Strange coral found on Wisconsin beach

Recommended Posts

I was at Doctor’s Park beach in Milwaukee County, Wisconsin today. It is a known Silurian reef outcrop and I found much of the usual plus this weird piece of coral. I have never seen coral like this at this beach and I’ve been going here periodically for months. I attached a side, top, and bottom photo. I wanted to wait until I finished my trip to show my entire haul, but I am really curious about this thing. I almost mistook it for a nut that fell into the lake, but it’s definitely rock.

Definitely a worn solitary rugose coral.

Yup, and very common on Great Lakes beaches.

Fossil hunting is easy -- they don't run away when you shoot at them!

Unless you are Illinois. Never found anything on an Illinois Lake Michigan beach.

Lately, no -- it's been picked clean. Back in the 50's and 60's there was lots of material before they started "grooming" the beaches. Most of the sand on Illinois beaches is imported.

Importing sand: what a wonder use of taxpayer dollars/sarc
