Abstract Vision has revolutionized the way animals explore their environment and interact with each other rapidly became a major driving force in animal evolution. However, direct evidence of how ancient could perceive is extremely difficult to obtain because internal eye structures are almost never fossilized. Here, we reconstruct unprecedented resolution three-dimensional structure huge compound 160-million-year-old thylacocephalan arthropod from La Voulte exceptional fossil biota SE...
Ecological significance of the arthropod fauna from Jurassic
We report and illustrate several unpublished fossil specimens of marine arthropods, housed at the Muséum national d'Histoire naturelle in Paris (France) coming from Solnhofen Nusplingen Lithographic Limestones (Late Jurassic, Germany). Notably, we describe Antrimpos undenariusSchweigert, 2001, Eryma modestiforme (Schlotheim, 1822) Mecochirus longimanatus 1820). forestiSecrétan, 1968 is considered as a junior synonym longimanatus. A revision previously described also realized. This...
Polychelidan lobsters (Decapoda: Polychelida) are crustaceans with extant species which restricted to deep water environments. Fossil species, however, used live in more varied palaeoenvironments, from shallow water, and were diverse morphologically. We redescribe two of polychelidan lobsters, the Late Triassic Rosenfeldia triasica Garassino, Teruzzi & Dalla Vecchia, 1996 Jurassic Eryon oppeli Woodward, 1866, recently assigned same genus, Rosenfeldia, based upon only a few characters....
The marine clawed lobster genus PseudastacusOppel, 1861, previously known mainly from the Late Jurassic lithographic limestones of Bavaria (Germany), is herein recorded Early (Sinemurian, c. 190-199 Ma) France. A new species, Pseudastacus lemovices n. sp., introduced. It oldest representative and family Stenochiridae Beurlen, 1828.
Erymoid lobsters (Crustacea, Decapoda, Erymoidea) are an important component of Mesozoic crustacean faunas in Europe, especially during the Jurassic. With 36 species reported, these reach their highest diversity Late After review presented here, 23 belonging to ErymaMeyer, 1840 (11 species), PalaeastacusBell, 1850 (2 PustulinaQuenstedt, 1857 species) and StenodactylinaBeurlen, 1928 (8 remain valid. One new is described: Stenodactylina shotoverigiganti n. sp., Eryma pseudoventrosaBeurlen,...
Abstract Ichthyosauria, Plesiosauria, and Metriorhynchidae were apex predators in Mesozoic oceanic trophic networks. Previous stable oxygen isotope studies suggested that several taxa belonging to these groups endothermic some of them homeothermic organisms. However, conclusions remain contentious owing the associated uncertainties regarding δ 18 O value fractionation relative environmental seawater. Here, we present new bioapatite phosphate values (δ p ) (Middle Jurassic Early Cretaceous)...
A phylogenetic analysis of a total 31 species: 27 fossil species from seven families (Glypheidae, Litogastridae, Mecochiridae, Pemphicidae, Erymidae, Clytiopsidae, Chimaerastacidae), and four extant three Nephropidae, Stenopodidae) is proposed. Most the genera considered are coded exclusively based upon their type and, as much possible, specimens. The cladistic demonstrates that glypheidean lobsters (infraorder Glypheidea) form monophyletic group including two superfamilies: Glypheoidea...
Two new polyneopteran insect nymphs from the Montceau-les-Mines Lagerstätte of France are presented. Both preserved in three dimensions, and imaged with aid X-ray micro-tomography, allowing their morphology to be recovered unprecedented detail. One–Anebos phrixos gen. et sp. nov.–is uncertain affinities, preserves portions antennae eyes, coupled a heavily spined habitus. The other is roachoid long chewing mouthparts very similar form most generalized mandibulate extant orthopteroid insects....
A new Jurassic fossiliferous Plattenkalk has been discovered at Monte Fallano (Caserta, Campania, southern Italy). Biostratigraphic analyses indicate a Bajocian/Bathonian age (Middle Jurassic). The fossil assemblage consists of terrestrial plants, invertebrates (bivalves, gastropods, decapod crustaceans, isopods and insect larvae) vertebrates (fishes). This study takes fishes, crustaceans into account, giving systematic, taphonomic palaeoenvironmental considerations. land flora impressions...
Abstract The origin and early diversification of decapod crustaceans their expansion from marine to continental environments are key events in arthropod evolution. Rare fossil decapods known the Palaeozoic, earliest eumalacostracans with undoubted affinities L ate D evonian P alaeopalaemon A ciculopoda , found offshore deposits. Here, we describe a new species shrimp T ealliocaris floodplain temporary pond deposits F amennian ( evonian) B elgium, together rare alaeozoic assemblage other...
Dendrobranchiate shrimps are abundant in Fossil-Lagerstätten (where fossils exceptionally preserved). Despite their preservation, classifying them can be challenging as most diagnostic characters based upon extant species. Penaeus natatorGlaessner, 1945 (Late Cretaceous, Lebanon, Sahel Alma), is one of those cases which the systematic assignment species difficult. It was assigned by “default” to Fabricius, 1798, before being moved Metapenaeopsis Bouvier, 1905. The recent description...
The Middle Jurassic La Voulte-sur-Rhône Lagerstätte preserves with remarkable details a highly diversified bathyal palaeocommunity dominated by arthropods. Polychelida Scholtz & Richter, 1995 are particularly abundant and currently represented Eryon ellipticus Van Straelen, 1923, Proeryon giganteus (Van 1923), Hellerocaris falloti Willemoesiocaris ovalis 1923). This new investigation reveals the presence of two genera three species in this crustacean community: Voulteryon parvulus n. gen.,...
