Almost looks like a STYLOPHORA . It doesn't look dead. It looks like it is just lacking color some do to photography and some other things. It would help if you can get some cleaner pictures. I do see he polyps outlay over it.
Did it come from the bottom of a bigger colony if so that could be because lack of light.
I may be interest in the coral but would like to get a better look at it. Unfortunately I live in Florida and can't just stop by. Do you have any other camera options. My galaxy phone takes pretty decent pictures. Also try turning up the whites to get a better picture.
