Morphology, Classification and Life Habits of the Productoidea (Brachiopoda)

Sedimentary context and palaeoecology of Gigantoproductus shell beds in the Mississippian Eyam Limestone Formation, Derbyshire carbonate platform, central England

“…The genus Gigantoproductus contains the largest brachiopod specimens ever recorded (Muir-Wood & Cooper 1960) and these most commonly occur in shell beds or lenses (Ferguson 1978;Angiolini et al 2012;Yao et al 2016). Gigantoproductus is distinguished by its large size, shallow corpus cavity, irregular ribbing and fluting, and the occurrence of dorsal brachial cones (Pattison 1981;Brunton et al 2000).…”

Royseux: a palaeobiodiversity hotspot in the Late Viséan (Carboniferous) of Belgium

“…plate 1, figures 1-4; Mottequin et al, 2015a, figure 13A), which was interpreted as being preserved in a relatively low energy environment with turbiditic sedimentation. As explained by Muir- Wood & Cooper (1960) for representatives of the genus Antiquatonia characterised by long trail, it is supposed that the posterior part of the shell was partly buried in carbonate mud with the trail protruding, and thus the hinge and ear spines served to anchor the shell. In contrast, representatives of the Subfamily Gigantoproductinae were devoid of such long hinge spines, but these very large-sized shells, with shelly thickening in their posterior part, were characterised by a thick and prominent ventral umbo that lay in the soft sediment with the long trail extending obliquely upward according to MuirWood & Cooper (1960).…”

“…So far, only a small number of these many species has been revised (e.g. Muir-Wood & Cooper, 1960;Brunton et al, 1994). Demanet (1958) recorded 26 species in the former 'V3b' unit of the Yvoir area (Dinant sedimentation area), i.e.…”

A Boreal-type brachiopod species, <i>Waagenoconcha irginae</i> (Stuckenberg), from the middle Permian (Wordian) of the South Kitakami Belt, Japan

“…Waagenoconcha irginae is known from the lower and middle Permian (Asselian Capitanian) of Spitsbergen (Gobbett, 1963), Kanin Peninsula, Pechora Basin, Timan, northern Urals and Kolyma in northern Russia (Solomina, 1960;Zavodowsky and Stepanov, 1970;Ifanova, 1972;Kalashnikov, 1986Kalashnikov, , 1993, southern Urals in central Russia (Stuckenberg, 1898;Tschernyschew, 1902;Muir-Wood and Cooper, 1960), southern Mongolia (Manankov, 1991), Inner Mongolia in northern China (Lee and Gu, 1976), South Primorye in eastern Russia (Fredericks, 1925), Hida Gaien Belt in central Japan (Tazawa, 2001) and South Kitakami Belt in northeastern Japan (Tazawa, 1974;Tazawa and Ibaraki, 2001; Tazawa and Araki, this study). It is noteworthy that the geographical distribution of W. irginae is restricted in the Boreal region (Spitsbergen and northern Russia) and the transitional (boundary) zone between Boreal and Tethyan realms (southern Urals, southern Mongolia, northern China, South Primorye, Hida Gaien and South Kitakami), and have never been recorded from South China (eastern, centralsouthern and southwestern China) (Fig.…”

“…Waagenoconcha is an antitropical productoid brachiopod genus, distributed in the Upper Carboniferous upper Permian, mostly in the lower and middle Permian, of both Boreal and Gondwanan regions and their surrounding areas (Muir-Wood and Cooper, 1960;Grant, 1966;Nakamura and Tazawa, 1990;Brunton et al, 2000). Waagenoconcha irginae is known from the lower and middle Permian (Asselian Capitanian) of Spitsbergen (Gobbett, 1963), Kanin Peninsula, Pechora Basin, Timan, northern Urals and Kolyma in northern Russia (Solomina, 1960;Zavodowsky and Stepanov, 1970;Ifanova, 1972;Kalashnikov, 1986Kalashnikov, , 1993, southern Urals in central Russia (Stuckenberg, 1898;Tschernyschew, 1902;Muir-Wood and Cooper, 1960), southern Mongolia (Manankov, 1991), Inner Mongolia in northern China (Lee and Gu, 1976), South Primorye in eastern Russia (Fredericks, 1925), Hida Gaien Belt in central Japan (Tazawa, 2001) and South Kitakami Belt in northeastern Japan (Tazawa, 1974;Tazawa and Ibaraki, 2001; Tazawa and Araki, this study).…”
