Geography
Country: Hungary
Coordinate: 46.25° N, 18.50° E
Coordinate basis: stated in text
Formation: Hidas
Time interval: Middle Miocene
Zone: MN7/8
Max Ma: 13.5
Min Ma: 13.3
Geography comments: "Fossil findings point to the Late Badenian MN 7+8 Zone, which, together with the earlier results based on the marine mollusc fauna, narrows the age of the unit to ~13.5–13.3 Ma"
Environment
Lithology: not described
Taphonomic context: fluvial deposit
Habitat comments: "The formation is composed of alternating lignite, clay, marl, mollusc coquina and lime mud layers"
Methods
Life forms: salamanders,frogs,lizards,snakes,rodents
Sampling methods: screenwash
Sample size: 154 specimens
Sampling comments: "Two tons of sediment were collected from the fossiliferous level at the studied outcrop. They were air-dryed on textile in the sunshine and subsequently soaked in water and some H2O2. The samples were screen-washed using a sieve system with a 0.5 mm mesh size"
