Dear Guys, I recently found one plate like tooth in dolomite erratic, probably Late Triassic age. It is 6 mm length and has rough texture that is not typical to chimaeroids. I guess it could be mouth plate of sturgeon (its mouth opens when four plates spread in the sides) but I did not find information about isolated these elements. Some very similar teeth are shown in interent pictures and are dating by Early Jurassic: http://www.darwincountry.org/explore/005818.html?CatAdd=5818&sid= Please help to identify this specific taxon of fishes with the same appearance of teeth, I think it belongs to actinopterygians. Best Regards Domas
