My dad and I were on vacation in Wisconsin when we came across this apparently dead life form.

We were on the banks of a freshwater river (forgive me, I don’t know the name of the river). The pics aren’t that good, they were taking in 1984. We’ve always wondered what the heck this thing is.

The insides were a clear membrane while the outside was a tougher almost scaly rind. It did not smell, so I’m guessing it died recently.
