... 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 deglaciation in North Africa. But in the Aeronian, reefs re-appeared almost on a worldwide basis, and with them the first atrypids specialized towards reef settings (e.g., the East Point reefs of Anticosti with Dihelictera and Septatrypa : Copper, 1995 ; Copper and Long, 1998 ; Copper, 2002a ). Further...

...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...

... atrypide brachiopods were selected from six beds in the Waterways Formation (latest Givetian – Early Frasnian; Alberta, Canada). The dorsal and ventral valves of each brachiopod were photographed. Sclerobiont taxa were mapped onto the photographs, and the maps were used to create stacked images with each...
