The picture shows Discotropites cf. sandlingensis. It was found at the classic Mons Tuval site situated at the Austrian /Bavarian border region south of Salzburg. Size of the ammonoid is about 7cm. This area of the world boasts one of the richest deposits of Triassic ammonite units — more than five hundred magnificent ammonite species are found here along with a diversified selection of cephalopod fauna — orthoceratids, nautiloids, ammonoids — we also see gastropods, bivalves (esp. halobiids), brachiopods, crinoids and a few corals. For microfauna, we see conodonts, foraminifera, sponge spicules, radiolaria, floating crinoids and holothurian sclerites — polyp-like, soft-bodied "wormy" invertebrate echinozoans.
