The studied corals have been collected from cores of boreholes located in the central part of the Polish Carpathian Foreland in the Dąbrowa Tarnowska–Szczucin area. The Jurassic complex in this area presents a continuous stratigraphic section from the Upper Callovian to Tithonian, locally passing to the Lower Cretaceous (Berriasian). Its thickness exceeds 1,100 m in this area. This complex is composed of marine, mainly shallow-water deposits. The corals occur within the upper part of the Upper Jurassic (Tithonian) deposits, almost entirely within the Swarzów Limestone Formation (= coral-algal limestone formation). This occurrence marks the northernmost extent of Tithonian shallow-water corals in Poland and one of the northernmost in Europe. 42 coral species (among them 14 in open nomenclature) were identified in deposits of this formation. They include two new species: Complexastrea magna and Complexastrea dabroviensis. All taxa, except one, belong to the order Scleractinia. The described assemblage displays a Late Jurassic character. The broader stratigraphic span is assigned to some species, which are quoted from the Middle Jurassic and some species lasted until the Early Cretaceous, Berriasian and/or Valanginian.

In the Lower Cretaceous (Urgonian) limestones of the Provence region (South France) shallow-water scleractinian corals are very common. This paper concentrates on corals from the suborder Microsolenina. They represent 34 taxa (including 5 new species) belonging to 14 genera from two families: Microsolenidae and Latomeandridae. This coral assemblage is representative for the late Early Cretaceous Tethyan realm but also shows some endemism. Its characteristic feature is the abundance of hydnophoroid specimens from the genus Hydnophoromeandraraea Morycowa. The Barremian–Early Aptian age of the studied corals is based on forami- nifera (mainly orbitolinids), dasycladale algae and rudists, and agrees with that of the whole studied coral fauna.

Actinaraeopsis ventosiana is a new scleractinian coral species from the Lower Cretaceous shallow- water limestones of the Mont Ventoux (Provence, SE France). To date only two Late Jurassic species of this genus have been known, i.e. Actinaraeopsis araneola Roniewicz and A. exilis Roniewicz. The new species shows some similarity to the Jurassic species A. araneola, but differs in microstructure details and morphometric parameters.

W pracy opisano nowy gatunek koralowca kolonijnego Actinaraeopsis ventosiana, pochodzącego z płytkowodnych wapieni górnobarremskich Prowansji (SE Francja). Dotychczas tylko dwa gatunki tego rodzaju są znane z jury górnej, A. araneola Roniewicz i A. exilis Roniewicz. Nowy gatunek Actinaraeopsis ventosiana wykazuje pewne podobieństwo do jurajskiego gatunku A. araneola, ale różni się od niego parametrami morfometrycznymi i szczegółami budowy mikrostrukturalnej szkieletu.

Scleractinian corals occurring scarcely in the Lower Kimmeridgian Actinostl'eon (=Lopha, =Alectryonia) shellbeds at Malogoszcz in the Holy Cross Mountains, Central Poland, are represented by abraded colonies densely riddled by rock-boring bivalves (Lithophaga inclusa Phillips, GastTOchaena sp.) and polychaetes (potamilla sp.). The taxonomically recognised specimens include C01nplexastrea bUJ'gundiae (de Blainville, 1830), D 'imorphocoenia sp., Ovalastrea caryophylloides (Goldfuss, 1826), and Thamnasteria graeilis (Miinster, 1826). AlI colonies are preserved in the form of hollows, the wall s of which bear moulds of coral calyces, and of bivalve and polychaete borings. Taking into account the structural features of shellbeds and their faunistic content (uprooted crinoids Apioerinites, dug-out deeply-infaunal bivalves), stormy agitation is postulated as a basic agent responsible for damaging AeUnostreon communities, and their associates. The studied corals are thought to have lived aside the Aetinostreon gardens, up on a muddy bottom, from where they have been stirred-up during the storm cataclysm, having been then abraded and riddled by rock-borers repeatedly until laid down in a shellbed and transferred in to the fossil record. The extremely shallow-water conditions, under which the ostreid Actinostreon has lived, suggest the typically opportunistic nature or the associated corals, the same as of Ovalastrea caryophylloides (Goldfuss, 1826) from oolitic shoals, and the only colony of which completes the coral assemblage of Malogoszcz. The opportunism or ali these corals differs them from the habit of hermatypie forms from coeval and Oxfordian patch-reef communities of the Holy Cross Mountains (ef. Roniewicz & Roniewicz 1968, 1971).
