    It's very pretty whatever it is..

    Picked from mix of QT, QAL, and Eagle Ford gravels. I love calcite but it can be deceiving, not sure if this was replacement of something or naturally formed structure, appears to be fossilized something. Curious about the red, mineral staining maybe? Last pic is view from above.

    Please identify this ammonite?

    I have no knowledge of this ammonite’s history. Does anyone have any idea of its type? It’s about 5 to 6 inches in diameter, a portion of it being fossilized with calcite.
  3. Went to creek I frequent but went down to a part I haven't been to for awhile, had several good floods since. Much to my surprise I rounded a corner and the bottom of the creek was pale yellow as far as I could see down. As you see in the picture there was shapes carved out by water, and it was very thick in places, but it was soft enough to break of pieces and it was grey underneath. So is this a layer of shale? If so why is it yellow? This may be natural in Eagle Ford and I've just never seen it in this form, just looking around I spotted this ammonite and just plucked it out. So now wonder

    Calcite shell?

    Hello everyone! I haven't posted here in a long while, mostly due to lack of finds. I dug this out of my collection, and wondered what it could be. It looked like some form of calcite, but has an oddly organic shape. I also noticed that it has some small fossils, possibly shells, attached to the bottom. It came from Al Ain, United Arab Emirates, near the foot of Jebel Hafeet. I am not sure of the age, but I assume it is Miocene. I have found many numulites close to the location, as well as gastropod steinkerns, and urchins.
  5. It was late, my back against an old brick building. Light rain comin down. Felt a bit cold. Pulled up the coller on my trench coat. Wondering how long ive been standing here. I realize there is a glare on the street from the lamp post. I pull the brim of my hat down. Then I see her. I tell myself to stay calm,,,, keep cool. I take the last drag off my ciggerett and flip the butt onto the street. The orange glow snuffed out immediately. I study her from underneath my hat brim. I can tell she has been worked on before. I don't move. I keep studying her. I can tell that she

    Advanced Dinosaur Egg Guide

    The Advanced Dinosaur Egg Guide Please share this with those who have egg questions. When possible, technical terms were avoided or defined. Every effort has been made to ensure accuracy, but it is always important to do your own research. This guide is merely a snapshot of information taken from many scientific publications. I am not an expert on eggs, rather I just love sharing what little I have learned over the years, what science has learned over the years. For an overview on how to spot a fossilized dinosaur egg and the sizes of eggs, see the basic guide:
  7. Found this in same creek by DFW airport, Eagle Ford/Alluvium mix. So has basic shape of an ammonite but really thrown off by strange pattern, not typical wear and each side so different. Just don't know what to make of it.
  8. Parkinsonia parkinsoni (ammonite) Jurassic, Upper inferior Oolite Bridport Dorset. UK 6.5" The first photos I took a few years ago did nothing for this unique specimen. I found it difficult capturing the details and still think they could be better. The ammonite has many chambers preserved in calcite that glow when backlit. Calcite crystals can be seen growing inside some of the empty chambers. Fossil, mineral, crystals, art, science, love Happy collecting.
  9. Hello, I found this interesting looking specimen in Port Charlotte, Fl. It is 2 inches (50.8 mm) long and 1.25 inches (31.75 mm) wide. It has teeny tiny honey colored calcite crystals in the segments and in the crack in the one end. I can see the crystals with a flashlight. I have many shrimp burrow casts but none of them are segmented, this is what it reminds me of though. Thanks for looking. Marie
  10. What is the best way to remove a fossil from Limestone? Thanks Greg
  11. I have some matrix pieces from ruck’s pit in Florida with some awesome calcite replacements And formations in the shells. I am open to all kinds of offers, including looking for other kinds of Matrix pieces, fossil fish and much more!
  12. Hello again, This is an interesting find found at the causeway in Tampa Bay, Florida last year. Looks like calcite covered coral or a sand fused fulgurite which I'd prefer to add to my collection, lol. What do you guys think? Thanks!

    Florida Fish Fossils

    Here are some of the fish fossils I have found, the first picture are some bones that I was hesitant to call fossils at first because they where scattered on top of a pile, but after find several other clay pockets ful of these I feel pretty good about them being gar fossils. Can anyone confirm, the internet is not being super helpful on this one? The next two are encased in a calcite geode i picked up while picking through the overburden, I didn't even see the imprints until i had washed it at home. Any ideas of what they are? From what i can barely tell, there are more in the g

    What type of calcite

    I found these in a large pile of dirt in a new housing development in Venice FL. I'm assuming they are calcite, but was wondering what type and what they are growing, incapacitated in. I found a lot of them and attaching 3 examples. They are holding yellow and growing on a charcoal, bulbuls rock. Thanks

    East central Florida

    Im still new at fossil hunting. Been looking at a few rivers small creeks here in Volusia county. I have also been searching the web. Still nothing comes up with hunting fossils and minerals in east central Florida. Volusia, Seminole, Brevard, Orange counties. You would think the st johns river areas would be a good place to search. If you guys know of any information that would be great?

    Cretaceous nacre

    Here Stolarski J (2018) From pristine aragonite to blocky calcite: Exceptional preservation and diagenesis of cephalopod nacre in porous Cretaceous limestones. PLoS ONE 13(12): e0208598. https:// doi.org/10.1371/journal.pone.0208598
  17. I just added this wonderful specimen to my collection. The species is discosauriscus. Little is known about the species other than the fact that they were predators based off of teeth. They may of had electrospective organs. On this slab running through the head of the specimen is a thick calcite seam from where the rock was faulted and shifted. This was found in the Czech Rebublic in the Limnic Deposits. This is the first fossil I've purchased all the others in my collection I have found.

    Calcite in the Peace river

    So i have heard stories of people finding crystals in shells on the peace river. I'm assuming it's yellow calcite but i could be wrong. Anyone hear the same or know some places?

    Scaphites in N. Alberta

    I was playing around in the garage tonight and thought to clean up a piece of scaphites that I'd picked up last fall in a ravine leading to the Smoky River in Northern Alberta. Three of us had worked our way down some pretty rough bush and eventually made our way into a mucky draw. The slope above continues to slump and it's not an easy time finding a place to pick around. One of the lumps I found was a crushed piece of shale 'glued' together by calcite crystals and holding a broken piece of scaphites. It's a fragile piece and it wouldn't take much to break it all apart but I carefully exposed
  20. Hi all, I've been searching the internet pretty thoroughly the last few weeks, checking everywhere multiple times a day to find a low-quality keichousaurus to practice prepping on, (knowing that 95% of specimens are fabricated or heavily restored) and I think I may have found one. The price is so reasonable that I really don't care whether or not it's partially fake or restored, as it will make a decent display or even a gift if it turns out to be 100% fabricated. So I suppose I'm wondering how much of this specimen looks fabricated, and if it would even be possible to attempt an air abra
  21. This post isn't so much about the fossils, but about me honoring the memory of Joe Gallo. It was the day I went out to do that in my own way and say goodbye and find closure for myself. So, if you're all about the fossils you may want to move on to another post. Two weeks ago Saturday I was on call. I had planned to go poking around at a Pleistocene area I had seen the day before NE of where I lived, but I got called into work to work on a kidney transplant. I worked from 9:30 AM to 3:00 PM. By then it was too late to go to the Pleistocene area since it was over an hour away from w

    Calcite ammonite prep

    I found this lovely calcite ammonite at Saltwick Bay along the Yorkshire coast of the UK a while back. There was no shell remaining from what I can tell, leaving just the calcite formed inside. Not sure if this is common at all?

    Not a fossil.. what is it?

    Hi all, Would anyone be so kind to enlighten me as to what this is? I'm pretty sure I've ruled out any kind of coral. The outside appears to be calcite but I just can't work out the sponge-like looking formation inside. The location was Tor Bay, on a bay just north of Saltern Cove in-between Goodrington and Broadsands Beach. Mudstone and Limestone - Devonian. Any help would be greatly appreciated.
