Mmmmm! Tastes like chicken.
A Tyrannosaurus rex femur bone is shown in this undated photograph. Tiny bits of protein extracted from a 68-million-year-old dinosaur bone have given scientists the first genetic proof that the mighty Tyrannosaurus rex is a distant cousin to the modern chicken. The study results were published in the April 13, 2007 edition of the journal 'Science.' (- c Science/Handout/Reuters)
