Ponor Quarry, Anina (Jurassic of Romania)

Where: Romania (45.1° N, 21.9° E: paleocoordinates 25.2° N, 25.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Uteris Member (Steierdorf Formation), Pliensbachian (190.8 - 182.7 Ma)

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; lithified, carbonaceous shale

• Stănoiu et al. (1997) refined the stratigraphy of the Reşiţa Basin, considering Uteriş as a distinct formation, probably due to its very peculiar lithology. For this unit they consider a restricted lacustrine system as paleoenvironment. However, Popa (2000 a) does not exclude even a possible marine origin.

Size class: macrofossils

Collection methods: Repository: Vertebrate Paleontology collection at Paleontology-Stratigraphy Museum, Babes-Bolyai University Cluj. (P.S.M.U.B.B.)

•Collected by: A team of geologists from "Babes-Bolyai" University in Cluj, in a field mission carried out some years ago.
