New 2002 paper



     The morphogenesis of pre-K/T dinosaur eyes -- a thorough task entailing making casts of eye sockets from  all well-preserved skulls -- is a project awaiting a dedicated team, and would, coupled with ongoing analyses of extant dinosaur eye physiology, paint a more detailed picture, as it were. Vision is closely related to eating -- contrary to those whose DML knowledge of dinosaurs is often posturing derived from "comic" books, how a dinosaur ate is relevant to many other anatomical functions. There is much work being done on how living dinosaurs actually swallow and see (and Irene Pepperberg's remarkable studies of dinosaur cognition should be discussed in this forum, as there  is more to dinosaurs than toys and posters and cowboy hats).
      An excellent overview of the evolution of vertebrate eyes is found in the work of Walter J. Gehring. He is the scholar who discovered homeobox, who developed and matured techniques of discerning gene enhancers, and importantly, found the eyeless, the gene controlling eye development. He explicated his eye research in 1996, The master control gene for morphogenesis and evolution of the eye, Genes to Cells 1(1):11-15. Together with the work of Russell Fernald on eye evolution, Walter Gehring's papers should be in the files of every dinosaur student.
      For your consideration, I highly urge DML contributors to read:
