The definition of the brachyuran genus Glyphithyreus Reuss, 1859 (= Plagiolophus Bell, 1858non Pomel, 1857) is herein restricted such that now embraces four species ranging from Paleocene to Oligocene in age. Other previously referred have been placed other genera, resulting one new genus, Chirinocarcinus, and combinations, Chirinocarcinus wichmanni ( Feldmannet al., 1995), Lobonotus sturgeoni Stintonius markgrafi Lőrenthey, 1907 [1909]), Titanocarcinus bituberculatus Collins Jakobsen,...
Finely preserved fossil assemblages (lagerstätten) provide crucial insights into evolutionary innovations in deep time. We report an exceptionally Early Triassic assemblage, the Guiyang Biota, from Daye Formation near Guiyang, South China. High-precision uranium-lead dating shows that age of Biota is 250.83 +0.07/–0.06 million years ago. This only 1.08 ± 0.08 after severe Permian-Triassic mass extinction, and this assemblage therefore represents oldest known Mesozoic lagerstätte found so...
Lobsters are a ubiquitous and economically important group of decapod crustaceans that include the infraorders Polychelida, Glypheidea, Astacidea Achelata. They familiar forms such as spiny, slipper, clawed lobsters crayfish unfamiliar deep-sea "living fossil" species. The high degree morphological diversity among these has led to dynamic classification conflicting hypotheses evolutionary relationships. In this study, we estimated phylogenetic relationships major groups all lobster families...
The infraorder Anomura has long captivated the attention of evolutionary biologists due to its impressive morphological diversity and ecological adaptations. To date, 2500 extant species have been described but phylogenetic relationships at high taxonomic levels remain unresolved. Here, we reconstruct history—phylogeny, divergence times, character evolution diversification—of this speciose clade. For purpose, sequenced two mitochondrial (16S 12S) three nuclear (H3, 18S 28S) markers for 19 20...
Abstract Aim The sequential break‐up of Gondwana is thought to be a dominant process in the establishment shared biota across landmasses Southern Hemisphere. Yet similar distributions are by taxa whose radiations clearly post‐date Gondwanan break‐up. Thus, determining contribution vicariance versus dispersal seemingly complex. southern freshwater crayfishes (family Parastacidae) distributed on Australia and New Guinea, South America, Madagascar Zealand unlikely have dispersed via oceans,...
A phylogenetic analysis including representatives from 44 extinct and 27 extant families of lobsters (Polychelida, Achelata, Glypheidea, Astacidea), resulted in the recognition one new superfamily, Glaessnericarioidea, three families, Glaessnericariidae, Neoglypheidae, Litogastroidae. Two Protastacidae Stenochiridae, are elevated to superfamily status. classification Glypheidea is proposed currently known genera rearranged based upon analysis. Palaeopalaemonida given a separate infraordinal...
The superfamily Portunoidea including extinct lineages is herein evaluated via cladistic analysis of adult morphological characters and traditional systematics. Nearly every fossil species has been examined type material, or if this was not possible, through illustrations original descriptions. analyses indicate that the much more diverse at family level than previously recognized, three subfamilies, Catoptrinae, Carcininae, Macropipinae, are elevated to status. One new family,...
A phylogenetic analysis based upon 30 extinct and extant taxa of podotrematous brachyuran decapods using 74 characters shows that Podotremata sensu Guinot, 1977 is not monophyletic results in a new classification for these crabs. Four are recognized at the section-level (Homoloida, Torynommoida, Etyoida, Dakoticancroida) as well two families (Basinotopidae Xandarocarcinidae). Dromiacea historically defined redefined herein to exclude Homoloidea. New generic names Noetlingocarcinus...
Ecosystems changed dramatically during the Mesozoic marine revolution, including rise of decapod crustaceans such as lobsters, shrimp, true crabs, and squat lobsters. However, quantitative patterns biodiversity through geological time are virtually unknown. This hampers our understanding their importance in past ecosystems timing causes radiations extinctions. Based on compilation ~1300 species, we document a long-term shift diversity dominant groups, marked by fi rst appearance increasing...
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, exceptionally preserved enigmatic crab from the mid-Cretaceous Colombia United States, whose completeness illuminates disparity group forms. Its large unprotected compound eyes, small fusiform body, leg-like mouthparts suggest larval trait retention into adulthood via heterochronic development (pedomorphosis),...
Our knowledge of fossil crustaceans from the tropics has increased considerably during recent decades, thanks to novel findings and re-examination museum specimens. However, several previous records have been misidentified, numerous specimens never reported, many new discoveries are yet be published. Here, we present a detailed, up-to-date, revised checklist for every marine, terrestrial, or freshwater decapod crustacean occurrence tropical America known us, including their age, geographic...
A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato , resulting in one new family, Hypothalassiidae. Four xanthoid are elevated to superfamily status, Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, Goneplacoidea, numerous subfamilies family status. The Mathildellidae is moved Goneplacidae Portunoidea. Diagnoses for superfamilies discussed herein provided, embracing characters typically used...
Paleobiogeographic patterns of decapod crustaceans from the Southern Hemisphere, based upon 441 species-level records arrayed in 154 genera, document global distribution that can be compared to those previously published on decapods North Pacific and Central American regions. All known Hemisphere spanning Early Triassic Pleistocene have been compiled, nearly all personally verified, origin interpreted. Interchange between hemispheres, including amphitropical bipolar distributions, are...
Phylogenetic analysis of most genera within fossil and extant Raninoida (Brachyura) based on 72 adult morphological characters yielded a new superfamily family level classification for the section. The section was diverse at during Late Cretaceous but remains genus species in Holocene. New subfamilies include Bicornisranininae, Macroacaeninae, Rogueinae Lyreididae. Colombicarcinus, Alessandranina, Claudioranina, Giulianolyreidus Italianira, one species, Colombicarcinus laevis, is described....
Patterns of diversity and faunal turnover major groups decapod crustaceans throughout the Phanerozoic are analyzed based upon data from all known fossil species reported to date. Age, range, habitat preference were compiled for 3637 arrayed in 1035 genera 173 families. Grouped at infraordinal level, Anomura, Gebiidea, Axiidea consistently occupied specific, preferred environments their geologic history. Achelata a variety siliciclastic until Holocene when they found coral other carbonate...
