Three bone like 'fossils' found together, any idea what they may be?

Hello,

 

I recently found these three items in Custer County Oklahoma where Quaternary mixed with Permian and Cretaceous bedrock can be found. They were all found about 5 feet from each other with items one and two on top of each other. When I hold them they remind me of a terracotta pot in texture and kind of sound like terracotta when you tap on them. I am guessing they are fossilized bone? If it is bone I would love to figure out what it came from but understand that determining exactly what it was from may be difficult.

 

I appreciate any input on what they could be and would also understand if its too difficult to determine.

 

 

Below is item one, kind of flat.. Maybe a Skull?

Item 2.. Looks kind of like a rib or Leg bone?

They do look like fossilized bone. You are correct that a further identification will be difficult also. The only suggestion I might add is that the look of the first one is something like would be expected in a vertebra as well.

Thank you! I guess I will keep it out of the rock garden at least.
