The best studied example of the Mediterranean brachiopod province is the Pliensbachian fauna of the Bakony Mountains (Hungary). There the five most abundant genera are all smooth (Linguithyris, Securithyris, Apringia, Bakonyithyris, Pisirhynchia). These smooth genera represent different morphological types (sulcate, axiniform, uniplicate). Phylogenetically related forms are known from several evolutionary lineages of discontinuous record ranging from the Triassic to the Recent. The Triassic-Jurassic and the Neogene-Recent parts of these evolutionary lineages are represented by several genera, while in the Late Cretaceous-Paleogene interval they seemingly disappear, at least they have no record. The Recent relatives of the above Pliensbachian genera live mostly in the deep sea: three are shallow bathyal (200-400 m), three deep bathyal (800-1200 m) and three abyssal (2000-4500 m). The abyssal genera occur mainly in the East Pacific. The geographical distdbution of the bathyal genera shows peculiar features: they are more or less confined to the western sides of the great ocean basins (West Pacific, West Indian Ocean, Caribbean region) and they are "thalassobathyal", i.e., they are living on submarine plateaus, seamounts or island aprons and not on the continental slopes. This pattern, extrapolated to the past, shows good analogy with the Jurassic palaeogeographical model developed for the western part of the Tethys Ocean. It is hypothesized that smooth, mainly sulcate, articulate brachiopods flourished in the bathyal or even abyssal zones during the Palaeozoic; they were not refugees but formed well-adapted communities. This stable, conservative fauna may have survived the crises manifested in the shelf seas and, in cases of appropriate palaeogeographical situations, may have implanted its descendants to the shallow bathyal or even sublittoral regions of the western margins of the ocean basins. The Mediterranean microcontinent system at the western part of the Jurassic Tethys might have been such an invaded region. Correlation between plate tectonic changes of ocean/continent configurations, the presence of ocean basins closed on the west, and the occurrence of smooth articulate brachiopod groups in shallow bathyal to sublittoral settings collectively suggest that the deep-water forms invaded the shallow environments of the western Tethys in Early Mesozoic times and the W Pacific and W Indian Oceans in the Neogene. They stayed in the deep-sea reservoir when a circum-equatorial ocean existed in the Late Mesozoic. (c) 2005 Elsevier B.V. All rights reserved.

Beyond a serious decrease of species diversity, the extinction of the orders Spiriferidina and Athyridida is connected with this episode. The order Athyridida was represented by the family Koninckinidae in the Early Jurassic. The stratigraphical and geographical distribution of the three Early Jurassic koninckinid genera (Koninckella, Koninckodonta, Amphiclinodonta) shows a definite radiative pattern. The number of their nominal species increased from 2 to 17 from the Sinemurian to Early Toarcian; in the same time interval, their area increased from the Alpine region to the whole Mediterranean and the NW-European domains. This radiative evolution can be explained as the result of different factors: (1) morphological adaptation to muddy bottoms, (2) fundamental changes in the current pattern in the Tethys/Laurasian Seaway, and, possibly, (3) utilization of methane-based chemosynthesis as alternative food source. The radiation of koninckinids, leading from the cryptic habitats of the Tethyan rocky floors to the extensive muddy bottoms of the open European shelves, was abruptly terminated by the anoxic event in the Early Toarcian Falciferum Zone. The main causes of the extinction might be: (1) the excessive warming of Tethyan deep waters by thermohaline circulation, (2) the anoxic event, which was not survived by the spire-bearers, handicapped by their stiff, calcareous spiralia.

AB - The paleobiogeography of the Jurassic brachiopods of the Alpine-Carpathian region and adjacent areas is discussed on the basis of the distribution of ''distinctive taxa''. The Jurassic microplates of the western part of Tethys and the present-day ''terranes'' of the Alpine-Carpathian region are outlined and their relationships are discussed. The migration possibilities of the brachiopods in the Jurassic Tethys were controlled mainly by plate/microplate movements and by changes in the oceanic current system. The Mediterranean microcontinent, isolated from the European and African shelves by oceanic/deep-sea belts, was the homeland of the Mediterranean brachiopod province. In the course of the Jurassic, the Mediterranean microcontinent moved, as part of the African plate, away from Europe, the widening Alboran-Ligurian-Penninic oceanic belt became a barrier preventing migration of brachiopods. By the end of the Middle Jurassic the Tisza microplate detached from Europe and formed a ''stepping stone'' for brachiopod dispersal. At about the same time, the ''Hesperian Strait'' opened between the basins of the Tethys and the Central Atlantic. The opening of this strait resulted in a reorganization of the Tethyan current system. The westward flowing equatorial currents which made a turn in the western corner of Tethys in the first half of the Mesozoic, now ran to the west through the Hesperian Strait via the Central Atlantic to the Pacific. This change produced a new pattern in brachiopod distribution: the Mediterranean fauna successfully invaded the European shelf, at the same time the Mediterranean province became impoverished.
