Extinct preflood animals.

Have you been to Noah's Ark in Kentucky?

This along with the creation Evidence museum are the 2 most visit places on my list.
Great family road trip. You will learn a lot. These 2 places aren't government funded so you will be able to see and interact with things you'll never find in a traditional museum.
If you believe in God put this on your bucket list.
Just a couple of pics of animals that were fossilized and replicated for your viewing pleasure.
