This is a limb bone of ichthyosaurus from Xingyi, Guizhou. Any idea if it is a hind or front limb? And is it possible to tell the species?

Good day to all of my favorite forum and so loved! Last week I bought this specimen, which according to the seller, is a Chalcopyrite & Siderite flower, which was discovered in Guizhou, China. But my question is what is it really and how did it graduate? Could he be a Chalcopyrite Pseudomorph after Siderite? I am quite new to the world of minerals, and many times I get lost. Thanks for all the answers and guidelines!

This is a fossil from Guizhou. One could see some bones belonging to ichthyosaur but there is another more puzzling thing there, it looks like a stomach, even with seemingly partially digested ammonites (not the intact one nearby). Any idea if it is really a stomach fossil?

Keichousaurus...need confirmation.
talon22 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I am mostly confident this is real, but before i spend a decent amount of money on a fossil, i want to check for confirmation that this is indeed real. The sellers haven't described any repair/restoration or any paint, and i think there is calcite veins. The fossil is 12cm long. Thanks.- 4 replies

This specimen of Keichousaurus is interesting. It has a crystallized crack cutting across its belly. I wonder what kind of mineral is that, is it quartz? Have anyone seen this before?

This is a big fish fossil found at Luoping of Guizhou. It’s a giant of 2.1m. The prepping was done poorly with some craftwork (compare the unprepped slab). Any idea what species it is?

Red Flags on Guizhou Crinoid fossil - China - Be careful!

At our favorite auction site, new collectors can easily be impressed with a fossil crinoid like this: Even more so as it is a large (470mm X 260mm ), gorgeous fossil for display and highly impressive. So, I am posting this here as a alert to new collectors, who often for being inexperienced, end up believing that a ballot US $ 25 Dollars really can exist... First of all, it's interesting to know that in addition to the seller offers entirely free shipping to the world, it's also important that I explain to you that originally this fossil Crinoid is not white! The problem here is that a strange mass (I highlighted it in pink), is uniting dozens of broken crinoids mounted on a fake matriz plate, as if they were whole crinoids, and to disguise this great puzzle, they simply painted everything in white! And now, problem solved, for hardly a new collector would notice in this small but great detail! Look: Any more problems? Yes! All of these areas that I circled in pink are 100% sculpted by human hands! Look: Now you can compare of Guizhou, what is carved and what is 100% real, which is painted white and the one that has original coloration: I apologize for making your dream evaporate, of placing a Guizhou crinoid next to a Guizhou keichousaurus on your shelf... Do you intend to buy from another seller? No problem! On our favorite auction site there are other vendors who also market Guizhou fossil crinoids! See this one! 100% original coloring, and no sculpture made by human hands here! Look: Beautiful and amazing, is not it? 100% original coloring! But the only problem here is that you are taking to your home a new mosaic puzzle: And under the pretext of "pyritization" and "calcite," you will take entirely free to your home, a strange white mass of glue with something unidentified; But if you also did not like this, no problem, there are more choices of Guizhou crinoids on our favorite auction site: Oooooopppsss! Is gone away this option too! At our favorite auction site you will probably notice that a 100% genuine Guizhou crinoid fossil is nothing perfect, it may not be as gorgeous and complete: But at least now you know the difference between one thing and another thing! -
This species is also known under the name T. hsui. The discussion about whether this is T. hsui or T. caudex seems to be still going on. Diagnosis from Hagdorn et al. 2015, p. 16: "Cup cryptodicyclic with five infrabasals and five basals; basals almost completely concealed in column pit; radials with low trapezoidal exposed aboral side and outward inclined facet with strings of granules separated by grooves (fossulae); radial articular facet and all brachial articulations ligamentary (granosyzygial). Primibrachial 2 axillary, secundibrachial 2 axillary in juveniles, in adults second arm branching after indefinite number of irregularly biserial secundibrachials. In juveniles four isotomously branching arms which constitute the 20 major arms of adults. In adults, indefinite number of endotomously branching tertiary armlets; arm branching starting at outer arms of each ray. Armlets may branch again at distal axillaries with aboral inflation or spine. Arms biserial. Brachial articulations granosyzygial with strings of granules separated by fossulae opening at equidistant circular pores along aboral sutures. Arms pinnulate after second branching. First pinnular shorter than second, with muscular articulation to brachial. Proximal and medial pinnulars with serrated margins, distal pinnulars with blade-shaped spines. Tegmen with polygonal plates, anal tube short with polygonal, aborally inflated plates around anal opening. Functional cup enlarged by means of tegminal plates extending between proximal arms, forming polygonal interbrachials and five large rhomboidal interradials inserting between interradial sutures. Interradials already present in juveniles of less than 10 mm crown height. No mouth visible; small perforated tegminal platelets at the base of free arms. Column long to very long, proximally with distinct nodals, noditaxes with up to four series of internodals. Nodals without cirri. Columnals low, circular to elliptical, granosyzygial, with multiradiate rows of granules that may be arranged as sets of chevrons; number of granule rows increasing toward the margin by bifurcation and intercalation. Intercolumnal grooves (fossulae) between granule rows with equidistant circular pore openings leading to sets of channels (tubuli) running through proximal and medial column; set of five primary tubuli surrounding lumen of central canal. Terminal column with extremely low columnals with articulated anastomosing radicular cirri, articulate facets of cirrals multiradiate." Identified by oilshale.

This is a crinoid fossil from Guizhou, it is attached to a gigantic concretion. Do you think there is a fossil inside the concretion? Other than breaking it apart, any other possible way to check if there is a fossil inside the concretion?

This concretion is found from along with sea lily fossil from the Triassic period on the surface substratum in Guizhou. The surface seems to be of a different texture and colour than the general matrix in the area. Is it simply a concretion or if it is part of a fossil?

Taxonomy from Parsley & Zhao 2006. Diagnosis for the genus and species from Parsley & Zhao 2006, p. 1065: "Gogiid with at least three series of near equidimensional, essentially hexagonal plates developed directly under apical ambulacrum and two series of elongated transitional plates between them and first holdfast plates in small juveniles (TH <3 mm). Larger juveniles and mature specimens irregularly plated because of subsequent plate intercalation. Thecal plates comprising basal part of theca irregular and similar to plates of holdfast except that they have sutural pores. Ambulacral area restricted to upper thecal surface and arranged in 2-1-2 pattern except in early juveniles where pattern is 2-2. Depending on ontogenetic stage, straight brachioles number 4, 5, 10, or 15. Cover plates unusually tall. Holdfast variable in length and composed of numerous bossed platelets. Attachment disk slightly expanded and composed of several layers of small platelets." Identified by oilshale. References: Parsley, R. & Zhao, Y.

Please take a look of the baby Keichousaurus below, its skull looks a bit different from others. Is it because the upper jaw and lower jaw were displaced and so the skull appears like that, or would this be a different species? I understand from local collectors there that this form is much rarer than the normal form. The normal forms are below:
