I have a coprolite from Sihedang Town, Chaoyang City, Liaoning Province, China. The preparation was bad, and the coprolite itself came free of the matrix during shipping. Since it was a good sacrificial piece, I decided to dig around. I found this tooth, but unfortunately, I broke it before I was able to extract it or get a microscopic image. Any guesses? The coprolite contains no scales, but there are fish bones and vertebrae partially exposed. Thanks in advance for any help you can offer.
