- Abstract
Constraints of time, personnel, and financial resources made it necessary to devise a system for rapid, salvage screen-washing of a heterogeneous mixture of unconsolidated fossiliferous sediments and intermixed, unrelated sediments from a Neogene continental sinkhole site in northern Indiana. USA. We constructed three sets of an apparatus that used a tractor to load large quantities of sediment into a soaking trough, after which the sediment was rapidly passed through coarse screens using power hoses. This set-up allowed recovery in a timely manner of large-vertebrate fossils from a large volume of mixed sediments that otherwise might never have been collected.
