Definite similarities Randy! beefjello - Do you know what your plans are for yours? I have an idea what I'm going to do with mine - possibly a lightbox, but I'm still trying to figure out some of the logistics.

I’d say there’s a good chance the owners of those two splats shared a very similar diet!

When you say lightbox are you referring to the night lights that Randy and others have posted or something else? My mind immediately went to a wood box or frame holding the slab with a light inside, and my mind liked what it was envisioning.

TURD TUESDAY I love the dancer in that one! It’s amazing to see the different patterns in these rocks. And also to think that if you had cut from a different direction, the image could change completely.

It really needs a high lumen light behind it, so I don't know yet how I'm going to achieve that. I was thinking like a frosted plexi-glass front with the shape of the slab cut out. I'd bevel the edge of the hole in the plexi-glass so the slab would fit snugly into the hole and be held in place. Edit - I see the dancer in that slab too!

The only problem I can think of is the heat build up in the box. A few vent holes top and bottom should help that. There are a couple alternatives for the front. First, you could square the edges of the slab to reduce the complexity of the shape. Second, you could simply cut a piece of wood rather than plexiglass to hold and frame the slab. My concern with the plexiglass is that it may be more translucent than your slab, making the slab have a glowing halo that would make it more difficult to see the patterns in the slab. That is assuming I am envisioning your design properly, which I may not be.

That is assuming I am envisioning your design properly, which I may not be. You are envisioning it exactly. You're dead-on with the plexi-glass. It would take away from the illumination of the slab. So I'd need to make that non-opaque. I don't really want to lose the complexity of the slab. I think that adds to it. If I traced the shape, routed the general shape so there's a "lip" to keep it in the opening, it could be held in place on that lip with an epoxy or glue of some kind...I would think cyanoacrylate would work, depending on the heat from the light source...

Use LED lights.

Use LED lights. I was kind of figuring LED was going to need to be the direction. I'll be looking into trying to get this battery operated, rather than plug in. I'll have to search out the components at some point. Tons on my plate right now...this is on the "to-do" list! I'm going to try and get this done before Randy whips out that sauna though! LOL

A recent study just called into question the presence of rocks in the digestive system of prehistoric birds. What were originally assumed to be gastroliths are now believed to be chalcedony formed during the fossilization process. Link to article. It would be interesting if dinosaurs used gastroliths while their contemporary feathered friends did not.

I browsed a little bit and was intrigued by the mention of a rain shadow that affected the paleo climate East of the Sevier orogeny. All very interesting especially for those folks who are familiar with this area.

I think peat layers are entirely feasible from what I've seen in that area 1daveI've found numerous layers in the Morrison formation of the region where it's obvious there were vast deposits of organic material. The area southwest of Hanksville where jet is found is an excellent example of this.

In my quest to label and categorize my rough fossils/rocks, have also been pairing some together with notes for future plans. My idea is to pair coprolite with dino bone. Would be for pendants and bracelets. Has anyone done this before? If so, would love to see photos.
My logic is why not? Pair the bone of a dino and its' poo. LOL.

I'll try to get some photos from him.

Those turned out great, Jason! The first one really seems to have a lot going on. It doesn't even look like it should have stayed in one piece. I hope your father-in-law loves it!
