  2. Coral Identification

    Last Thursday, I visited the Langhian Weißenegg-formation about 30 km south of Graz. I have only checked out areas north of Heimschuh in the Sausal hills this day, that I have prospected already four years ago for coral specimens. The Weißenegg-formation is mostly limestone, containing in some parts coral carpets and patch reefs, witness of the subtropical to tropical climate in this area about 15 Million years ago. Fossils in the "wild" (aka forests) are not super-abundant in this formation, with corals being the most common, but there is a very large, active quarry for portland cement fabrication in Retznei nearby, that is famous for all kind of marine stuff, incl. Meg teeth and other large vertebrates. But as some of you may know, I am not interested in active quarries . (Note: The quarry operators are very cooperative and supportive saving fossils encountered during mining, and fossil collectors are welcome!) Quite a distance below a small limestone cliff in a forest north of Heimschuh, this coral specimen was presenting itself on the soil below an overturned tree. Its shape is essentially that of a half-cone (pic middle left, above red object, specimen as found, untouched). It is a chunk of a coral colony that is very nicely weathered all around, with absolutely no ding. Skeletal elements are more strongly weathered than the infilling sediment, so the specimen is essentially a negative. I have tried the usual method inverting the greyscale pic, see lower left. Preservation is very good, I think it is a Montastraea sp., considering the size of the corallites, strong costae and spongy columella. Such nicely weathered specimens are very rare, its only the second one that nice that I have found in this area. Any thoughts as to if this is a Montastraea? Franz Bernhard
  3. Chicxulub impact acidified the ocean instantly

    After all. How may huge impacts have there been but with no huge fossil beds around them? Not talking worldwide in these cases but as local.
  4. Chicxulub impact acidified the ocean instantly

    Yes. But what if the impact while major wasn’t the disaster invisioned. IE what if many of the creatures alive then survived the impact but the environment effects are what caused the biodiversity explosion that occurred afterwards. There are theory’s that believe that great environmental stresses speed up the evolution of species as “Mother Nature” tries out new models to cope with said stresses. Just speaking hypothetically of course. theres a whole stretch of time where there were no large animals and we all know how few small mammals and stuff get fossilized..
  5. New Mazon Creek Collection

    Terrific collection! I love cracking open nodules. It's highly addictive. Two must haves if you're into mazon creek or just love the Carboniferous. The Mazon Creek Fossil Flora by jack wittry. And Richardson's guide to The Fossil Fauna of Mazon Creek. Charles w. Shabica and Andrew a. Hay editors. Wonderful books. What do you use to for pics? Nice close-ups.
  6. Ummmm odd!

    Water worn rock. Not a fossil.
  7. Found in coastal georgia miocene

    Broken whale tooth, I think.
  8. when does archaeology become paleontology?

    Dates like 30K for "anatomically modern" humans are a subjective prejudice imposed by western anthropologists. H.sapiens has been H. sapiens for a good long time as evidenced by finds from South and East Africa where evidence of art and culture suggest a fully modern brain. There is still much bias in the science today.
  9. Found in coastal georgia miocene

    Found this diving coastal georgia. Not sure what it is. 3.5" in length. 1/2" in diameter. Found in same location as whale verts, horse teeth, meg teeth, and great whites. Any help is appreciated.
  10. The 2019-2020 Fossil Season, Peace River Group Hunt Thread

    Sounds like a good idea! I would be interested in hunting the Zolfo Springs area. Having only started hunting fossils this year I have not had the opportunity to dig in Zolfo Springs. I am always ready for a new adventure and it would be great to meet some other Florida hunters.
  11. Hi gang, been awhile...I was puzzling over these two items below again. Found several years ago here in Florida. One a possible osteoderm? and the other an ungual? Mio/Pliocene? or Pleistocene? in age. First specimen I thought was some type of tortoise armor, has a concentric wafer shape and is about 3 cm across and about 1cm thick. Under closer inspection there appears to be an odd fracturing going along the outside and also some minor cracking which appears to be forming a hexagonal outline/pattern....Just a coincidence? Do any glyptothere osteoderms show an internal hexagonal pattern? Left photo is ventral? and the far right photo is the opposite side--dorsal view? Middle photo highlites the fracturing/cracking patterns.... 2nd specimen I thought was a tortoise ungual but in looking at several older threads I'm now wondering if it looks more like it might belong to a glyptothere? Its only about 2cm long. Thanks for any/all help. Regards, Chris

  13. Carboniferous Terrificous

    Mazon creek fossils. Preserved in ironstone concretions. 309 Mya. Mid- Pennsylvania epoch of the Carboniferous period. Enjoy!
  14. Carboniferous Terrificous

    Here are some fossils I found in the town of St.clair in Schuylkill county , Pennsylvania. Llewellyn formation. 300 Mya. preserved in black shale.
  15. Just an fyi, Chilean shark and some other material is still available online through several domestic dealers. So if you want any it's your safest bet. @Dracarys

  17. Hello to all! I have recently won the rolling auction here on the forum, and one of the items included was a Cambrian panlongia from China. I understand that the two species of Panlongia can be distinguished by the presence of spines along the sides of the thorax but I really can't tell on this piece, so if there is any other way to know which it is I would love to hear it! At the same time the same piece of matrix features something else right next to it, I am not sure what it is, could it be a brachiopod? And when flipped over there is another fossil looking object below it, is this some kind of ichnofossil or something else? Thank you very much, Misha
  18. Latest Scottish Carboniferous finds

    @t-tree @Ludwigia @connorp @nala @Monica @deutscheben Thanks everyone! This jellyfish is by far the clearest example I've found yet many are pretty hard to see and almost impossible to get a good photo of, I must have missed a good few over the years while my eyes were set to tooth mode! Prepped the crinoid earlier today as much as I can I think, there was more of the arms but they are pretty disarticulated. I'll post some pics tomorrow.
  19. Chicxulub impact acidified the ocean instantly

    Not all ash is the same. Most volcanic ash is mostly silicate, great stuff for preserving dead animals as fossils, especially a thick layer of it. Most ash from fires are metal carbonates and very alkaline, great for making soap from animal fats. Even if dinosaurs were gone before the impact, something should have been around to get killed and fossilized.
