“…Norian-Rhaetian hypercalciWed sponges of the Tethys domain are known from numerous localities in the western (Northern Calcareous Alps, Southern Alps, Carpathians, Apennines, Sicily, Greece: see Senowbari-Daryan and García-Bellido 2002), northern Tethys (Caucasia, Pamir Mountains : Boiko 1979;Boiko in Boiko et al 1991), southern Tethys (India: Bhargava and Bassi 1985;Oman: Bernecker 1996, 2005 and central or eastern Tethys (Iran: Senowbari-Daryan 2003, 2005aSenowbari-Daryan and Hamedani 1999;Senowbari-Daryan et al 1997;Timor: Vinassa de Regny 1915;Maluku Islands: Wilckens 1937; Wombat Plateau, northwest Australia: Röhl et al 1991).

SupercalciWed sponges, including sphinctozoans, inozoans, chaetetids, spongiomorphids, occurring in Upper Triassic (Norian-Rhaetian) shallow-marine limestones of Musandam Mountains in United Arab Emirates (UAE), are described. The following taxa were determined: sphinctozoans: Hajarispongia osmani Senowbari-Daryan and Yancey, Nevadathalamia arabica n. sp., Nevadathalamia conica n. sp., Fanthalamia milahaensis n. sp., Iranothalamia incrustans (Boiko), Cinnabaria regularis n. sp.; inozoans: Cavsonella triassica n. sp., MolengraaYa regularis Vinassa de Regny, Peronidella? sp., Circopora cf. caucasica Moiseev, Circopora? sp.; spongiomorphids: Spongiomorpha sp.; chaetetids: Lovcenipora chaetetiformis Vinassa de Regny, Lovcenipora musandamensis n. sp., Lovcenipora sp., chaetetid sponge gen. et sp. indet. The most abundant sponge in the studied material is Nevadathalamia arabica n. sp. The described sponge association of the Arabian shelf (Musandam Mountains) shows close aYnity to the sponge association known from age-equivalent terranes in the Panthalassa Ocean (Sonora Mountains in Mexico; Pilot Mountains in Nevada, USA), but is remarkably diVerent from sponge associations in carbonates bordering the Tethys. This diVerence goes along with the biogeography of wallowaconchid bivalves and is most likely attributed to climatic, palaeogeographic or oceanographic factors.

“…They are known from numerous localities throughout the world, in particular the Tethys seaway, Cordilleran terranes, and cratonal North America (Panthalassan Ocean). Western Tethys localities include Austria, northera Italy, Hungary, and Slovenia in the Alps (Flügel, 1981(Flügel, , 2002Flügel and Senowbari-Daryan, 2001); the southern Tethys from Sicily (Senowbari-Daryan, 1980, 1990Senowbari-Daryan and Schäfer, 1986), Turkey (Senowbari-Daryan, 1994a), and Oman (Bernecker, 1986); the northern Tethys at Caucasus (Moissev, 1944;Boiko et al, 1991); central Tethys (Iran: Senowbari- Daryan, 1996Daryan, , 2005aDaryan, , 2005bSenowbari-Daryan et al, 1997); and eastern Tethys (Wilckens, 1937;Röhl et al, 1991).…”

The first Upper Triassic silicified hypercalcified sponges from the Alexander Terrane, Gravina island and Keku Strait, Southeast Alaska

This paper describes the first silicified Upper Triassic (Early Norian) hypercalcified sponges known from the Alexander terrane, southeast Alaska. Sponges consist of five taxa from the Cornwallis Limestone of Keku Strait, southeast Alaska: Amblysiphonella Steinmann, Parauvanella Senowbari-Daryan and Di Stefano, Nevadathalamia cylindrica (Seilacher), N. minima n. sp., and Stellispongia (S. cf. subsphaerica Dieci, Antonacci, and Zardini). The hypercalcified sponges of the Alexander terrane as described in this paper provide paleogeographic linkage with other far-flung terranes of western North America, namely the Western Great Basin of Nevada, Stikinia of the Yukon, as well as the Antimonio terrane of northwestern Mexico. In addition, Parauvanella cf. ferdowensis is known from the Upper Triassic Nayband Formation, Iran. Finally Stellispongia cf. subsphaerica is known from the Upper Carnian Cassian Formation of the Dolomite Alps.Sponges (particularly hypercalcified inozoans, sphinctozoans, chaetetids, and sponge-like organisms) are known worldwide from many Upper Triassic reef and nonreef sites. Although Upper Triassic deposits within the Cordilleran terranes and cratonal North America do not typically contain reeflike buildups, hypercalcifying sponge-like organisms were noted as occurring as part of the intricate paleoecological structure within a biostrome along the western shoreline of Gravina Island, southeast Alaska (southern Alexander terrane). This is in contrast to Keku Strait, southeast Alaska (central Alexander terrane), where hypercalcified sponges were identified from limestone beds within nonreef deposits.
