I found this in my backyard in Massachusetts when I was playing in the dirt 25 years ago. Can anyone identify what it could be? Is it a dinosaur poop? Egg?

Doesn't look like coprolite to me (dino-poop) or an egg.
I'd swing more toward the bone or tooth theory.

Any chance of a clearer close up of the interior, or perhaps you could describe it for us.
Does it have a perforated structure internally or a more crystalline composition?
I reject your reality and substitute my own...

Concretion ? (they can form around a fossil, but do not necessarily have one inside ).

Probably my first choice. Otherwise, there is not enough info (or clear eough picture) to make an educated.

I think egg can definitely be ruled out given the size of the find and the thickness of the "shell" :
a chick-sized hypothetical baby dinosaur is going to have difficulty making its way through a 5-10mm thick shell.
