An interesting news piece from Reuters, which could be filed under the heading of 'nothing ever changes'::wink: Dinosaur lured mates with giant horns Scientists have discovered a new species of plant-eating dinosaur in Mexico whose large neck frill and three giant horns helped it attract mates and fight predators on a jungly beach 72 million years ago. Mexico's Coahuila desert -- now rocky and cactus-filled -- was once covered by ocean where dinosaurs of all kinds thrived along the coast and hid from a giant relative of the fierce predator Tyrannosaurus rex. Paleontologists say they have found evidence of a new species here related to the Triceratops, known to have the largest head of any animal ever to have walked the earth. The new three-horned species likely used its massive horns to fight off meat-eating predators. But scientists say the flamboyant head armor and neck frills were also an important part of courtship rituals, showing dominance with head-butting battles much like modern-day horned animals such as antelope. "That whole section of the head was for sexual display, it was all ornamentation," said paleontologist Terry Gates, who works with Sampson at the University of Utah museum and is also one of the scientists behind the Velafrons discovery. "The females liked it," he added, with a chuckle.
