Is this a shell?

[Aimblv]

This powdery stuff gets all over your hands I have soaked these Many times but that stuff is all over it

Also , I am From east tx but not entirely sure if they were found here but more than likely from tx I'm guessing

 

[dirtydig]

id say yes and if its fossilzed the the white stuff is probably calcium

 

[Aimblv]

Thanks dirtydig I have a question is there a way I could get the calcium off the shell or maybe clean it up without messing it up ? I have several of these

 

[Harry Pristis]

Can't think of a good reason for the oyster shells to be shedding. If they are calcium carbonate, maybe moisture in the air is reacting to form carbonic acid so that the shell is decomposing. Stop it by sealing the shells with a consolidant. Try Duco Cement (clear model cement) diluted with acetone.
