Unusual rock

Asked May 26, 2018, 1:36 PM EDT

I have a rock that is about the size of s volley ball. It is light maroon and dark grey. The markings on it almost look like rose petals. I haven't seen one like it before and was wondering what kind of rock it was?

Thank you for submitting a question to Ask and Expert. I have asked one faculty member here at Michigan State and their first impression is that it is a conglomerate rock however, there is another faculty member that we are hoping will verify this answer and we are waiting for their response.

Thank you!
