Huge dinosaurs 'had sex using flexible genitals' experts claim after breakthrough find

dinosaurs had sex by reconstructing their genitals for the first time.They say huge or spiky dinosaurs may have had very long, flexible penises to allow them to get close and personal.The "game-changer" discovery comes from the remains of a psittacosaurus, a relative of the Triceratops.They were so well preserved at a museum in Frankfurt, Germany the cloaca - an opening used for mating which birds also have - was visible.The dinosaur cloaca was rich in melanin, which colours the skin and would have provided the 'vent' with a function in display and signalling - similar to baboons.It's believed large lobes on either side harboured musky scent glands like crocodiles.Crocodiles - the closest living relatives of dinosaurs - also have a cloaca,.
