“…The presented material notably improves the Early Triassic record of fishes from the United States and provides new information on low-latitude vertebrate faunas during the essentially warm Early Triassic Romano et al, 2013). One of the presented fossils is derived from strata of Spathian age, thus adding a new occurrence to this interval.…”

“…The Smithian material studied here includes two largesized individuals of the predatory actinopterygian Birgeria, providing the first fossil evidence that birgeriids expanded their distribution into the western USA Sea, even during the Smithian thermal maximum Romano et al, 2013). One specimen can be ascribed to a new species, Birgeria americana n.…”

Abstract.-The Early Triassic vertebrate record from low paleolatitudes is spotty, which led to the notion of an 'equatorial vertebrate eclipse' during the Smithian. Here we present articulated ray-finned fishes (Actinopterygii), collected from the marine Lower Triassic Thaynes Group at three new localities in Elko County (Nevada, USA), which were deposited within the equatorial zone. From the Smithian of the Winecup Ranch, we describe two partial skulls of the predatory actinopterygian Birgeria (Birgeriidae), attributed to B. americana new species and Birgeria sp. Birgeria americana n. sp. is distinguished from other species by a less reduced operculogular series. With an estimated total length of 1.72-1.85 m, it is among the largest birgeriids. We confirm that Birgeria encompasses species with either two or three rows of teeth on the maxilla and dentary, and suggest that species with three well-developed rows are restricted to the Early Triassic. From the latest Smithian of Palomino Ridge, we present a three-dimensional, partial skull of the longirostrine predator Saurichthys (Saurichthyidae). This and other occurrences indicate that saurichthyids were common in the western USA basin. From the early late Spathian of Crittenden Springs, we describe a posterior body portion (Actinopterygii indet.). This find is important given the paucity of Spathian osteichthyan sites. We provide a summary of Early Triassic vertebrate occurrences in the United States, concluding that vertebrate fossils remain largely unstudied. The presence of predatory vertebrates in subequatorial latitudes during the Smithian confirms that Early Triassic trophic chains were not shortened and contradicts the 'equatorial vertebrate eclipse'.

“…Generally, Bellerophontoidea cross the Paleozoic-Mesozoic boundary with several genera (see Kaim & Nützel 2011). In the Early Triassic, they are globally distributed and locally abundant but became extinct during the Smithian (Kaim & Nützel 2011) as part of a larger Smithian extinction event (Romano et al 2012).…”

Five gastropod species are described from the Early Triassic (Smithian, Spathian) of the Salt Range in Pakistan, which is the first detailed documentation of gastropods from this key area of the Palaeozoic-Mesozoic transition. Bellerophontoidea are represented by Warthia hisakatsui. Bellerophontoidea were widespread in the Paleozoic and had their last appearance in the early Smithian. Anisian and later reports of this group are discussed, but currently remain doubtful. Soleniscidae, a typical Late Palaeozoic caenogastropod family, are present with two new species: Strobeus batteni and S. pakistanensis. The neritimorph genus Naticopsis and the caenogastropod Coelostylina are present with one species each, provisionally treated in open nomenclature. Naticopsis? sp. shows preservation of original colour patterns, which is very rare in Early Triassic gastropods. All identified genera originated during the Paleozoic (perhaps with the exception of Coelostylina) and are thus survivors or holdovers. Warthia and Strobeus survived the end-Permian mass extinction but went extinct during the Smithian when environmental conditions deteriorated again

“…Sun et al, 2012;Romano et al, 2013, for more literature), the Transcaucasian and NW Iranian sections are known from fewer studies. Although sections in this region have attracted scientists for a long time (Abich, 1878;Frech and Arthaber, 1900;Bonnet and Bonnet, 1947), detailed lithostratigraphical and biostratigraphical studies of the Changhsingian sections in the Transcaucasus and NW Iran have only rarely been carried out.…”

Abstract. The Permian-Triassic boundary sections in northwestern Iran belong to the most complete successions, in which the largest mass extinction event in the history of the Earth can be studied. We investigated the Changhsingian stage in six sections in the area of Julfa (Aras Valley) for their lithology, conodonts and ammonoids. Revision of the biostratigraphy led to the separation of 10 conodont zones (from bottom to top Clarkina orientalis-C. subcarinata interval zone, C. subcarinata, C. changxingensis, C. bachmanni,
