... and fairly diverse near the base of the Rhuddanian in deeper waters and rare further up, especially in the Aeronian. One new genus, Bockeliena , and two new species, Plectatrypa rindi and Euroatrypa ? sigridi are defined. The relationship between the subfamilies Spirigerininae and Plectatrypinae is clarified...

... of the shell clearly show no dorsal median septum or septalium in the dorsal valve, and no spiralia or atrypide-style crura. Like other species of the genus, A . tarimensis n. sp. exhibits a high degree of intraspecific variation, including variations in shell shape and size, number of ribs in the sulcus...

...A. C. Lenz Abstract The names Ogilviella and Davidsoniatrypa are proposed for two new atrypid brachiopods from Lower Devonian beds of Royal Creek, northern Yukon. Ogilviella, a carinatininiid from beds of Siegenian age, is a coarsely costate, rotund form with a pedicle fold and brachial sulcus...

.... They also suggested that the genus would be better classified under the subfamily Spirigerinidae alongside the similar early atrypides Eospirigerina , Boucot and Johnson, 1967 ; Qilianotryma Xu, 1979 ; and Sulcatospira Xu, 1979 . This is probably more appropriate, as Schachriomonia has separate...

... Meristelloidea), and considered Cryptothyrella as its junior synonym. The Rhuddanian (early Silurian) genus Koigia , common in Estonia and on Anticosti, was allocated to their new subfamily Whitfieldelllinae, to which they gave a range of Ashgill through late Silurian (Alvarez et al., 1998 , p. 836). Thus...

... restricted to the pedicle valve. However, other spine geometries also are prevalent, and the assumption that all arrangements functioned similarly may be unwarranted. Spinatrypa and Praewaagenoconcha , an atrypide and a productide, respectively, are genera of spinose brachiopods from the Upper Devonian Java...

... to species wherever possible, although genus-level identifications were common. Because the diagnostic characters used for distinguishing closely related taxa (e.g., Anazyga and Zygospira ) were not always visible in some samples, such taxa were lumped into coarser taxonomic units (e.g., atrypids) prior...

... brachiopods. The Steinbreche Quarry (loc. 20) originally exposed a ca. 15 m thick succession ( Jux 1964 ). Mass occurrences of atrypids, tabulates, and solitary (Thamnophyllum) and colonial ( Hexagonaria hexagona ) rugose corals made the outcrop famous. It is also the type locality of the ostracod genus...

... and Stringocephalus, adapted to reefal facies. Losses were particularly severe for the atrypids as shown by Copper [1998] . At the top of Givetian, facies were less favourable to development of reefs and correlatively terebratulids decreased while atrypids re-increased with some new genera. During the fourth...

... . The spinose atrypids were originally named Hystricina when Stainbrook (1945) defined the genus. In 1951, Stainbrook renamed the genus as Spinatrypa because Hystricina was pre-occupied ( Stainbrook, 1951 ). The original definition of the genus is still largely valid ( Copper, 1967b ). The difference...
