Wisconsin Under the Sea: Life in Wisconsin during the Early Paleozoic
Travel back in time with UW-Richland geologist Dr. Norlene Emerson as she describes the watery world of Wisconsin during the early Paleozoic. Life in Wisconsin roughly 545-440 million years ago was very different from what we see today. At that time, Wisconsin was located in the southern hemisphere and was flooded by a warm, shallow, tropical sea. In small isolated areas where land was exposed above sea level, no life existed. While, on the other hand, life was thriving under the sea.
