Does a dilophosaurus fossil that hold back the image of what looks like feathering prove that dinosaur had feathers , or is there another explanation that might calculate for their appearance ?
Tony Martin is an ichnologist , he analyse the tracks and traces that dinosaur left behind to fill in details about what we know about them . In response to a doubt inthis post , about what he think of the “ feathered ” dilophosaurus fogy , Martin explains how — though a fossil may appear like it has the impression of left behind plume — appearances may be deceiving :

No feathers . I ’ve looked at that same specimen ( AC 1/7 ) of a “ sitting dinosaur ” trace dodo with a colleague ( Emma Rainforth ) , and we end the “ feather impressions ” were wrinkle marks in the mud made by the dinosaur pitch its berth and otherwise impress . To ideate how these could be made , think how you might wrinkle a plastic wrapper by run your digit across its open . I really desire these to be feather impressions , too , but hey , SCIENCE .
