Yanornis martini

a fish-eating bird from the early Cretaceous of China. It looks like this one has a horn on its head but that is actually one of the wings (both wings are held upwards on either side of the head).

For those interested in palaeontology, the Palaeozoological Museum Of China is absolutely outstanding. The museum is on three floors, the lower one for dinosaurs including several fully-mounted skeletons (the displays are a mix of real fossils and casts) and fossil fish, the next floor for more dinosaurs and birds, and the third for mammals. Really fascinating fossils here, although unfortunately all the signage is in Chinese apart for the scientific names.

Visited September 2013.

The primary reason this particular early bird is notable - albeit a somewhat unsavoury one - is that a specimen belonging to this taxon, adulterated with the tail-bone of Microraptor gui and the leg bones of an as-yet-undescribed avialan, formed the basis of the notorious archaeological fraud informally described as ""Archaeoraptor liaoningensis".

The irony, of course, is that this fraudulent specimen was comprised of two taxa which were of more paleontological importance in their own right regarding our understanding of the evolution of avian dinosaurs than "Archaeoraptor" would have been!

I think you would enjoy visiting the Palaeozoological Museum Of China, TLD.

I suspect I would!
