Name:  Diplichnites with "Ripple Buster"

Geologic Age:  Cambrian
Stratigraphic detail:  Mount Simon Sandstone outlier
Location:  Krukowski Quarry near Mosinee, WI
Comments:  Popular conjecture is that Diplichnites is the trace of a wandering Myriapoda, which brings to mind an ancient centipede (Chilopoda). Given the spacing of these footprints, the centipede that made the tracks of the fossil to the right would have been an awesome predator - perhaps the terror of the Cambrian beach some 1/2 billion years ago.  This specimen also has a type of Diplichnites that have been noted to persistantly plow through the sand ripples, against the current, popularly dubbed "The Ripple Buster."  This Plate Measures approx. 24 1/2"x 15 1/4"x 1 1/2"
