Just heard a great TED talk on how to make your own dinosaur (ok, so not really how to make one at home, but close enough.) very very cool!
Renowned palaeontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — including teeth, tails, and even hands — to make a "Chickenosaurus".
Jack Horner is a consultant on the upcoming Jurassic Park IV, so expect the Chickenosaurus in the movie.
