Fossil formation is rare, so a fossil capturing a rare behavior is pretty darn unlikely. A behavior would have to be ellicted many, many times to have a likely chance of being preserved in a fossil. Surely they exist, and this could be one of them, but until we find evidence to the contrary our best guess should be that this was a common behavior.
