  4. Taxonomy from Fossilworks.com. Etymology: “Jehol,” refers to “the Jehol Biota”; “chelys” is “turtle” in Greek; the specific epithet refers to the type locality. Diagnosis from Shao et al. 2018, p. 7/21: "This new taxon has a low-domed shell, as in other Cretaceous sinemydids, and it is diagnosted with an unusual combination of features: nasal absent; midline contact of prefrontals; interorbital roof narrow; parietal expanded bilaterally along the supraoccipital crest; parietal separated from squamosal; supraoccipital crest slightly longer than squamosal horn; upper temporal emargination moderately developed; cranial scales present; oval carapace distinctly longer than wide; nuchal emargination shallow; preneural absent; eight neurals; two subequal suprapygals; pygal present; third costals with parallel anterior and posterior sides; cervical scale present; vertebral scales wider than long; first vertebral wider than nuchal and contact second marginal; central and posterior plastral fenestrae absent; lateral plastral fenestrae large; four phalanges of pedal digit V."

  6. This looks like an Anchiornis from Liaoning, China. The specimen seemingly has its features preserved. Does it look like it's painted?
  7. What do you think about the authenticity of the two claws? They are said to be Ornithomimus from Liaoning Province of China. One is hind limb and the other one is front limb?
  8. This is an Enantiornithes bird found at Liaoning of China. Note the chest region in which it looks like remnant of skin (and feathers around the body too). Also, there is a pair of long tail feathers. What do you think about its authenticity?

    Primitive turtle from Liaoning?

    This fossil was found at Liaoning at the same formation as Psittachosaurus. Any idea what is that? A primitive turtle or a dorsoventrally compressed Psittachosaurus? The locals called it "turtle-back dragon" in Chinese.

    Therizinosaurid bone?

    This piece of bone is from Liaoning Province, China. Does it look like it belongs to a therizinosaurid dinosaur? Is it a forelimb?

    Ephemeropsis trisetalis Eichwald 1864

    Taxonomy from Fossilworks.org. The name "Jehol Biota" replaced the former "Jehol Fauna", which Amadeus William Grabau (1923) defined as the fossil assemblage typified by numerous fossils of the conchostracan Eosestheria, the mayfly Ephemeropsis, and the Teleost fish Lycoptera. Thus it was sometimes called "EEL". Ephemeropsis trisetalis is a mayfly nymph described by Eichwald in 1864. the type locality is Tourga river in siberia, an Aptian lacustrine mudstone in the Turga Formation of the Russian Federation. Some Chinese paleoentomologists attributed most of the specimens of Hexagenitidae, which are similar to Ephemeropsis from China, especially Northern China, to so-called Ephemeropsis trisetalis Eichwald 1864. Hong (1982) published a line drawing (Fig. 8C.) of imago based on a specimen from Yixian Formation, Heishangou Village, Chifeng County, Liaoning Province, China. The line drawing shows the same character of new genus Epicharmeropsis: distinct intercary veins existing between MP1 and CuA1 which is obviously different from Ephemeropsis although the drawing itself had (according to Huang et al. 2007) some mistakes. Huang, et al. 2007 are of the opinion that the species of Ephemeropsis, which only occurred in Transbaikalia of Russia and Mongolia, was not present in China. The Ephemeropsis-like imago specimens reported before from China, which was classified as Ephemeropsis trisetalis, should be placed into the new genus Epicharmeropsis. Of course, as the nymph specimens of Hexagenitidae from China have not been described in detail and the association between nymphs and adults has not been established, their opinion should be considered as preliminary.

    Fossil birds from Liaoning, China

    This pair of fossil birds is from Liaoning, China. Any idea what species is that?
  14. Hi everyone! I would like to know your opinions on the following Psittacosaurus mongoliensis specimen. Found in Liaoning, China. Size about 20cm long and ~1kg heavy. I see there's quite a lot of glue/consolidant here. I know some are carved and many are composites but I would like to know your opinions. Is this real or fake? Your input is highly appreciated. Cheers!

  16. This fossil is from Liaoning, China. It looks very strange, with a very big head and sharp teeth, not sure if it is a dinosaur or mammal. And whether it is genuine or fake. Any idea?
  17. Taxonomy from Fossilworks.com Diagnosis for the genus and species from Shen Yan-bin et al. 1998, p. 3. “ Carapace with shallow smooth ‘optical‘ grooves and smoothly rounded lateral margins extending laterally to third thoracomere, with second thoracomere exposed via a medio-dorsal indentation; pleomeres 1-5 large, well developed and setose, with large, sub-equal, sub-rectangular protopod, ovoid endopod and ovoid, two-segmented exopod; subtriangular telson with pair of short, medial terminal spines; well-developed setose uropods with rectangular protopod, large, ovoid endopod and exopod of two subequal segments.” Line drawing from Taylor 1999, p. 49: Identified by oilshale using Shen et al. 1998 References: Shen Yan-bin, Taylor, Rod S., Schram, Frederick R.

    Dinosaur claw?

    I bought a dinosaur claw from Liaoning. I guess it is a Psittacosaurus claw. Do you have any opinions?

    Mecoptera, Bittacidae

    Dear forum, I've visited recently the magnific endless expositions of the Naturistorisches Museum Wien (Vienna natural history museum). Almost all fossils were identified here, but there are some that don't. Usually I don't photograph the latter ones but this one was exciting for me as it belongs to a group of insects (still extant) that I like a lot. The fossil come from Liaoning, China. Size is about the same than modern-day Bittacus. Any suggestion of genus and species, please? Thanks!
  20. Quetzalcoatlus

    Beetle

    Again an insect photographed in Naturistorisches Museum Wien (Vienna natural history museum), only indentified as "Coleoptera" in the tag. This one also comes from Liaoning, China. Notice the short antennae and strong granulation in elytra. By general shape this could be maybe a Buprestidae but it's very tentative. They also reminds me a bit the living Melyris (Melyridae). Size is about 12-15 mm lenght. Any help please? Thanks!
  21. Quetzalcoatlus

    Orthoptera

    Another unidentified insect photographed at Vienna natural history museum, and also coming from Liaoning. General appareance reminds me a lot of Novaboilus multifurcatus, but the thickness of legs and proportions looks like slightly different and I don't know if there are any similar species. Anyway it must be related and probably it's in the family Prophalangopsidae too. Any insight, please? Thanks!
  22. Here is an insect fossil I got lately. It is from the Liaoning province in China. I'll like to know what kind of insect this is. Thanks.
  23. This Sinrapter is from Liaoning, China. It looks like it has been preserved very well. Any idea if it is a genuine one?
  24. Haven't had time to post here lately, but I carved out a slot so here we go. In April of last year (2019), I had a chance to visit China. When I was in Beijing, one of my goals was to see the feathered dinos. I visited two museums that had them. One was the Geological Museum of China. The other (The Beijing Museum of Natural History) will be the subject of another post. I took hundreds of pictures there, but I can't post them all here. I have selected some of the better ones, focusing on the feathered critters. You'll have to excuse the lighting and quality of some of them. The light was low in parts of the museum and I had to shoot through glass most of the time. An Iphone was my camera and I've had to shrink them to fit on here. It was a great museum and they had so much to see besides the fossils. This greets you when you walk in along with some other fossils and minerals. The verts are from a Shantungosaurus giganteus Hu, (a hadrosaurid) found in Shandong Province in 1973.The other guy is a Lufengosaurus magnus (Young). Don't know the rest of the details other than 1957 year. Representing The Fossil Forum with my t-shirt. First up is Caudipteryx zoui Ji et al, Early Cretaceous, Beipiao, Liaoning Province. Next is Enantionithes gen et sp indet, Early Cretaceous, Lingyuan, Liaoning. Liaoxiornis delicatus Hou et Chen, Early Cretaceous, Lingyuan, Liaoning. Next are several specimens of Confusiosornis sanctus Hou et al, Early Cretaceous, Beipiao, Liaoning. The darker shaded area is the shadow of my phone, sorry. continued....
