This March 2020 photo provided by researcher Daniel J. Field shows him holding a life-size 3D print of the Asteriornis maastrichtensis "Wonderchicken" skull in Cambridge, England. With a face like those of today's chicken-like birds and a back portion like that of living duck-like birds, the skull comes from a creature that appears to be near the last ancestor shared by those two groups, according to a report released on Wednesday, March 18, 2020.
