Some Weekend Finds

Here's a few specimens I found this weekend.

The first few are from the location in my previous post where the coal seam and ancient beach are located.

The first pic is a rather poorly preserved Lepidodendron tree bark section:

ol.site9.lepidodendron.jpg


It's significant to me because it's the first Lepidodendron specimen I've found in this region.

The second pic is what I believe may be a section of a Calamite trunk:

ol.site9.calamite.jpg


Both are plants from the Carboniferous and make sense considering the coal seam.

The next pics are from "site 10" in the same area.

The first is a first for me in this area -- a perfectly-formed gastropod with spire intact:

ol.site10.gastropod1.jpg


Next is the largest ammonite I've found in this region.

I'll be working a while to get these freed from their matrix. I'm also anxious to put these specimens into their geological context of the area (below or above the coal seam). So far, I'm pretty sure they are below the coal seam.

Last is a spectacular Echinoconchus semipunctatus specimen:

ol.site10.echinoconchus_semipunctatus.jpg


This baby is HUGE (83mm X 83mm) and according to the books as large as it gets.? The largest one I've found to date is a meer 65mm x 65mm.? I'm going to have to work a while to get this one out of the boulder it's stuck in.? It's also intact with complete (if fractured) brachial valve.

I think that last brach would be hard to perserve intact.
Your home must look like mine with a heck of a lot of rocks hanging around.

The second pic is what I believe may be a section of a Calamite trunk (UPDATE: This is most probably a bark impression of the lower portion of a Sigillaria tree rather than Calamite.):

I bought a full-size (15 lb) sledge hammer today. I'm going after that rock this weekend to see if I can break it up. If so, I can bring home a chunk with the brach in it and get the air-scribe after it.

I also spotted an ENORMOUS spiriferid on edge (posterior view) in another small boulder. Going after that one too this weekend. I'll let you know if I'm successful.
