American buys thylacine pelt at yard sale

Bill Warren paid five dollars for an old striped pelt at a yard sale. It turns out he bought what appears to be one of the few extant pelts from the thylacine, a dog-sized carnivorous marsupial believed extinct in 1936. Warren has no idea how old the pelt might be, beyond the fact the previous owner bought it 32 years ago. If genuine, it's worth thousands on dollars. One hitch: he can't sell it, because the US government has never taken the animal off the Endangered Species List.
