What are some extinct animals of Wisconsin?

I need to know some animals that are extinct in Wisconsin. It's for my homework/paper due tomorrow so I kind of need the info ASAP. You know? and when you leave an answer, could you tell me your source? I wouldn't know how to cite a person yet....especially from the internet. Thank You!

1. Trilobites devonian fishes(placederms), eurypterids, tons of coral species, i could go on forever.... Search Devonian, Silurian, Mesozoic etc.. you'll likely have better luck if you search geological ages.
