T. Bolliger, Foot prints of vertebrates (? Amphicyonidae, Mammalia) from the basal Upper Freshwater Molasse (OSM) of the canton Lucerne, ECLOG GEOL, 91(3), 1998, pp. 541-547
Two vertebrate footprints from sediments of the Upper Freshwatermolasse of
Central Switzerland are presented. Lithology and indications concerning pal
eoecological conditions are described. Finally, the trackways are character
ized, and their possible producers are discussed. Most probably, the trackw
ay causing animals were amphicyonids (Mammalia: Carnivora). These animals w
ere abundant predators at that time.
