Are There Any William Ameth Tusks in the East River?

The odds there are actually William Ameth Tusks in the East River? I think they're extremely slim. Richard Osborne co-wrote it with two other gentlemen, both one a paleontologist, one an archaeologist from Alaska. One said he vaguely remembers Osborne telling him about really damaged and crummy and like powdery remains in crates that might have been dumped in the river. That that might not have been unheard of at the time but nothing of any value.
