• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• STRATIGRAPHIC RELATIONS: From an unnamed lithstratigraphic unit, which is overlain by the Driester Series. AGE: Lochkovian, on the basis of stratigraphic position. STRATIGRAPHIC POSITION: From a 30 m thick succession of marls and reddish sandstones, which overlies the basal 2 m thick limestone.

Collected by Vascautanu

Collection methods: surface (in situ), mechanical, hydrochloric,

• COLLECTOR: Vascautanu, 1930's. REPOSITORY: The specimens are deposited in the vertebrate collection of the Laboratory of Paleontology at the University of Bucharest (LPB), and in the collections of the National Geological Museum, Bucharest (MNG). PREPARATION: prepared mechanically using a mounted needle under a ZEISS binocular microscope. Some of the specimens, whose structures were too delicate to

•withstand mechanical removal of the matrix, were prepared using diluted hydrochloric acid.
