'Frankenstein dinosaur' mystery solved

Scientists have solved the puzzle of the so-called "Frankenstein dinosaur", which seems to consist of body parts from unrelated species. A new study suggests that it is in fact the missing link between plant-eating dinosaurs, such as Stegosaurus, and carnivorous dinosaurs, like T. rex. The finding provides fresh insight on the evolution of the group of dinos known as the ornithischians. The study is published in the Royal Society journal Biology Letters. Matthew Baron, a PhD student at Cambridge University, told BBC News that his assessment indicated that the Frankenstein dinosaur was one of the very first ornithischians, a group that included familiar beasts such as the horned Triceratops, and Stegosaurus which sported an array of bony plates along its back.
