One of my local spots to fossil hunt has a lot of limestone (I think) with what looks like worms running through it. I see this stuff everywhere and have no idea what it is. The area is definitely Glenshaw Formation and has fossiliferous limestone and shale. Any help is appreciated.

These pieces of "red" rock (I don't know the geologic terminology yet, sorry), have some unique features. Hopefully someone can help identify one, two, more, or all of them for me, if they are anything. If they are nothing, I'd like to know that also. These came from Jacksonville, Texas (south of Tyler, TX) in east Texas. Thanks in advance. 1) Is this an orthoceras nautiloid? 2) What is this impression? Ammonite? 3) Worm tube? Anything? 4) Worm tube? Rudist? Anything? 5) ?? No idea. Anything? What are the brown lines? 6) What is the "K" impression? Anything? 7) What is this impression? Anything? 8) Anything? Rudist? Plant? Or just wonderful coloring? 9) What is the yellow? Anything? 10) What about this yellowing? Anything? Or is it the brown lines? 11) Last one. Anything at all? Or nothing? Thanks

Here is (hopefully) one last post to help me identify some items I found while searching through the micro matrix from a Gainesville creek that Ken @digit was nice enough take us to. Some other items have been covered in previous posts:; http://www.thefossilforum.com/index.php?/topic/119097-gainesville-shark-teeth-question/&tab=comments#comment-1305867 http://www.thefossilforum.com/index.php?/topic/114209-north-florida-fun/&tab=comments#comment-1264293 The matrix comes from a creek in Gainesville, Florida and most of the fossils are from the Miocene aged Hawthorn Formation although there is occasional younger material. The fossil fauna is dominated by shark and ray teeth but there are lots of other items including: bivalves, gastropods, crab claws, fish parts, etc. (i.e. marine). What I have below are several items that I am uncertain about and hopefully someone can confirm my suspicion or give me a better idea. Thanks in advance for all your help. Item #1 is what I assume is a fish scale. Is that correct and can it be ID'd any more specifically? Item #2 is are two very tiny beautiful ray tooth. They look different from most of the Dasyatis and Rhynchobatus that I found with a much wider root. That had me thinking Rhinobatus but I'm not really seeing the uvula that I should expect so I could be way off. Any thoughts? Item #3 are a group of fish vertebrae. The two bottom rows are two views of the same 6 vertebrae and I have no doubt they are fish. It is the one on the top that I am uncertain about as it has a totally different shape. But I'm not that familiar with all the different permutations of fish vertebrae, so it may just be a different one. It reminds me of a mammal atlas, but maybe fish atlas bones look like that too. Item #4 are some items that I really have no idea. They look like little sacs and some are broken so that one can see sediment on the interior. While there is variability, most of them have a distinctive teardrop shape. Item #5 I am guessing may be burrow casts, but I'm not sure. Do they look familiar to anyone? Item #6 also look like casts of something, I'm just not sure what. They are generally very straight sections of a smooth tube form. All of the mollusk remains I have found are internal casts so no shell material is generally preserved in this deposit. Item #7 are, I don't know. My Paleozoic brain wants to call them eroded horn corals but I obviously know that is not right. Don't have another option in mind. And lastly, item #8 are probably worm tubes, just looking to see if that is right. They also have a common shape of being U-shaped or looped. They are not attached to a shell or anything (except maybe some matrix) like I am used to seeing with worm tubes. So that is my collection of oddities. I'd appreciate any thoughts folk have. Thanks Mike

This might be as interesting as it gets as far as worm tubes, so my question is if they are just tube casts why don't they all look the same? I have only found ones that are usually all greyish and look the same, these almost look like actual worms. Would different species have different tubes?

My daughter and I took advantage of the unseasonably warm temperatures over Christmas to go rockhounding at a nearby beach. She found what looks like a colonial corals. At first I thought they might be rugose, but they're smooth, not wrinkled and each corallite has this round "cap" on. So then I thought of syringopora, but I think for that the corallites are too large. Also, the individual corals grow/point into all different directions. That made me think that they might not have grown together, but were just deposited into a heap. What do you all think? detail of the area just below the darkish top: small vug on top of one of the corals, with a bit of the structure showing:

These are obviously fossils (from Tooele County Ut) but what on Earth are they and how were these formed? My best guess, worm tubes of some kind. I'm an environmental scientist (not a paleontologist or geologist) so making a positive ID is challenging. I've collected rocks & minerals for years and along with whats in my yard I've been trying to post the ones I've collected over the years that have fossilized characteristics. These ones certainly fit the bill and I seem to have 6-7 of these rocks. These also have florescent elements when I place them under UV light, with florescent blues, greens, orange and even some yellows. The rocks are covered in florescent lichens & cliches. The soil where I live is rich in colorful cliche deposits and lichen cover many of the rocks since I live near the benches of Tooele around 5,350 feet.

I found this fossil along Eisenhower State Park's hiking trails. This is close to Denison, TX in Grayson County. Right now this is the only photo I have, and it's taken from my phone. If it's not enough for an ID let me know, and I can hike back out for better pictures and more accurate measurement. It's roughly a square foot big. The different cretaceous formations found in our park are: Kiamichi, Goodland, Duck Creek, and possibly Antlers. I'm not an expert in fossils, but they are popular here, so as the park's naturalist I've been trying to learn as much as possible on my own using guide books and the internet. I appreciate any help!
