Paleontica Community

Hello everyone,
I am from Germany and recently visited Maasvlakte 2 for the first time.
I found this specimen on the beach near parking area P2-3


I wonder if this is fossil bone, fossil wood or something else.
Any help would be greatly appreciated.
Thank you!

Rene

I see several pieces, some rocks, some wood and some bones. The second last picture is a beaver femur.
