On the Geological Position of the Tertiary Strata of Sotzka, 

 Styria. By Dr. Fred. Eolle. 



[Proceed. Imp. Acad. Vienna, April 1858.] 



Two papers on the fauna and flora of the Tertiary beds at Sotzka, 

 near CiUy, in Southern Styria, have of late been published in the 

 Proceedings of the Imperial Academy of Vienna, the one by Prof. 

 C. von Ettingshausen, the other by Dr. F. EoUe. Prof. linger was 

 the first who published a monograph of the interesting fossil flora of 

 this locality (Transact. Imp. Acad. Vienna, 1851), which, on ac- 

 count of its decidedly tropical character and its near afiinity to the 

 present insular flora of Australasia, he declared to be of Eocene date. 

 Then, however, significative animal remains from the Sotzka strata 

 were unknown. Prof. IJnger's views on this subject did not remain 

 uncontradicted; the celebrated Leopold von Buch contended that 

 these deposits were of middle tertiary age ; and Prof. Heer has more 

 lately ranked them with the lower beds of the Swiss Molasse. 



Prof. C. von Ettingshausen, on examining in 1853 the Eocene flora 

 of Monte Promina (Dalmatia), found it to be highly concordant with 

 the fossil flora of Sotzka. According to his judgment, 38 species 

 among the 71 occurring at Monte Promina are also met with in the 

 fossil flora of Haring, and 34 in that of Sotzka. With the plants of 

 Monte Promina are associated characteristic animal forms, deter- 

 mined by Chev. von Hauer as JSferitina conoidea, Lam., Bostellaria 

 ftssurella, Lam., Diastoma costellata, Lam. sp., &c. These circum- 

 stances, together with the stratigraphical relations, prove the de- 

 posits of these three localities to be contemporaneous, and conse- 

 quently those of Sotzka to be somewhat older than Middle Tertiary. 



Prof. C. von Ettingshausen has published the result of his inves- 

 tigations in the Proceedings of the Vienna Acad. vol. xxviii. p. 545. 

 He found the majority of the Sotzka plants to agree with those of 

 Haring (Tyrol), Sagor (Camiola), and Monte Promina (Dalmatia) ; 

 and only a few of Miocene or IJpper Miocene character. He re- 

 gards therefore the fossil flora of Eadoboj (Croatia), Parschlug 

 (Styria), and others of similar character, to be of younger date 

 compared with the Sotzka deposits. 



Dr. Rolle (Proceedings, Vienna Acad. vol. xxx. p. 13, 1858) 

 gives a zoological complement to these investigations. Having in
