The origin of extant amphibians remains largely obscure, with only a few early Mesozoic stem taxa known, as opposed to much better fossil record from the mid-Jurassic on. In recent time, anurans have been traced back Early Triassic forms and caecilians Late Jurassic Eocaecilia, both which exemplify stepwise acquisition apomorphies. Yet most ancient stem-salamanders, known rocks, shed little light on clade. gap between salamanders other lissamphibians, well Paleozoic tetrapods, considerable....
ABSTRACT As a single stratigraphic source and site of high-fidelity vertebrate trackways superbly preserved skeletons, the Lower Permian Tambach Formation, lowermost unit Upper Rotliegend, Bromacker locality in middle part Thuringian Forest near Gotha, central Germany, provides unique opportunity matching late Paleozoic with their trackmakers. Here track-trackmaker association is firmly established between two species ichnogenus Ichniotherium, Ichniotherium cottae sphaerodactylum, skeletal...
Abstract Late Palaeozoic sediments in central Morocco and the High Atlas Mountains document development of this area during formation Mauretanide part Hercynian orogeny. Continental basins formed Stephanian Permian. Although scattered time, they provide valuable biogeographical climatic information for Mauretanides as a link between Variscides east, Appalachians west Karoo south. New blattid insects Souss Basin enable correlation to Early B. Furthermore, we oldest African tetrapod tracks (...
Abstract Tetrapod footprints are among the most common fossil remains in continental Permian strata and thus of biostratigraphic interest. Based on vertical distribution 13 best-known tetrapod ichnotaxa, three footprint biochrons suggested for period: (1) Dromopus – latest Carboniferous (approximately Gzhelian) to late Early Artinskian), representing ichnoassemblages dominated by tracks temnospondyls, reptiliomorphs, pelycosaurs early diapsids; (2) Erpetopus Kungurian) Middle Capitanian),...
Ichnotaxonomic revision of two extended sequences large tetrapod footprints from the Westphalian A Bochum Formation western Germany suggests assignment specimens to well-known Permo-Carboniferous ichnogenera Ichniotherium and Dimetropus.Trackway parameters imprint morphology strongly support basal diadectomorphs "pelycosaurian"-grade synapsid reptiles, respectively, as most likely trackmakers.The ichnofossils thereby extend first appearance these important groups tetrapods by about 5-10...
ABSTRACT Habitat partitioning and site fidelity of spawning grounds are well-documented phenomena in extant selachians, but little is known about the reproductive strategies their fossil relatives. Here we describe selachian fauna Middle to Late Triassic Madygen Formation southwestern Kyrgyzstan, Central Asia, based on several dozen tooth crowns egg capsules. The material assigned three new taxa: Lonchidion ferganensis, sp. nov., Palaeoxyris alterna, being teeth capsules hybodontid sharks,...
A nearly complete skull and associated osteoderms from the Middle/Upper Triassic Madygen Formation of Kyrgyzstan are referred to a new chroniosuchid genus species. The taxon is characterized by parabolic outline, pustular ornamentation, tabular-squamosal contact, marked postparietal embayments, lack an antorbital fontanelle. palate only preserved in part, showing broad palatines ectopterygoids. Presence preorbital fenestra characteristic osteoderm morphology synapomorphies shared with all...
An assemblage of abundant and well-preserved tetrapod footprints has been discovered in the Tanamert Member (T3) Triassic Timezgadiouine Formation (Argana basin, western High Atlas, Morocco). It is first fossil record from T3. Surfaces different localities show a uniform ichnofauna that consists chirotherian small lacertoid forms. The chirotherians are assigned to plexus Protochirotherium—Synaptichnium, their trackmakers interpreted as basal archosaurs. imprints close affinities with...
Diverse tetrapod track assemblages with Scoyenia invertebrate traces were discovered in the Triassic Timezgadiouine and Bigoudine formations of Argana Basin (Western High Atlas, Morocco). The ichnofossils occur alluvial plain sandstones mudstones Irohalène Member (T5) Tadart Ouadou (T6) considered Carnian-Norian age by vertebrate remains palynomorphs. Tetrapod footprints are assigned to Apatopus, Atreipus-Grallator, Eubrontes isp., Parachirotherium, cf. Parachirotherium postchirotherioides,...
The Val Gardena Formation of the Dolomites region in northern Italy preserves most significant assemblage Late Permian tetrapod footprints world. More than 120 years collecting resulted about 900 publicly accessible specimens from study area. This huge amount data is comprehensively revised light recent advances Palaeozoic – Early Mesozoic ichnofossils. According to our analyses, Sandstone includes tracks that can be assigned cf. Batrachichnus isp. (temnospondyl amphibian), Capitosauroides...
