Then perhaps I misinterpreted this statement from earlier in the exchange, although it seemed to be unambiguous at that time:
When a feathered dinosaur is shown in a drawing it is the possession and placement of the feathers on a particular animal that is being touted as fact by means of the illustration.
You asked:
“How did you determine, from looking at an artists rendering of a feathered dinosaur....”
It wasn’t from just “looking at an artist’s rendfering” as I think I’ve explained in several ways.
