A diverse Tournaisian (Carboniferous, Mississippian) brachiopod fauna has been recorded within the stratotype of the tempestite-dominated Hook Head Formation at Hook Head, County Wexford (south-east Ireland). The Hook Head Formation (335 m thick), which mainly consists of interbedded limestones of tempestite origin and shales, deposited on a shelf–ramp and yielded a rich invertebrate fauna (crinoids, bryozoans, corals, etc.). Thirty-three brachiopod species, of which one is new (Rugosochonetes sleemani), assigned to 29 genera, have been recognized. The brachiopod fauna is dominated by productides and spire-bearers (athyridides, spiriferides, and spiriferinides) and shares strong similarities with those reported in Wales and southern Belgium (Namur–Dinant Basin), which derived from the same palaeogeographical context.

A brachiopod fauna from the uppermost part of the Tournaisian Tournai Formation (Belgium) contains an undetermined species of Crurithyris (Spiriferida, Ambocoeliidae), which displays numerous bored shells. About 8% of the 432 specimens with conjoined valves display single, small (≤ 1 mm) boreholes, which are smooth-sided, cylindrical or weakly conical, circular to slightly elliptical in plan view, perpendicular to the shell surface and generally complete. Of the 35 bored articulated specimens, 27 were drilled on the ventral valve. Most of the boreholes are located in the posterior half of the shell, and no case of edge-drilling has been observed. The boreholes were drilled by a predator, or possibly a parasite, which selected individuals greater than 2.5 mm long. Crurithyris sp. may have represented an attractive (in terms of energy cost) and easy target for a small-sized predator because of its thin shell and ornament of minute spines. [less ▲]

Brachiopods of the orders Strophomenida, Orthotetida, and Athyridida from the late middle Frasnian–early Famennian interval (hassi to triangularis conodont zones) in the Namur-Dinant Basin (southeastern margin of Laurussia; southern Belgium) are described. Nine genera and subgenera represented by 12 species are recognized here. One new genus, Retrorstrophia, and one new species, Douvillina area, are erected. Crinisarina stainbrooki is proposed to solve the homonymy between C. reticulata (Gosselet, 1877) and Cleiothyridina reticulata Stainbrook, 1947, the type species of Crinisarina Cooper and Dutro, 1982. A lectotype is selected and illustrated for C. reticulata. A new name is also proposed for Athyris reticulata Chen and Xu, 2000, which is assigned here to Crinisarina: C. shashishanensis nom. nov. In southern Belgium, the last representatives of the families Douvillinidae and Leptostrophiidae (Strophomenida) are from the Upper rhenana Zone (late Frasnian). Athyridid brachiopods, especially the representatives of the subfamily Cleiothyridininae constituted a significant part of the early Famennian recovery faunas with spiriferids and rhynchonellids, just after the late Frasnian mass extinction.

Four brachiopod species from the upper Givetian of Ferques are described of which two are new: Cupularostrum minimum n. sp. (Rhynchonellida) and Cleiothyridina blacourti n. sp. (Athyridida). The third, which is assigned to Stringocephalus aff. fontanus Veevers, 1959, corresponds after revision to S. sp. (in Brice & Loones 2002) pro parte. The fourth is Stringodiscus giganteus (Sowerby, 1840) which is recorded for the first time in France. Material originates mainly from the Couderousse Member of the Blacourt Formation, dated by conodonts from the “Middle-Upper varcus Zone”, but exclusively for S. aff. fontanus and St. giganteus. Some rare specimens of C. minimum and Cl. blacourti have been collected in the lower part of the Bastien Member, upper part of the Blacourt Formation. Cl. blacourti is very common in the upper Givetian of Ferques, so the genus Cleiothyridina appears as soon as the upper Givetian as in Spain and not in the Famennian as it is reported in the “Treatise revised” (Alvarez & Rong, 2002).

Brachiopods (Productida [except Chonetidina], Orthida, Athyridida, Spiriferida [Adolfiidae, Reticulariidae, Ambocoeliidae, Thomasariidae], and Spiriferinida) recovered in the interval, in terms of the standard conodont zonation, between the Palmatolepis hassi and P. triangularis zones (Late Middle Frasnian to Early Famennian) in the Namur-Dinant Basin (Belgium) are described. The orders and suborders investigated include 32 species: 21 are described in open nomenclature, seven are previously known, four are new of which three are assigned to previously known genera: Aulacella aggeris n. sp., Dicamara plutonis n. sp., and Warrenella (Warrenella) aquaealbae n. sp. Th e fourth species belonging to a newly defined genus: Neptunathyris buxi n. gen., n. sp. A major brachiopod faunal change occurs at the top of the P. rhenana Zone in southern Belgium, with the disappearance of most existing species in parallel with the deterioration of the oxygenation conditions preceding the Upper Kelwasser Event. Only an impoverished fauna (Lingulida, Chonetidina, Rhynchonellida) has been collected in the P. linguiformis Zone. The recovery of the Famennian brachiopods after the end-Frasnian biotic crisis was rapid in the basal Famennian but, despite their great abundance, their diversity was relatively low. New cosmopolitan genera appeared at this time especially among the rhynchonellids, athyridids and spiriferids with new species of pre-existing orthid and orthotetid genera. [less ▲]

The palaeoenvironment of the ‘black marble’ of Denée [Dinant sedimentation area (DSA), southern Belgium], included in the Molignée Formation of Lower Carboniferous (Viséan) age, is discussed. This fossil conservation deposit (‘fossil Lagerstätte’) yielded a rare but remarkably preserved macrofauna (including fishes, echinoderms and brachiopods). It developed in a confined intra-platform basin progressively filled by distal calcareous turbidites originating from the southward prograding shelf to the north. This basin was bordered to the south by a discontinuous barrier of Waulsortian mud mounds built against a major synsedimentary fault separating the DSA from the southern Avesnois sedimentation area (ASA). The alternations of laminated (‘black marble’ facies) and bioturbated (‘thick-bedded’ facies) lithofacies occurring within the Molignée Formation imply that the palaeoenvironment recorded several anoxic to dysoxic periods alternating with more oxygenated ones due to sea-level fluctuations of low magnitude and was strongly influenced by the basin architecture inherited from the late Tournaisian.

In the Namur–Dinant Basin (Belgium), the last Atrypida and Pentamerida originate from the top of the Upper Palmatolepis rhenana Zone (Late Frasnian). Within this biozone, their representatives belong to the genera Costatrypa, Desquamatia (Desquamatia), Radiatrypa, Spinatrypa (Spinatrypa), Spinatrypina (Spinatrypina?), Spinatrypina (Exatrypa), Waiotrypa, Iowatrypa and Metabolipa. No representative of these orders occurs within the Palmatolepis linguiformis Zone. The disappearance of the last pentamerids, mostly confined to reefal ecosystems, is clearly related to the end of the edification of the carbonate mounds; it precedes shortly the atrypid one. This event, resulting from a transgressive episode, which induces a progressive and dramatic deterioration of the oxygenation conditions, takes place firstly in the most distal zones of the Namur–Dinant Basin (southern border of the Dinant Synclinorium; Lower P. rhenana Zone). It is only recorded within the Upper P. rhenana Zone in the Philippeville Anticlinorium, the Vesdre area, and the northern flank of the Dinant Synclinorium. It would seem that the terebratulids were absent during the Famennian in this basin, probably due to inappropriate facies. Among the 13 species described or briefly discussed (Palmatolepis hassi to Upper P. rhenana zones), Pseudoatrypa godefroidi nov. sp. and Spinatrypina (Exatrypa) marmoris nov. sp. are proposed as new.

The fossils which De Koninck described and illustrated as members of the molluscan Class Scaphopoda have been reexamined. For the first time, photographs of these specimens are presented. Scaphopod shells show only a limited number of morphologic features and for most of these species, the details are lacking which would indicate that the fossils belong undoubtedly in the Scaphopoda. The study suggests that most of the named species may not be Scaphopoda; these species are assigned to informal groupings, ranging from Incertae sedis, through "worm tubes" to "probably Scaphopoda". Only one specimen may be identified without question as a member of the scaphopods. [less ▲]
