Grossberg Bank
Basic information
Sample name: Grossberg Bank
Sample aka: Laubenheim

Reference: J. J. Brinkkötter and T. Martin. 2015. Small mammals and stratigraphic position of the "Grossberg-Bank" (lower Oberrad Formation, MN1, early Miocene) at Laubenheim Quarry in the Mainz Basin, SW Germany, and their implications for early Miocene biostratigraphy. Paläontologische Zeitschrift 89:995-1022 [ER 2395]
Country: Germany

Coordinate: 49° 57' N, 8° 19' E
Basis of coordinate: based on nearby landmark
Geography comments: "southeast of the center of Mainz within the districts Mainz-Weisenau, Mainz-Laubenheim, and Mainz-Hechtsheim... in the Laubenheim quarry" (coordinate based on Mainz-Laubenheim)
in "the lower Oberrad Formation... presumably of Aquitanian (Lower Miocene)" based on biostratigraphy of multiple taxa; "uppermost MN1" based on the mammals themselves
Climate and habitat
Substrate: ground surface
Lithology: marl
Habitat comments: "light to brownish gray, unstratified Hydrobia marl... floating cadavers" were "delivered by rivers from the hinterland of the Mainz Basin lagoon" (i.e., the greater environmental context is a lagoon)
Life forms: rodents, other small mammals
Sampling methods: screenwash, surface
Sample size: 55
Sampling comments: "Apart from brackish-marine invertebrates and aquatic vertebrates" the sample "yielded a large number of disarticulated bones, mandibles, and teeth of terrestrial vertebrates such as reptiles, birds, and mammals" (lagomorphs, ungulates, and carnivorans are listed but not described)
"The material was collected predominantly on the surface of the fossiliferous bed... a few kilograms of sediment" were collected "from the fossiliferous layer for extraction of microvertebrates" (presumably using screening)
