Dulai, A.: The Lower Sinemurian (Jurassic) brachiopod fauna of the Lókút Hill (Bakony Mts., Hungary). Preliminary results
geographical subspecies formation evolved even within such short distance (4-5 km). The only snag is that the transportation from the previously already existed plateau can not be precluded. Fig. 11. Geographical distribution of faunas similar to the Lókút's one. The size of circles is proportional to the species number of the faunas. ( £ >10 common species, ^ 6-10 common species, 4-5 common species) Stra.tigraphical evaluation - I have examined the distribution in time of the found species; its result can be summarized in 3 points: - I can fix the presence of the found 36 species in the Lower Sinemurian Bucklandi Zone. - Comparing with the information of ALMERAS (1964), who summarized the stratigraphical distribution of Liassic and Dogger brachiopods on the basis of literature data, I could correct the global ranges of three species ( Liospiriferina sicula , Linguithyris aspasia , Linguithyris linguata). - I also have compared it with the results of VÖRÖS (1983), who examined the stratigraphical distribution of Pliensbachian brachiopods of the Bakony Mountains. Common species are found in the two examined faunas, so their ranges in the Bakony Mountains include the Lower Sinemurian also.
