    I liked the uncluttered format of this pic,decided to post it
  2. dagrimaldiCretacTropiclLizard2016.pdf HIGHLY recommended*,for reasons that will become immediately obvious Less than 2,0 Mb *the why of it: 1)simple esthetics(extremely pleasing(I think)photographic coverage) 2)the style of preservation,with concurrent implications for,e.g.phylogeny) below:the least interesting illustration

    What a fitting tribute!!!!!!!! requiescat in pace,Ian (4,2 Mb) related:
  4. Petrified Wood?

    Not sure if this is petrified wood or a concretion due to the dark center on one side. I could use some clarification and input.
  5. Fossil or inorganic

    I've been told this could be something, fossil or inorganic. It was found in the same Mesozoic area as previous finds in the Big Sky, MT area. Just looking for some input pertaining to what it could be whether it's a rock or something more......
  6. Heteromorph, right side view

    From the album james herrmann

    In this right side view of the sculpture I would like to show the green marble base. I chose this mottled green marble as a continuation of the kelp forest theme. I envision this ammonite pulling its way along the waving fronts of a kelp forest as it forages for small crustaceans. Kelp forests are contrasts of warm, bright beams of light and deep shadow. The marble is mottled in various shades of green much like looking down onto the kelp forest's waving fronds.
  7. Heteromorph, front view

    From the album james herrmann

    In this view I again wanted to show the cantilevered structure of the sculpture and the subtle color differences in the patination of the shell vs the body of the ammonite.
  8. Heteromorphic Ammonite Left Front View

    From the album james herrmann

    In this front left view I wanted to highlight the waving of the kelp. The challenge was to strongly support the heteromorph while still making the sculpture feel like there was movement and a lightness to the work.
  9. Heteromorphic Ammonite Left Side View

    From the album james herrmann

    This left side view of the sculpture shows the attachment of the ammonite to the kelp, actually there is a lot of bronze in the mass of tentacles. From the base to the top of the sculpture is approximately 40 inches.
  10. Heteromorph Sculpture Left Rear View

    From the album james herrmann

    I like the complex repeating nature of the spines in this view of the sculpture. I am supporting the mass of the bronze ammonite with the bronze kelp leaves welded into a trellis-like pattern to carry the weight down to the base.
  11. My New Heteromorph Sculpture

    From the album james herrmann

    Heteromorph is my most recent sculpture with a paleontological theme. This is the rear view of the sculpture showing the shell spines.
  12. possible femur bone

    The coin in the photos is a 50 cent piece. Found in Western Colorado. Really unsure of type. Piece is very dense, similar to river rock. The thickness of the bone at joint is 2 3/4".

    graversichnolmilanJOGfulltext (2).pdf climate,diagenesis,rheology,aetiology. Knowledge of at least some common Structural-geological terms with regards to faulting and folding is necessary to totally understand this. Recommended,with the reservation that not every ichnite on this planet is preserved in eolianite(arenite("sandstone)" lithologies
  16. Prognathodon Tooth from Morocco

    From the album My Fossils

    I found this tooth from Morocco I’m a shop in Portugal. While the root could be faked in someway. The actual tooth, is real. I did a post on this before but I took much clearer images for the ID for this later on. I decided to repost with these images.
  17. small dromaeosaurid,oldie but goodie

    xinxuxiaolsmallestdinosazhaoianusmicrorapnaturezhonghetopost200010b4c14c3.pdf the other paper on this species(Hwang/Norell) is ,naturally,in Fruitbat's Library,possibly in some others as well salient points(or:"things you might want to remember about this article")(apart from osteological details): edit,hours later:possible repost,because I just noticed this one in Fruitbat's Library. Joe,i feel i owe you an apology. note Maniraptora (GAUTHIER): I posted the Gauthier,a very influential cladistic paper,a while back Note 2: "Archaeoraptor" turned out to be forged
  18. Montego Bay

    Although fossil finding was not part of our vacation itinerary, fossils found us. After our boat docked outside of the strip just outside the town of Montego Bay, there was a large shelf of limestone filled with coral fossils. I had just been snorkelling in the living coral reef at Secrets Bay, and it was fabulous to see corals in living colour with all those abundant tropical fish eddying about. The limestone here dates between the Mesozoic and Cenozoic, and is largely dominated by coral. Some of the specimens in the rock have very nicely defined corallites. As I didn't think to bring a rock hammer on vacation, I did manage to find a loose rock to hack out a few small specimens. This first batch shows these corals in their raw, in situ context:
  19. Please help with ID of sponges, corals and bryozoans

    Dear Guys, I collected some interesting specimens in Jurassic- Early Cenozoic erratics like sponges, bryozoans and hexacorals and also two primitive Ordovician sponges. The sponge pieces are 3-8 mm length (In yellowish limestone on sponge has very interesting skeleton growth outside). The size of coral in greenish gray limestone is 9 mm diameter, in the white limestone- 7 mm diameter. The bryozoans are from 7 mm to 1 cm length, they web shaped. Please help with ID of these fossils if you could. Best Regards Domas 1. Late Jurassic sponges in my opinion. 2. Early Cretaceous (?) sponges. 3. Late Cretaceous- Paleocene sponges I think.
  20. I was in a local Barnes & Noble last week and was happily shocked to see that a second edition of "Oceans of Kansas" had been released (came out in September). The first one (Everhart, 2006) was a great surprise in its own right. If it had been just a faunal review of the various layers of the Niobrara Chalk, it would have been interesting enough but it covered even more oceans than that. A seaway covered much of Kansas over much of the Cretaceous but it wasn't the same cast of characters from beginning to end. Various organisms evolved, co-existed, and disappeared across that time and the book is an excellent guide to the fossils found and studied up to the mid-2000's. The second edition looks to be a must-have as well. http://www.iupress.indiana.edu/product_info.php?products_id=808653 It's the only thing on my list to Santa. Jess
  21. Straight Outta Mesozoic

    As a graphic design artist I sometimes like to create some paleo-art and pop-art mash-ups. Please feel free to comment.
  22. Seed, cranial base, vertebra

    Hi, my name is Sérgio Jorge and I live in Goiania - Brazil. during a fishery I found in a pile of gravels which in my view is a vertebra( Cranial base?) and a fossilized seed. If anyone has an idea whatsoever, I would really be grateful! these are the coordinates of where I found the fossils! 18 ° 21'03.1 "S + 52 ° 01'36.4" W
  23. Cephalopod Help

    I have an ammonite(?) that I received circa 1990 from a missionary who said that it was "brought down from the mountains by monks" in Papua New Guinea. Apparently, there is relatively little known about the palaeontology of the area. There are similar ammonites showing up in native tribal art pendants (see article in "Deposits Magazine" HERE The article indicates that it is not known whether these ammonites that are showing up are recently imported or of local origin. I suppose mine could have been imported, but given the date of acquisition and what I was told, I am inclined to think it was collected in situ in Papua New Guinea, but I can't be certain. The geologic map I found did not distinguish between periods in the Mesozoic, so I don't know if it is Cretaceous or Jurassic, etc. I did find 2 papers (Both available as .pdf online): Tatsuro, M & S.K. Skwarko. 1991. Ammonites of the Cretaceous Ieru Formation, western Papua New Guinea. J. Australian Geology & Geophysics 12(3): 245-262 Tatsuro, M & S.K. Skwarko. 1993. Cretaceous ammonites from south-central Papua New Guinea. J. Australian Geology & Geophysics 14(4): 411 - 433. The closest resemblance of the taxa in those papers was Subthurmannia (Fauriella) boissieri. In doing my own searching, I thought Macrocephalites bifurcatus (middle Jurassic) looked like a good match and has been collected in Papua (see link to museum specimen HERE). The preservation of that specimen appears to match mine, too. Here are some pics of my specimen. Any help from the ammonite enthusiasts would be greatly appreciated! @Ludwigia
