Answer
Hi Sharon,

It would help if you could be more specifc, and also if you could post a picture.  What species of turtles are these?  I'm also not sure what you mean by "shell like."  Was it a piece of eggshell, or something else?  If an egg was laid in the water, it's unlikely to be viable, so I don't think you need to worry about it hatching.  It might possibly have been something else, so if you can post back with a more specific description and information, I can be of more help.
