Smithian (Early Triassic) ammonoid faunas from exotic blocks from Oman: taxonomy and biochronology
Brühwiler, T; Bucher, H; Goudemand, N; Galfetti, T (2012). Smithian (Early Triassic) ammonoid faunas from exotic blocks from Oman: taxonomy and biochronology. Palaeontographica. Abteilung A: Palaeozoologie - Stratigraphie, 296(1-4):3-107.
Abstract
Ammonoid-rich exotic bocks of Hallstatt facies in Jebel Safra, in Wadi Musjah and at Baid (Oman Mountains) have yielded several well preserved and highly diversified Smithian (Early Triassic) ammonoid faunas (Baidites hermanni fauna, Rohillites omanensis fauna, Flemingites rursiradiatus fauna, Nammalites pilatoides fauna, Owenites koeneni fauna and Anasibirites multiformis fauna). The comparison of these assemblages with data from other Tethyan basins such as the Salt Range, Spiti, Tibet and South China shows that nearly all known Smithian ammonoid faunal assemblages are present in the exotic blocks from Oman. The new Oman data strengthens the remarkably uniform biogeographic distribution of the Smithian ammonoid faunas within the Tethys.
One new ammonoid family (Galfettitidae), five new genera (Baidites, Goudemandites, Lucasites, Omanites, Safraites), and twelve new species (Baidites hermanni, Galfettites kyrae, G. omani, Goudemandites sinensis, Kashmirites baidi, Lucasites involutus, L. evolutus, Omanites musjahensis, Paranannites baudi, Pseudaspidites planus, Rohillites omanensis, Safraites simplex) are described. Additionally, a new early Spathian (late Early Triassic) species (Procolumbites safraensis) is described.

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
