Vremir, M., Codrea, V. ; Farkas, B.: Trionyx stiriacus Peters, 1855 (Reptilia, Testudines) from the Sarmatian (Middle Miocene) of Minişu de Sus (Romania)

Late Eocene of the Cluj-Giläu area. Early this century, LÖRENTHEY (1903) established 77. clav atomarginatus from the Priabonian coarse limestone exploited at that time in quarries located in the vicinity of Cluj, at Manas,tur and the Plesxa Valley. SZÁLAI (1932, 1934) also described a series of materials originating from Transylvania, reviewed subsequently by MLYNARSKI (1966) and FARKAS (1995). Finally, FUCHS (1962) contributed to the paleofaunistic knowledge of the Eggenburgian deposits of Coasta Mare near Cluj, as well as of Coruç, and noted the occurrence of the genus Trionyx. The present study aims at presenting materials curated in the collections of the Museum of the Transylvanian Basin, Babes-Bolyai University, Cluj-Napoca (MTB), and the Järii Cri^urilor Museum, Oradea (TCM), respectively.

HUMMEL, 1929 Genus Trionyx GEOFFROY ST.-HILAIRE, 1809 Trionyx stiriacus PETERS, 1855 Material: MTB 21636/1 - central-anterior fragment of a carapace, which makes the examination of its ventral surface possible, with P 1-7 dext., P 1-2 sin. and P 3-5 fragmentary, as well as an incomplete nuchal, and neural plates N 1-7; MTB 21636/2 - print of the same carapace, with plastral bones (hyo- and hypoplastron sin., xiphiplastron sin.) and endoskeletal elements (vertebrae, limb bones and elements of the scapular belt); MTB V-23 - fragment of a carapace representing the left half, partly with pleurals (P 3-5) and with a proximal hypoplastron dext. fragment; TCM 8377 - ventral print of an incomplete juvenile carapace with the caudal section missing. Locality: Mirii^u de Sus, Birzavita I quarry, upper level of the diatomite-tuffaceous complex, immediately below the andesitic agglomerate bed. Table 1.
