The pond near my family home is too shallow for anything big to have drowned in it, but I'm sure it's full of dead turtles and the like. One of our old dogs liked to eat them.

It's also a popular hobby for some to go searching for fossils in the major river that runs through that area. They find some impressive stuff. Best I've ever seen has to be this leg bone from a juvenile mammoth (the collector also generously gave me some fossils because I think he was excited to see a young person at their club meeting, haha).
