Lexington Lm

[Guest solius symbiosus]

I stopped at a location a thousand or so meters down the road from where I have been collecting lately, and found some of the largest "heads" of the tabulate coral Tetradium I have ever seen.

As it was getting dark, and my car was a ways down the road, so, I didn't bring anything back but a few small pieces of the coral. I did pick up a couple of cephalopods, a cranidium from a Gravicalymene( The first trace that I have found of a trilobite since picking up the hobby again), a few brachs., and a solenopora sponge.

Anyway, check out the size of these things:

There was a bed that was full of these things, but really, they are to large for me to do anything with ... maybe set out on the back porch?

Here is the outcrop.

It is the Millersburg mb. of the Lexington lm.

The Millersburg is a nodular shaly limestone that was deposited in a shallow environment. It is overlaid, disconformitably, by the Tanglewood mb. which is a coarse grained calcarenite. The Tanglewood was a beach deposit.

The bed that is visible in the upper left of the photo, is the Tanglewood mb.

Those are of mammoth size. If you have a garden, you could place then around a plant as a border. Think

that would look pretty cool.
