Is this really petrified dino dung?

Going through my old rock collection from when i was young.  My grandmother gave me this and told me it was petrified dino poop.  Is that true?  If not, what is it?

    The whitish part with reddish veins looks like quartz.

    The darker part is hard to tell, could be almost any rock.

    Does not look like it. You can google coprolite and see if what you have matches what you will see. Feces is made up of a pile of small particles of undigested food and is more like sandstone. Yours looks like a chunk of solid rock.
