As we have some top fossil experts in the house as of late, I'm hoping to get an ID on a couple things I've picked up over the years. First is something I found as a kid near Lake Havasu City, AZ. It was in a big nodule I found in a wash and busted open with a hammer. This is the only piece that I can still account for back side Also this one I found several years later and several miles up the Colorado River near Laughlin I'm thinking coral? maybe? Thanks!

Nice fossils Brian. Im gonna take a guess and fossilman will be by later to tell you what they are. :-)
#1 is some sort of oyster #2 is a head of some kind perhaps a crinoid head or something similar.
We'll see how far off I am.

Brian, I'm not an expert at all but the second one looks to me like a hyppurite. That's a sort of shell with very unequal valves - one of the valves is like tube and the other one is like a lid. They have these stripes I can see on your fossil. Adrian PS. at a second look, the stripes are continouos between the "tube" and the "lid". Also there it a curvature between them. That makes me doubt about this being a hyppurite. I gave you a lot of help, did I?

I'm here finally. The first one looks very much like a fan bryozoan, or a coral. A Hippurite (rudistid) is a good guess but the stucture is a bit off, and the likely age is questionable. What's the age? Paleozoic=fan bryozoan, Mesozoic, Cenozoic=coral.
The second one looks like a button coral. Without an age, it's a bit hard to tell. I don't see any plating so echinoderms are out. Is there a small attachment point on the base? If so, it's probably a coral.

Thanks for narrowing these down guys I have no idea what the age is on them. I'm sure with a little research on the areas they came from an approximate age could be determined. The first one has a scallop looking clam thingie embedded in it. You can see the rib like impressions near the lower center. As far as attachment points on the second one I'm not sure, I'll try and get more pics posted of it at some point. Thanks again
