I dug this rock up in my back yard today in Madison County, Alabama. I was not surprised to find the typical fenestellate bryozoan fossils that I normally find, but I am puzzled by a couple of things. I will post a some photos to show the bryozoan fossils on the rock and then macro photographs of the parts I have questions about. The pod like structures remind me of some that I found on another rock from TN, but with encrusting bryozoan fossils... The other "thing" looks like some type of stem? Are these structures of the bryozoan colonies? I see one crinoid fossil on here, too, but that stem didn't really look crinoid-ish to me? I have been known to be wrong (often), though... Thoughts and suggestions appreciated! Thanks!! Ramona

I am on a mission to determine if I have different types of fossils in the bottom of our creek bed than I do in the rocks in our yard. This is the first rock I have photographed and I saw a bryozoan fossil I didn't recognize! At least I think it is bryozoan... I have learned not to make assumptions... I recognize the fossils on the right of the photo as fenestellate bryozoans. The portion on the left is what I am not sure about - the honeycomb like part. It has some of the characteristics that I am used to finding in the fenestellate bryozoan fossil rocks, but it also reminds me of the trepostome bryozoan, since it has the appearance of being encrusted. I also read about Monticulipora bryozoa and lamellar cyclostome but I don't have the depth of knowledge to know the difference. And then there is coral? Honeycomb coral? Seems like this is too small? The small rock on top was part of the rock at first but it fell off when I was cleaning it. with a toothbrush and water. Also, as a bonus question - I get those, right?!! - what might the two types of lines on the side of the rock be? There is one type that is a single dashed line but the other one is a pair of dashed gray lines that separate and then come back together. There are quite a few of each of these on the rock - I can provide better photos if needed for identification. For those who have not been bored by my bryozoan posts yet, LOL, this rock was found in Huntsville, AL. Thanks!! Ramona

I had a chance to look for rocks in a new location today and WOO HOO, I found a huge rock that should keep me busy for a while! This baby is filled with tons of interesting things! I am going to start with just a couple of questions that I THINK I may know the answers to. Are these samples of a type of Fenestrate Bryozoan fossil? If not, maybe coral of some type? These were found at the base of a small mountain/hill in Pulaski, TN, where no fossil hunting has been done (yet!). If these are a type of Fenestrate Bryozoan, it looks like they have more of the structure intact than I am used to - thoughts on that? Thanks again! Ramona
