Data from: Carbonate shelf development and early Paleozoic benthic diversity in Baltica: A hierarchical diversity partitioning approach using brachiopod data
<p class="Text">The Ordovician–Silurian (~485–419 Ma) was a time of considerable evolutionary upheaval, encompassing both the largest evolutionary diversification and one of the first major mass extinctions. The Ordovician diversification coincided with global climatic cooling and paleocontinental collision, the ecological impacts of which were mediated by region-specific processes including substrate changes, biotic invasions, and tectonic movements. From the Sandbian–Katian (~453 Ma) onward, an extensive carbonate shelf developed in the eastern Baltic paleobasin in response to a tectonic shift to tropical latitudes and an increase in the abundance of calcareous macroorganisms. We quantify the contributions of environmental differentiation and temporal turnover to regional diversity through the Ordovician and Silurian, using brachiopod occurrences from the more shallow-water facies belts of the eastern Baltic paleobasin, an epicontinental sea on the Baltica paleocontinent. The results are consistent with carbonate shelf development as a driver of Ordovician regional diversification, both by enhancing broadscale differentiation between shallow- and deep-marine environments and by generating heterogeneous carbonate environments that allowed increasing numbers of brachiopod genera to coexist. However, temporal turnover also contributed significantly to apparent regional diversity, particularly in the Middle–Late Ordovician.</p>
Late Ordovician brachiopods from east-central Alaska, northwestern margin of Laurentia
<p>A Late Ordovician brachiopod fauna from the Black River quadrangle (D-1 1:63,360 scale) of east-central Alaska comprises taxa typical of the Late Ordovician brachiopod fauna in the pericratonic epeiric seas of Laurentia, including Hesperorthis pyramidalis, Plaesiomys occidentalis, Eoplectodonta sp., Holtehdalina sp., Leptaena sp., Brevilamnulella minuta n. sp., Tcherskidium tenuicostatum n. sp., Rhynchotrema iowense, and Whitfieldella sp. The presence of Plaesiomys occidentalis and Tcherskidium tenuicostata n. sp. indicates a latest Katian age by correlation with similar species in the Mackenzie Mountains, southern Manitoba, Anticosti Island, the American mid-continent, Kolyma, and Siberia. Cluster analysis based on 20 well-studied late Katian brachiopod faunas from various regions within Laurentia and elsewhere in other tectonic plates suggests that the small brachiopod faunule from Alaska has the strongest paleobiogeographic affinity with Laurentia, confirming that the Black River quadrangle of Alaska was part of Laurentia during the Late Ordovician.</p>

Data from: Late Ordovician and Early Silurian virgianid and stricklandioid brachiopods from North Greenland: Implications for a warm-water faunal province
<p>An unusually rich and diverse suite of virgianid brachiopods, hitherto poorly known, are systematically described here for the first time from the Ordovician–Silurian boundary interval (late Katian–Aeronian) of North Greenland. The Late Ordovician virgianids comprise typical taxa of the warm-water <em>Tcherskidium</em> fauna (e.g. <em>Tcherskidium tenuicostatum</em>, <em>Proconchidium schleyi</em>, <em>Holorhynchus giganteus</em>, and <em>Deloprosopus dawesi</em> sp. nov.). Among the early Silurian taxa, <em>Virgiana hursti </em>sp. nov. occurs as abundant shell beds, similar to other congeneric species in Laurentia, but has somewhat larger internal skeletal structures, albeit not as extravagantly developed as in the late Katian virgianids; <em>Boraeloides balderi</em> gen. et sp. nov. shows extreme thickening of shell wall and internal structures, approaching the extravagant calcification of Katian virgianids. The highly distinct mid-Aeronian stricklandioid brachiopod genus, <em>Kulumbella</em>, characterized by a shell with criss-cross (divaricate) ribbing, also occurs in North Greenland, represented by <em>K. heimdalli</em> sp. nov., which has the largest and most strongly biconvex shells for the genus. Palaeogeographically, the Late Ordovician virgianid fauna of Laurentia was highly distinct, confined to the low–mid tropical latitudes north of the palaeoequator. In comparison, the early Silurian (Rhuddanian) <em>Virgiana</em> and some related taxa in Laurentia spanned the tropics of both hemispheres, forming extensive shell beds in carbonate basins, although <em>Borealis</em> and <em>Borealoides </em>gen. nov. remained confined largely to the northern hemisphere, suggesting a certain level of provincialism extending into the earliest Silurian. The unusual abundance and richness of the virgianid faunas in North Greenland is likely explained by a palaeoecological preference for warm-water carbonate settings.</p>
Measurements of Silurian brachiopod specimens from the Pentland Hills, Scotland
<p>The abundant and diverse brachiopod fauna from the Silurian (upper Llandovery-lower Wenlock) rocks of the Pentland Hills is described within its geographical stratigraphical context. The majority of species are described in detail, discussed and illustrated. A total of 53 species attributable to the following superfamilies are present (numbers of species, including those in open nomenclature, in parentheses): Linguloidea (7), Craniopsoidea (1), Discinoidea (4), Strophomenoidea (9), Plectambonitoidea (2), Chonetoidea (1), Childiopsoidea (2), Skenidioidea (1), Dalmanelloidea (3), Pentameroidea (2), Rhynchonelloidea (4), Atrypoidea (4), Athyridoidea (5), Cyrtioidea (5) and Delthyridoidea (3). Five new species, <em>Leptaena eska</em>, <em>Isorthis</em> (<em>Ovalella</em>) <em>clarksoni</em>, <em>Dicoelosia</em> <em>paratenua, Oglupes scotia </em>and <em>Lissatrypa scotica</em>, are erected. Nevertheless in terms of abundance the fauna is dominated by individuals belonging to the Strophomenoidea, Plectambonitoidea and Dalmanelloidea. The composition of the fauna, its deeper-water setting associated with finer-grained siliciclastic substrates characterizes this Pentlandian biota.</p>

<p><span>A most diversified Wuchiapingian brachiopod fauna, which contains 57 species in 28 genera, is described from the Shuizhutang Formation at Liannan section, Guangdong province, southeastern China. Four new species are proposed. Among these 57 species, many of them have been fully described in recent papers and thus are only illustrated in the manuscript and described herein.</span></p>
Data from: The Anisian (Middle Triassic) brachiopods from the southern Qilian Mountains, north-western China
<p><span>The Anisian (Middle Triassic) witnessed the diversification of brachiopods after the Permian/Triassic (P/Tr) extinction. The Anisian brachiopod fauna from the southern Qilian Mountains in north-western China has the highest taxonomic diversity at the species level among coeval faunas worldwide. Nevertheless, many taxa from this remote region remain poorly defined and therefore require emendation. Here we describe 23 species (including two uncertain species) in 15 brachiopod genera based on well-preserved carbonate and silicified specimens collected from the Anisian Dajialian and Qieermagou formations in Tianjun, southern Qilian Mountains. Two new genera (<em>Crenulatomargus</em>, <em>Tianjunospina</em>) and six new species (<em>Costirhynchopsis</em> <em>xui</em>, <em>Crenulatomargus</em> <em>terebratuliformis</em>, <em>Schwagerispira</em> <em>elegans</em>, <em>Lepismatina</em>? <em>inusitata</em>, <em>Tianjunospina</em> <em>junheensis</em>, <em>Qilianoconcha</em> <em>circularis</em>) are erected. The diagnoses of <em>Triasorhynchia</em>, <em>Yangkongia</em>, <em>Sinucostella</em>, <em>Aequspiriferina</em>, <em>Qilianoconcha</em>, and <em>Parantiptychia</em> are emended. Besides, the genus <em>Eoantiptychia</em> and the family Triasorhynchiidae are regarded as junior synonyms of <em>Qilianoconcha</em> and Tetrarhynchiidae, respectively. Systematic description and taxonomic emendation show that 56 species (including seven uncertain species) in 26 genera are confirmed in the southern Qilian brachiopod fauna. Network analysis of 14 brachiopod faunas worldwide shows that six groups were detected during the Anisian (Qingyan, southern Qilian–western Qinling, Himalaya–northern Siberia, central Qinghai, New Zealand, and Europe/western Tethys). Compared with those from the western Tethys, the eastern Tethyan faunas are less allied to each other. Except for the assemblage from the adjacent western Qinling area, other coeval faunas have much lower affinities with the Qilian fauna.</span></p>
