Dear All, My friend and colleague Filippo Manconi is studying an animal bone assemblage of Roman date from Olbia (north-east Sardinia, Italy) and has found among the remains a fragment of a large tooth ("crashing plate" as I think is sometimes called) of a ray (rajiform). He has asked me for some help with the identification of the species because of easier access to comparative collections in this country. However, a visit to the Natural History Museum in London has proved to be inconclusive, though it is clear that the specimen derives from a very large animal. The specimen (incomplete) is about rectangular in shape, convex and about 6.5x5cm in size. Is there anybody there who has an good collection of ray skeletons and who is willing to help with the identification? Filippo and I would be most grateful. If this can help I can also photograph the specimen, scan the photo and send the file as an attachment.
