Historically, footprint-bearing localities in eastern and western North America and southern Thuringia and northern Bavaria have played pivotal roles in Triassic archosaur footprint research. In a nearly complete sequence of formations and footprint-horizons in the Moenkopi Group (U.S.A.), Newark Supergroup (U.S.A. and Canada), and Buntsandstein, Muschelkalk, and Keuper groups (Olenekian to Nor...

W. Altermann writes: In their discussion of palaeotectonics and palaeogeography of Malay Peninsula, Harbury et al. propose an alternative interpretation to Sengor’s (1984) model of Triassic or early Jurassic collision of the Cimmerian (Sibumasu) block with the Indochina block in the east. Their interpretation depicts Malay Peninsula as part of Triassic and lower Jurassic Australian Gondwana. ...

The Permo-Triassic archosauromorph record is crucial to understand the impact of the Permo-Triassic mass extinction on the early evolution of the group and its subsequent dominance in Mesozoic terrestrial ecosystems. However, the Permo-Triassic archosauromorph record is still very poor in most continents and hampers the identification of global macroevolutionary patterns. Here we describe crani...

Triassic eclogite and blueschist facies rocks occur as a thrust sheet, 25-km long and over 2-km thick, in an Eocene fold-andthrust belt in northwest Turkey along the İzmir–Ankara suture. The thrust sheet consists mainly of metabasites with minor marble, phyllite and metachert, and rare lenses of serpentinite. The common blueschist facies mineral assemblage in the metabasites is sodic amphibole ...

The Permian-Triassic Mass Extinction (PTME) is the greatest biotic crisis of Phanerozoic. In terrestrial settings, PTME appears to have been diachronous and it has suggested that losses initiated before marine crisis. We examine organic carbon-isotope (?13Corg) geochemical proxies for environmental change in a palaeotropical wetland succession from southwest China. A newly constructed astronomi...

BACKGROUND Lacewings (insect order Neuroptera), known in the fossil record since the Early Permian, were most diverse in the Mesozoic. A dramatic variety of forms ranged in that time from large butterfly-like Kalligrammatidae to minute two-winged Dipteromantispidae. PRINCIPAL FINDINGS We describe the intriguing new neuropteran family Parakseneuridae fam. nov. with three new genera and 15 new ...

Rhynchosaurs were key herbivores over much of the world in Middle and Late Triassic, often dominating their faunas ecologically, success may relate to dentition. They show unique ankylothecodont mode tooth implantation, with deep roots embedded bone jaw low crowns that rapidly worn down use. During growth, main area oral food processing, located middle posterior portions occlusal surfaces jaws,...
