PALEOPEDOLOGY AND TAPHONOMY OF THE BRIAN MABIUS SITE, BADLANDS NATIONAL PARK, SOUTH DAKOTA
Taphonomically, the BM Site contains many various specimens of weakly to moderately weathered, disarticulated, carnivore processed, and mostly random oriented vertebrate fossils that are adjacent and laterally traceable to the Haplustalfs and Haplustepts. These taphonomic indicators imply that drought and/or predators proximal to a lacustrine (oxbow) setting terminated these Orellan taxa where periodic seasonal flooding events transported and buried faunal remains. This is different than the Pig Dig Site, where faunal accumulation is due to drought.
This research is apart of a program sponsored by the National Park Service to document and protect fossil resources within Badlands National Park. Detailed analyses of sedimentology, paleopedology, stratigraphic position, and geographic distribution of fossil sites will help to derive models to predict new sites and to interpret the effect of basin dynamics on bone bed genesis which will aid in protecting them from poaching.
