  1. Hello everyone! Firstly, I know that this is a topic about whether or not a fossil is real, but seeing as a), I'm not looking to purchase one and b), I'm mostly interested in how they could possibly form, I've put it in the general fossil discussion. If an administrator thinks this topic would be better for the 'is it real?' discussion, please feel free to move it. Anyways, a while ago the above Captorhinus fossil was posted to the 'is it real?' discussion board, which I thought was an obvious fake, as the matrix looked unnatural, the cervical ribs looked less like ribs and more like sea urchin spines, the skull was miraculously immaculately preserved and the knee joints were facing in the wrong direction for tetrapods. However, I was browsing the internet, when I came across the Wikipedia page for the Richard's Spur Quarry, and saw this image of Captorhinus aguti: Now, these specimens obviously look more real than the fake Captorhinus at the top; although I know Wikipedia isn't always a reliable source the information on it is usually not too far from the truth, and I'd be very surprised if they had fake fossils as images representing 'real' ones. However, I still have my doubts about these two skeleton's legitimacy; the skulls looks too well preserved and a bit like resin, and the knee joints are yet again facing the wrong direction. Are these fossils real, and if so, how did the skull preserve so immaculately while the legs were distorted? Is this something unique to Richard's Spur? Thank you for your help.
  2. I have had this question for some time now and recently had it come up again. I was wondering does anyone know if there are particular conditions that affect the number of Conservat Lagerstätten we see on the earth at any given time? I got this question because in my time collecting and learning about fossils it seemed to me that times like the Cambrian seem to have quite a number of these sites, and the type of preservation in them seems fairly consistent and similar, as we go into the Ordovician I know if fewer but still a few and they also have pretty similar preservation. The Silurian and Devonian on the other hand, seem to have much fewer, off the top of my head I can probably only think of a couple, but then you get into the Carboniferous and it once again seems like there are much higher numbers of these sites. The Carboniferous is especially interesting because a number of these sites have more usual nice preservation like Bear Gulch, Kinney Quarry, Hamilton Kansas, etc but also a number of sites have Siderite concretions with exceptional preservation like a few sites in the US including Mazon Creek and some in the UK I believe, a type of preservation I have not seen in any other time periods. I am not sure if this patchy record of sites with good quality preservation continues further outside of the Paleozoic, but this is where I noticed it occuring due to mostly focusing on that time span. Is all of this down to the different conditions on earth during these different times? Is there a degree that our sampling bias or just how much attention each of these gets that plays into how many we know from each time? I have been curious about this for some time and thought maybe someone here would know more about the subject. Thanks for looking! Misha
  3. Tales From the Shale

    Preserving Invertebrate Fossils

    Hey guys I have some fossils I collected from the Coon Creek of Tennessee. The resident paleontologist, and other trip goers told me to use floor wax to seal these delicate fossils. They aren't permineralized and therefore crumble and crack very easily. Is there a better alternative to floorwax? I read both yes and nos on its usage. I don't like modifying fossils if I don't have to, but I've had multiple fall apart already.
  4. Hi all I found a fossilized bovine tooth while creek walking several months back. While it seemed stable at first, it now has begun to develop some fine cracks in the mineralized enamel, and one small flake has already come off. I was hoping to learn the optimal way to stabilize a fossil like this. What would you all treat it with? I attached a photo if it helps. Thanks!
  5. I an putting together some hand-outs for the Dallas Paleontological Society table to use at local events. We are committed to educating the public about the science of paleontology. Below is one proposed list that I have put together from different sources and re-worded to fit in a small space. Some of you may find mistakes or other things to add or even a better way to explain something. I would appreciate any help you can offer. Anyone should feel free to use this in any way you like. Any other material you think would make a good hand out would be appreciated. We have a nice deep time chart and a hand-out on age-dating fossils as well as diagrams of local strata. Thanks. 20 WAYS FOSSILS CAN BE FORMED DUPLICATION 1 Internal Mold (sediment in contact with inner surface solidifies then original dissolves) 2 External Mold (sediment in contact with outer surface solidifies then original dissolves) 3 External Cast (original outer surface dissolves and space fills with solidifying material) 4 Internal Cast (original inner surface dissolves and space fills with solidifying material) MINERALIZATION 5 Permineralization (space between cells fills with minerals that solidify) 6 Petrification (space between cells fills with silica binding to cellulose) 7 Repalcement (cells replaced with new minerals that solidify) 8 Recrystallizaion (replacement when the new minerals are a crystal form) TRACE FOSSIL 9 Tracks 10 Infilled Burrows 11 Coprolites (animal droppings) 12 Feeding Traces 13 Urolite (urine splatters) 14 Regurgitants (animal vomit) DESSICATION 15 Peat Pit 16 Tar Pit 17 Frozen Tundra OTHERS 18 Compression (thin carbon film formed by chemical change under pressure) 19 Resin Inclusion (Life trapped in resin which hardens into amber or copal) 20 Bioimmuration (impression formed on a shell by growing over another life form)
  6. Hello, I was wondering if any kind of sealant was required to preserve shale fossils from Arkona?
