A fundamental question in biology is whether phenotypes can be predicted by ecological or
genomic rules. At least five cases of convergent evolution of the crab‐like body plan (with a …

Our knowledge of fossil crustaceans from the tropics has increased considerably during
recent decades, thanks to novel findings and the re-examination of museum specimens …

Evolutionary origins of novel forms are often obscure because early and transitional fossils
tend to be rare, poorly preserved, or lack proper phylogenetic contexts. We describe a new …

Phylogenetic analysis of most genera within fossil and extant Raninoida (Brachyura) based
on 72 adult morphological characters yielded a new superfamily and family level …

Compared with the elongate bodies of shrimps or lobsters, crabs are characterised by a
compact body organisation with a depressed, short carapace and a ventrally folded pleon …

Despite the extensive fossil record of higher crabs (E ubrachyura) from L ate C retaceous
and C enozoic rocks worldwide, their E arly C retaceous occurrences are scarce and …

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 …

Phylogenetic analysis of most species within Necrocarcinoidea based upon 55 adult
morphological characters supports the inclusion of 5 families within the superfamily. Two …

A highly diverse decapod crustacean fauna is described from the classic Aptian outcrop of
Cal Cassanyes (Castellet i la Gornal) in Catalonia. Although decapod crustaceans are a …

Despite the exceptional palaeontological richness of the renowned Santana Group from the
Early Cretaceous Araripe Basin of Brazil, only one specimen of true crabs (Brachyura) has …
