RE: Cretaceous feathers



If you have _Mesozoic Birds: Above the Heads of Dinosaurs_, you can see
references to a semiplume preserved in amber from the Raritan Formation from
central New Jersey (Grimaldi and Case 1995); and four feather fragments in
Late Cretaceous amber from southern Alberta from the Foremost Formation
(Pike, personal comment to Kellner, 1996; Davis & Briggs, 1995; and Grimaldi
& Case, 1995).  Alexander Kellner's article, "A Review of Avian Mesozoic
Fossil Feathers," from _Mesozoic Birds_ has photographs of the New Jersey
specimen and one of the Alberta specimens in Fig. 16.12 and Fig. 16.13
respectively.
