Dorkfish ... Anyone Near KY .... I need help with Material ID.

I have these black nodules that I found for flintknapping, but I can't determine whether or not they are KY hornstone or Sonora. They were found with the the other saucer shaped nodules in the second pic which are definitely KY Hornstone. Any opinions?

Is there such a thing as Black KY Hornstone?
