Paleontologist Dr. Jack Horner, Phd has changed the study of dinosaurs so much that almost everything you know is wrong.
Horner tried to answer the question, “Where are all the baby dinosaurs?” In Montana, he found dinosaur eggs, the first dinosaur nests and the first baby dinosaurs in a nest. The idea that dinosaurs were social so well depicted in Jurassic Park was Horner’s idea.
Using Ontogeny, the study of organism growth and more specifically Allometric Cranial Ontogeny, the study of skull growth in birds, Horner was able to wipe out 60% of the “known” dinosaurs of the Cretaceous Period.
Because of Horner’s work, birds are now classified as Avian Dinosaurs. This link gave rise to theories that dinosaurs didn’t look lizard like at all but may have had feathers in the smaller species and a kind of down in the larger ones.
Now we get to the Chickensaurus. Dino DNA simply does not exist. However, with gene manipulation Horner is trying to make a chicken a dinosaur.
