NSR Footprint? (2)

Ozan Fm. (red zone) clam impression

Thanks...I figured it wasn't a footprint since it was covered with water at the time, but it does kinda look like a bird footprint :-) My 8 year old son and 5 year old daughter have determined that it's a dinosaur footprint...and nothing is gonna change there mind on that :-)

Thanks for the help...I'm still new at this (since March) so I really appreciate any and all feedback.
