Possible whale ear bone?

[Nedhawks]

Found these on a one square mile earth moving project. Haven't seen any other rock like these types out there. I have found 3 points and a scraper pit there. I was wondering if anyone could determine if the top one is possibly a whale ear bone. The other may possibly be fossilized root or antler. Idk.
