Near Westfield in Marquette County, Wisconsin — The American Midwest (Great Lakes)
Footprints in the Sands of Time
During the Cambrian geological period, North America lay along the equator with Wisconsin in the southern tropics. A shallow sea covered most of the continent and tropical storms churned that sea as they do today in the Gulf of Mexico. The Cambrian seashores of Wisconsin were pounded by such storms countless times. Subsequently, the tropical landmass was rotated and moved north by continental drift to become present mid-latitude North America.

Paleontologists believe that the track maker was a large, slug-like animal without a skeleton, which fed by sucking microbes from damp sand as it crawled
