Okay, since we are in fact talking about whale skeletons or remnants in Michigan and not the North Sea (you threw me there for a minute), the situation is becoming somewhat clearer.
There HAVE been bits of whale found in odd places in Michigan. Remains of a finback whale (
Balaenoptera), a sperm whale (
Physeter), and a right whale (
Balaena). The first specimen was found back in the 1860's, and other bits have been found since. However, the remnants are really just pieces (a vertebra in one place, a couple of ribs in another, another rib somewhere else). In addition, whale teeth occasionally turn up on Michigan's beaches. Of course, no actual skeleton was found - just a very few random bones. Carbon 14 dating of samples by C.R. Harington produced ages that show relatively recent deposition: the sperm whale was less than 190 years old, the finback whale was 790 - 650 years old, and the right whale was dated as being between 810 and 690 years old.
I'd say this tends to show the "fossil whales" in Michigan, despite creationist claims to the contrary, are relatively recent. How they got there, of course, is another story - and one that has not been effectively answered (there are a bunch of theories, including human transport, Champlain Sea, post-glacial flooding, etc).
