Paradox lost: wide gape in the Ordovician brachiopod <i>Rafinesquina</i> explains how unattached filter‐feeding strophomenoids thrived on muddy substrates Open
Strophomenoid brachiopods had thin, concavo‐convex shells, were ubiquitous colonizers of Palaeozoic muddy seafloors, and are hypothesized to have filter‐fed in a concave‐upward orientation. This orientation would elevate their line of comm…

‘Jumping’ attack strikes by the predatory marine snail Agaronia propatula (Caenogastropoda: Olividae) Open
The gastropod Agaronia propatula (Olividae) forages on the sandy beach intertidal of the central American Pacific coast. Agaronia resembles subtidal Oliva spp. morphologically and behaviourally. While both genera seize prey by rapid moveme…

Feeding behaviour and the operculum in Olividae (Gastropoda): the case of Callianax biplicata (G. B. Sowerby I, 1825) Open
Olividae are marine gastropods living as predators or scavengers on soft sediments. The complex prey handling behaviour of large predatory species includes the storage of food in a pouch formed temporarily by bending and contraction of the…

Sequence stratigraphic model for repeated “butter shale” Lagerstätten in the Ordovician (Katian) of the Cincinnati, Ohio region, USA Open
The “butter shale” Lagerstätten of the Cincinnati Arch have produced an abundance of articulated trilobites, along with assorted bivalves and cephalopods. These bluish gray shales are rich in clay, poorly calcified, and show vague internal…

The ups and downs of<i>Diplocraterion</i>in the Glen Rose Formation (Lower Cretaceous), Dinosaur Valley State Park, Texas (USA) Open
Diplocraterion, a U-shaped burrow attributed to infaunal invertebrates, is normally a shallow-marine trace fossil and not part of a continental vertebrate ichnoassemblage. Hence, the Glen Rose Formation (Aptian–Albian) of Texas (USA) prese…

Calibrating water depths of Ordovician communities: lithological and ecological controls on depositional gradients in Upper Ordovician strata of southern Ohio and north-central Kentucky, USA; pp. 19–23 Open
Limestone and shale facies of the Upper Ordovician Grant Lake Formation (Katian: Cincinnatian, Maysvillian) are well exposed in the Cincinnati Arch region of southern Ohio and north-central Kentucky, USA. These rocks record a gradual chang…

Preliminary report on the Oldenburg “butter shale” in the Upper Ordovician (Katian; Richmondian) Waynesville Formation, USA; pp. 3–7 Open
The Cincinnatian Series (Upper Ordovician; upper Katian) of the Cincinnati Arch region, Ohio, Indiana and Kentucky) contains several bed packages informally referred to as âbutter shalesâ or âtrilobite shalesâ. These packages are t…
