X-ray micro-tomography of Carboniferous stem-Dictyoptera: new insights into early insects.
Computer reconstructions of Archimylacris eggintoni, a Carboniferous stem-group dictyopteran ('roachoid'), are presented. A siderite-hosted specimen was scanned using high-resolution X-ray microtomography (µCT), and a 'virtual fossil' was created with a resolution of 17.7 µm. This has revealed the morphology in great detail, including adhesive limb structures indicative of climbing and speciali...
متن کاملSyncarid Crustaceans from the Montceau Lagerstätte (upper Carboniferous; France)
Key aspects of the morphology, autecology, systematics and taphonomy of the crustacean syncarids from the Montceau Lagerstätte (Upper Carboniferous, Stephanian B; France) are presented. Palaeocaris secretanae is the most abundant faunal element of the Montceau biota and shows striking morphological similarities with Palaeocaris typus from the Mazon Creek Lagerstätte (Westphalian D; Illinois, US...
متن کاملNew fossil fish microremains from the Upper Carboniferous of eastern North Greenland
The Moscovian of eastern North Greenland has yielded an assemblage dominated by teeth and dermal denticles of chondrichthyans with rarer teeth of actinopterygians. The rather poor preservation of the material precludes precise identification but the following taxa have been recorded: Adamantina foliacea, Bransonella spp., Denaea sp., “Stemmatias” simplex, Lagarodus specularis, Actinopterygii in...
متن کاملMiddle Devonian-Early Carboniferous Conodont Faunas from the Khoshyeilagh Formation, Alborz Mountains, North Iran
Conodonts of Khoshyeilagh Formation, the most complete section of Devonian rocks in the Alborz Mountains, northern Iran, has been studied, and subspecies of the genera Icriodus, Bipennatus, Polygnathus, Pelekysgnathus, Ancyrodella, Palmatolepis, Bispathodus, Scaphignathus, Clydagnathus, Gnathodus, Scaliognathus and Dollymae have been obtained from the studied section. The faunas indicate an Eif...
متن کاملFirst Eurypterid from Italy: a New Species of Adelophthalmus (chelicerata: Eurypterida) from the Upper Carboniferous
The first eurypterid known from Italy is described, as Adelophthalmus pi#ssii n. sp. It comes from the Upper Carboniferous of the Carnie Alps (Friuli, NE Italy). Relationships with related species are discussed. Adelophthalmids are the commonest eurypterids of the late Palaeozoic, at which time the disparity of the order was waning. The new record enhances our knowledge of addophthalmid distrib...
