Fossil Collecting Austria's Triassic Limestones
Manage episode 337243369 series 3380393
Fly with me over to Austria in Europe to visit the Hallstatt Limestones. These are the world's richest Triassic ammonite outcrops.
Along with diversified cephalopod fauna — orthoceratids, nautiloids, ammonoids — we also see gastropods, bivalves, especially the late Triassic pteriid bivalve Halobia (the halobiids), brachiopods, crinoids and a few corals. We also see a lovely selection of microfauna represented.
For microfauna, we see conodonts, foraminifera, sponge spicules, radiolaria, floating crinoids and holothurian sclerites — polyp-like, soft-bodied invertebrate echinozoans often referred to as sea cucumbers because of their similarities in size, elongate shape, and tough skin over a soft interior.
