Coral at Blankenbaker Road?

Some type of coral or bryozoan from the road cut at Blankenbaker Road in Louisville. I stopped there and looked for about 30 minutes and found not a lot of signs of fossils. An occasional crinoid stem disc embedded in the rock.

Lots of little bubble like shapes in sheets on the rock at different layers. Some sort of pseudofossil? A later post will show what I am talking about.

Blue Geode

Okay, this is not a fossil from the Louisville area but a geode from an area around Lake Cumberland, Kentucky. It was blue colored so I took the diamond saw and cut it in two pieces. It was almost solid but not quite.

I might try and polish it to see if brings out any details.

Crinoid Holdfast

Here is a neat crinoid stem that my cousin found while at Lake Cumberland, Kentucky. It is a Mississippian period crinoid stem with a smaller one attached to its side. You can see the hold fast with its root like appearance holding onto the larger stem. A smaller stem then makes its way up to produce another crinoid.

It appears that the larger stem was still alive when this happened or at least its bottom portion was still standing when the smaller crinoid attached and started to grow.

The bottom picture shows both crinoids on their side and taken from the opposite side from the first picture.
