S2502, Devils Point, Byers Peninsula (Jurassic to of Antarctica)

Where: Antarctica (62.7° S, 61.2° W: paleocoordinates 50.9° S, 36.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Devils Point Formation (Byers Group), Late/Upper Tithonian to Late/Upper Tithonian (150.8 - 140.2 Ma)

• The locality of the Devils Point area yielded one specimen defined as Haplophylloceras strigile (Blanford, 1864). One more ammonite has been collected and conditionally identified as Protancyloceras sp. indet. Based on that, we suggest late Tithonian–early Berriasian age for the rocks at the vicinity of Devils Point.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified mudstone

• Ammonite specimens were collected from the dark grey mudstones, intercalated between coarse-sandstone beds

Size class: macrofossils

Collection methods: Repository: Museum of Paleontology and Historical Geology (Sofia University "St. Kliment Ohridski")
