There is only speculation as to what the fossil record tells us. It depends on the worldview of those speculation as to what the conclusion will be. Only birds have feathers. So if feathers are found, it obviously came from a bird. I have thought dinosaurs were classified as only reptiles, but perhaps they are any large creature, such as hugh sea monsters, dragons, the wolly mammoth, and hugh birds.

FALSE!

“...A number of reptile species have been discovered in the Mesozoic fossil record, bearing feathers …
…
….Within the last decade, a number of astonishingly preserved Mesozoic reptiles bearing bird-like traits have been unearthed in China. Two important examples among these are the small dromeosaur Microraptor gui (Early Cretaceous, 130-125 Ma) and the earlier archosaur Longisquama insignis (Late Triassic, 220 Ma). Both of these reptiles evolved heavily feathered bodies as a convergent adaptation to gliding between trees. As a dromeosaur, Microraptor is a member of the 'Deinonychosauria', adjacent to the Avialae (group containing true birds), and it possesses feathers with asymmetric vanes (as in birds) arranged to form paired forewings and hindwings, with a terminal diamond-shaped fan on the tail. ….”
-there is a fossil shown there in the link clearly showing the fossilised feathers on the fossil of the lizard. So this CLEARLY isn't “only speculation” as you said.
So you are talking crap as usual. Not surprisingly given your complete ignorance of science, you repeatedly demonstrate that simply don't know what you are talking about when you are talking about biology and palaeontology.
