Brought back a stone with a fault line on it from the shore of southern Lake Huron.  Broke it open with a chisel and hammer to reveal an ultra thin shell like fossil.  I wonder if someone can help me identify it.

Hm. Is it possible to show more and clear views of the "shell"? To me it looks like a sand dollar fossil based on the lumps in the center that resemble a star. Another possibility could be a thin enchinoid surface, if thats possible. 

If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Looks like a Rhipodomella sp. brachiopod, to me.

Rockwood gets extra dessert for guessing the size based on the wood grain.  I love that.

That is brilliant, Rockwood is definitely the Sherlock Homes of the fossils world but I do suppose it was just elementary.

That was my initial thought, however, if you look closely at the mold, it lacks a straight hinge line.

The more rounded shape is more consistent with Rhipodomella, or some related orthid  brachiopod.

maybe he could tell us the age of the oak tree as well

I'd like to meet the person who could do that from this aspect myself.

First lesson; that's not an oak tree with the tumbleweed passing by :)

Feel free to point out what an ash I'm being if I misinterpreted.

I was wondering does his eye for detail and ability to work out the size of a fossil from oak grain be a transferable skill to say  for example. can he tell the size of a fossil placed  onto a billy bookcase from Ikea.

I have learnt at lot from from Rockwood on this forum indeed.

Furniture, smart phone, I wouldn't have known the difference.

My father is dyslexic and a member of a masonic organization which runs schools that do amazing things to help those with the condition. 

Just thought you should know it is possible.

Thanks Rockwood for the information. You never know I will look in to that.
