ABSTRACT All Jurassic brachyuran taxa known to date are based solely upon dorsal carapaces, and only a limited number of Early and mid-Cretaceous crabs retain ventral parts. Therefore, all Jurassic taxa and many forms from the first half of the Cretaceous are carapace-based entities. All of them are considered to be “dromiaceans”, podotremes to be precise. The recent discovery of an exceptionally well-preserved male crab from the Upper Cretaceous (lower Cenomanian) of Chiapas (Mexico… 
Bajoprosopon piardi n. gen. and sp. from the Middle Jurassic of France, with a revised diagnosis of the family Prosopidae von Meyer, 1860 (Brachyura, Podotremata) and notes on the availability of names introduced by Hermann von Meyer (1835, 1857)
TLDR
A new genus and species of homolodromioid crab of Bajocian (early Middle Jurassic) age from Calvados (northwest France) is recorded, based on a unique dorsal carapace, assigned to the primitive family Prosopidae.
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 studied
The Inachoididae spider crabs (Crustacea, Brachyura) from the Neogene of the tropical Americas
Abstract. The spider crabs Willinachoides santanai n. gen. n. sp. from the early-middle Miocene of north Brazil and Paradasygyius rodriguezi n. sp. from the late Miocene of Venezuela are described
First record of a homolid crab (Crustacea: Decapoda: Homoloidea) from the early Eocene of the Iberian Peninsula
We describe a new species of homolid crab from the Ypresian (early Eocene) Roda Formation of Huesca province (Aragon, Spain). In spite of the fragmentary condition of the sole specimen, some
A highly diverse dromioid crab assemblage (Decapoda, Brachyura) associated with pinnacle reefs in the lower Eocene of Spain
Abstract A highly diverse fauna of dromioid brachyurans from the Serraduy Formation (lower Eocene) in the western Pyrenees (Huesca, Spain) is described and illustrated. Recorded taxa are Mclaynotopus
Locomotion and feeding trails produced by crabs
Trace fossils represent the biological activity of an organism in the form of trails, tracks, burrows, and borings in the geological record. Bilobate trails are known to be made by arthropod

Abstract A rich collection of Brachyura from the famous Cenomanian “Fish Beds” of western Lebanon has permitted the reevaluation of several families of decapod crustaceans during an important period
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)
TLDR
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.
The oldest higher true crabs (Crustacea: Decapoda: Brachyura): insights from the Early Cretaceous of the Americas
TLDR
The ages and geographical distributions of the oldest eubrachyuran‐like taxa suggest that the oldest higher true crabs might have originated in the Americas; that they were already morphologically diverse by the late Early Cretaceous; and that their most recent common ancestor must be rooted in the EarlyCretaceous, or even the Late Jurassic.
A new Classification for some Jurassic Brachyura (Crustacea: Decapoda: Brachyura: Homolodromioidea): families GoniodromitidaeBeurlen, 1932 and Tanidromitidae new family
TLDR
A new family, Tanidromitidae, and two new genera are erected to embrace several Jurassic species of brachyurans from northern Europe, based upon their possession of a unique combination of orbital and dorsal carapace characters.
A revision of the Palaeocorystoidea and the phylogeny of raninoidian crabs (Crustacea, Decapoda, Brachyura, Podotremata)
TLDR
Comparative morphology of the thoracic sternum, abdominal holding structures, the sternum-pterygostome configuration, respiratory physiology and spermathecae, all reveal polarities of the raninoidian clade.

TLDR
Comparisons with other raninoidans support the hypothesis that a more ‘crab-like’ body plan is the plesiomorphic condition for raninoidsans, and that the ‘frog- like’ architecture of Palaeocorystidae, and perhaps the Raninoidea as a whole, reflects a derived condition related to a specialized burrowing lifestyle.
