Dinosaur Fish Lurk in Wisconsin Waters Believe it or not, the
gnarly, bottom-dwelling lake sturgeon first appeared on the face
of the earth about 150 million years ago - when the dinosaurs
were still around! Lake Sturgeon can still be found in Wisconsin
today. Look closely at the picture and you'll see that sturgeon
even look like prehistoric dinosaur fish. Their tail is shark-
like with the upper part longer than the lower and their long
slate gray/black shape is covered with sharp bony plates all
over. If you want to find sturgeon, look along Wisconsin's major
river systems, especially the Lake Winnebago waterway system
which holds the largest single concentration of sturgeon in the
world. You will also find them along the northern tip of the
Wisconsin River, the Mississippi, lower Wisconsin, Chippewa,
Flambeau, Manitowish, and Menominee Rivers. Actually, the
Wolf/Fox River is thought to be the only place in North America
where these spectacular fish can be seen when they spawn in late
April into early May.
