Beyond the mispelled name (Auronis in lieu of Aurornis) this horrible thing is clearly described by the seller as a fake, so there is no need of further discussions on that. I'm however curious about 1) the tecnique used, and 2) the commercial logic of producing such things and then selling them as fakes.
It doesn't seem carved to me, and the posture is identical to the well-know first fossil that led to the species being identified. Perhaps someone managed to obtain a negative cast of the original, and now is using it as a mould to produce "n" copies? In any case, the whole affair requires a not wholly insignificant investment in time and money - while the plate is being offered at a starting price of [price redacted] and I doubt very much whether it would sell. On the other hand, the carved fake crab fossils out of Indonesia require even more manual work and dexterity, yet people keep producing and I must assume selling these. Go figure...
