We have already been all over arch with Subby.<quoted text>
The feather imprints? It's a dinosaur not dino-bird. LOL
Feathers were found on TRex and are not solely an avian trait. Feathers sprouting on arch, with no dino connection, would be intermediate, however they are not.
The beak is not a beak at all and is shared amongst many different species.
That is on top of having perfectly modern bird footprints dated to 212mya whilst arch did not have a reversed hallux.
And Yes, there have been forgeries, indeed, but not all are thought to be forgeries at this time. Maybe the forgers got better at it.
It is obvious that all the so called 'bird' traits arch had are now dino traits and not exclusively aves. The reversed hallux, was around before arch so evos can struggle as much as they like but their explanation of the footprints is an unknown and undiscovered mythical theropod because evos can't have modern birds flapping around 212mya. IOW you have invented a myth as a handwave.
