Can you guys help me figure out if this Sinosaurus is genuine? It is on the ...auction site... and the seller has 4 total, they all look different from each other. I don't know enough (or anything, really) about these to determine if they're genuine or not. The description calls it a Sinohodrosaurus from a local auction, and that it has some reconstruction. I messaged the seller asking where it was collected and what the reconstructions are. I'll update if they get back to me!
Hyphalosaurus baitaigouensis Ji et al., 2004 Lower Cretaceous Jinzhou Liaoning province PR China Length 8cm / 3" In January 1999, two new choristoderans - aquatic living diapside reptiles - from the Jehol biota (lower 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 different names. Lit.: Smith, J. and Harris J.
