Vertebr. Hung. XVIII. 1978. Historico-zoogeographical and ecological investigation of the subfossil vertebrate fauna of the Aggtelek Karst KORDOS, László ABSTRACT: Author examined in the Aggtelek Karst (N Hungary) 7 new excavated localities (Holocene) with vertebrate remains. Examinations revealed significant data to the chorology of the vertebrate fauna of the last 10-12,000 years. The significant climatic changes of the last 10,000 years (i.e. Holocene) have started those large-scale faunal changes during the Upper Pleistocene whose vertebrate animals were replaced by a new modern fauna. Now, in the Aggtelek Karst, which is a closed and well circumscribed area of our country, seven recently excavated localities yielding vertebrate remains can help us to gain- a more exact and thorough knowledge of this process. By investigating these remains the main features of the evolution of the presentday vertebrate fauna of the Aggtelek Karst can be outlined. These data afford a possibility to draw conclusions concerning to palaeoclimatological conditions as well as to the influence of man's remaking of nature as reflected in the vertebral remains of the various levels. Results Tücsök-lyuk Shaft Tücsök-lyuk Shaft lies 4 kms north of Jósvafő on the right side of Lófej Valley at 285 m a.s.l. (Fig. 1). The depth of this small shaft, developed in light-grey limestone intercalated Middle Triassic dolomite, is 11.5 m its length is 16.2 m (FEJÉRDY and HOLLY, 1960). The cave ends in a small chamber the floor of which is covered by soil and stone rubble fallen into it from the surface. The narrow corrosion-pipes of the chambers as well as its wall bearing solution-traces are filled up with a greyish yellow clay which had got there by an earlier solifluction. This clay contains vertebrate remains (Table 1). Besides bones the samples contained Gastropoda indet. , charcoal and quartz pebbles with a diameter of 1-3 mm. The exact age of the fauna together
