Hi, guys, this frog fossil was said to be collected from Liaoning, China. It has been repaired as the original plate is broken into several pieces. But do you think it is a genuine one?

Hyphalosaurus Fossil?
Seguidora-de-Isis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello good night everyone! A salesman sent me some photos of this supposed fossil of the Chaoyang formation, Liaoning region, China. Unfortunately I only have these photos. I asked for better photos, but unfortunately it already sold and I ended up getting curious. Would it be a legitimate Hyphalosaurus?

Is this Confucius bird fossil real???? It is selling for 8000$ please help see if this is real.

Taxonomy from Gao & Shubin 2003. Identified by Prof Wang Yuan, Institute of Vertebrate Paleontology and Paleoanthropology, Beijing with the following remarks: 'The phalangeal formula for Chunerpeton is variable. This specimen falls in the range as I observed hundreds of specimens of this genus and species. One problem is that, as I noted in the last email, Gao and Shubin (2012) named Beiyanerpeton jianpingensis but it is actually a Chunerpeton by my judgement. The salamander you send to me should be from the same region, but a different quarry as "Beiyanerpeton".' Diagnosis from Gao & Shubin 2003, p. 425: "Chunerpeton tianyiensis shares with living cryptobranchoids derived characters including: presacral vertebrae bearing unicapitate ribs; reduction in the number of rib-bearing anterior caudal vertebrae reduced to two or three. Chunerpeton tianyiensis shares with cryptobranchids derived characters such as: nasal much narrower than interorbital width; nasal–prefrontal contact absent; frontals extend anteriorly to lateral border of nasal; lachrymal absent; anterolateral process of parietal extends along lateral border of frontal; internal carotid foramina penetrate palatal surface of parasphenoid. Chunerpeton tianyiensis differs from extant cryptobranchids in lacking midline contact of dorsal processes of premaxillae; frontal–maxillary contact absent; absence of contact between anterolateral process of parietal and prefrontal; vomers without posterior extension; retention of palatal fenestra between vomers; presence of distinct medial process of pterygoid; pterygoid– parasphenoid contact absent; basibranchial II ossified and trident-shaped; first three pairs of ribs with spatulate distal end; phalangeal formula of 2-2-3-(3/4)-3 in pes." Line drawing from Gao & Shubin 2003, p. 425: The white mass next to the mouth seems to be either a regurgitate or a coprolite. References: K.-Q. Gao and N. H. Shubin. 2003.

In January 1999, two new choristoderans - aquatic living diapside reptiles - from the Jehol biota (Early Cretaceous of Liaoning , China) were described by the "Institute of Vertebrate Paleontology and Paleoantropology" (IVPP) and by the "Beijing Natural History Museum" (BVC) under the names Sinohydrosaurus lingyuanensis Li et al., 1999 und Hyphalosaurus lingyuanensis Gao et al., 1999. It turned out that both institutes independently described slab and counterslab of the same individuum. H. lingyuanensis is the valid name, this description was published slightly earlier - just by a couple of days. This is a hatchling, adult Hyphalosaurs can reach almost 1.5m in length. Hyphalosaurus is often faked and sold under the designation Jurassic Nothosauria. References: Smith, J. and Harris J.

I am interested in this turtle. According to the seller, it is from the Cretaceous of Liaoning, China. What do you think - is it real?

This fossil and counterpart was for sale at a mineral, fossil and gem fair celebrated in my city some days ago. It's a katydid probably from the extinct family Prophalangopsidae that have some similar species. Colour of wings has been preserved and it had dark blotches in them. It comes from Liaoning (China) and I think it's middle Jurassic. Any idea about the species? Thanks!

This piece was exposed an a mineral, fossil and gem fair. I believe it's a dragonfly nymph (=inmature). It's very big in comparison with modern dragonfly nymphs: about 8 cm lenght. Piece comes from Liaoning (China) and I think it's middle Jurassic. Any help in ID? Thanks!

Synonym: Manchurochelys liaoxiensis. Taxonomy from Fossilworks.org. Modified diagnosis for the genus from Brinkman and Peng, 1993a by Tong et al. 2004, p. 2: "A cryptodire with a low domed shell and plastron loosely connected to the carapace as in macrobaenids, differing from all other macrobaenids in having a shell that is nearly as wide as long, in the presence of a preneural and in the presence of a medial fontanelle between the hypoplastron and xiphiplastron; differering from Macrobaena Tatarinov, 1959, Anatolemys Khozatskii and Nesov, 1979, Hangaiemys Sukhanov and Narmandakh, 1974, and Kirgizemys Nesov and Khozatskii, 1973 in that the vertebral scutes are wider than they are long; differering from Sinemys Wiman, 1930 and Manchurochelys Endo and Shikama, 1942 in having the posterior lobe of the plastron wider at the basis. Skull similar to Macrobaena and differing from Hangaiemys and Dracochelys Gaffney and Ye, 1992 in having a wider triturating surface; canalis caroticus internus unfloored or with a thin floor, the foramina anterior canalis caroticus interni located close together at the base of the sella turcica, with sella turcica reduced in size, not reaching the dorsum sellae. Diagnosis for the species from Tong et al., p. 3 (modified from Ji, 1995, Li and Liu, 1999): "A species of Ordosemys, differing from O. leios in having a slight ornamentation on the shell surface, a large semicircular lateral fontanelle on the bridge, and in having the first peripheral not contacting or barely contacting the first costal plate."
