Abstract: For the first time, the same fish species is recorded from Triassic rocks at both ends of the Tethys, namely, Thoracopterus wushaensis Tintori et al., 2012. First described from the southwestern China Xingyi Fauna (late Ladinian, Middle Triassic), it is now also known from a coeval site in the Dolomites in northern Italy. T. wushaensis is considered a flying fish, owing to its elongated pectoral and pelvic fins, tail with a ventral lobe much larger than the dorsal one, and peculiar enlarged neural spines in the caudal region. Taxonomical problems among Peltopleuriformes are also discussed on the basis of an improved comparison between eastern and western Tethys fish assemblages. This finding bolsters the marine vertebrate similarity between China and Europe during the Middle Triassic. Furthermore, because T. wushaensis from the Pelsa/Vazzoler is part of a very rich assemblage yielding several fishes, and also dozens of invertebrate taxa, it also supports the hypothesis of a global bioevent among marine fauna during the late Ladinian, well before the San Cassiano Fauna or the Carnian Pluvial Episode.
