I'm reposting this so tohicknh2o and I can figure out if thispiece is worth bringing to a paleontology meeting we are going to on Thursday.
I was in Mantua NJ at the Inversand Marl pit today hunting for something good. I stumbled upon this odd looking thing. Looks almost as if someone used a drill bit because the hole in the center looks almost perfect. Measures roughly 2 1/2" x 2 1/2"
Hoping someone can help steer me in the right direction.
