
The discovery of Notopocorystes kerri is the oldest fusiform raninoid known to date, revealing that the morphological innovation of a fUSiform carapace was already evolved in Raninoida before the rapid radiation experienced during Albian times. Expand
The Cretaceous crab Rathbunopon : revision, a new species and new localities
The crab genus Rathhunopon is exclusively known from Cretaceous rocks, mainly from Europe. Here two new European localities are presented: one in the Albian/Cenomanian of northern Spain yieldingExpand
A new species of Diaulax Bell, 1863 (Brachyura: Dialucidae) in the Early Cretaceous of the Rosablanca Formation, Colombia
