by one of us (AV); these identifications are included in the present work. The profuse brachiopod faunas of the western Gerecse Mountains (Asszony-hegy, Nagysomlyó, Hosszúvontató, Teke-hegy) were described and illustrated in details by G. VlGH (1943). Recently we made new collections in many localities and partly revised VlGH's identifications (DULAI 1998a, 1998b, 2003). In the Pilis Mountains, the neptunian dykes at Kétágúhegy provided rich faunas which were described, but not illustrated, by GY. VlGH (1913). We re-examined the brachiopods housed in the Museum of the Hungarian Geological Institute. The above faunas are usually very rich but the old bulk collections are not precisely dated by ammonoids, therefore they are regarded generally as Sinemurian without attribution to substage. The Sinemurian brachiopods of the Bakony Mountains are more precisely dated, therefore their division into an Early and a Late Sinemurian association is possible. Ammonoid stratigraphy was developed only in a few Ljower Sinemurian sections (Lókúti-domb: GÉCZY 1972a, Márkó, Som-hegy: DULAI 2002). At these localities, detailed collection for brachiopods was carried out. The Lower Sinemurian Pisznice Limestone (Lókúti-domb: DULAI 1990, 1992) yielded 400 specimens, whereas from the Isztimér Formation (Márkó, Som-hegy: DULAI 2002, 2003) 800 specimens were collected. Most of the typical Hierlatz Limestone occurrences are attributed to the Upper Sinemurian, partly on the basis of ammonoids (Szentgál, Tűzköves-hegy: GÉCZY 1974; Olaszfalu, Eperkéshegy: GÉCZY, pers. comm.). Some other, very abundant "Hierlatz-type faunas" (Úrkút, Csárda-hegy; Porva, Kékheg}') were arbitrarily inferred as Upper Sinemurian by considering lithological and faunal analogies. Nearly 10,000 brachiopod specimens have been collected from these localities and are kept in the collections of the Hungarian Natural History Museum. Here we present a summarized list of the Sinemurian brachiopods, while in range chart (Figure 2) the Early and Late Sinemurian occurrences are distinguished.
