I took another trip to the creek by my house today since the water had finally gone down. I found a few fossils, some that I could easily identify as Artisia (one of the most-common fossils here), but there were a couple other oddities as well that may or may not be fossils (though I'm not going to be posting most of them). This was the main thing that caught my eye: I know this area isn't a "true marine deposit," but this thing's resemblance to some polished ammonite fossils that my dad got me last Christmas is uncanny. Is it actually an ammonite (or related species) or just a suggestive rock? I also found a tube/pipe-shaped rock during my hunt. I'm not sure if it was an oblong nodule that broke off on each end, some heavily-weathered Calamites/Coradaites (or other hollow tree-like plant), bone, or what. Unfortunately, I couldn't get my camera to focus on it just right (my batteries were going dead). If any of you can tell what it is from these blurry photos, however, please let me know what you think!

A bit late, but here are the finfs from my Christmas Day trip to the North Sulphur River. To start off, a couple of small cephalopod bits out of the Ozan "red zone." Next, a chunk of ammonite. The coloration on this one isn't what I'm used to from Sulphur cephalopods, and some chips in the surface revealed that under the outer coating, a lot of crystalline minerals were present. Here's a digital microscope image of one of the chipped areas, showing the mineral crystals. Continued in next reply...

I bought this fossil at the Nature's Gallery in Carrollton. Not sure if it's an ammonite or a nautilus. Also can somebody tell me the difference between the two and how to distinguish them? sorry for bad quality.

Got this at Bearreraig bay on the Isle of skye a few years ago and have always just assumed the ammonites are all the same species and Ludwigia murchisonae but decided to seek some clarification on this, any help would be much appreciated (the biggest ammonite is 10.5cm)
