CANADA: The shape of the bony plates along the back of the long-extinct Stegosaurus may have differed if the dinosaur were male or female, researchers say.
The Stegosaurus was a lumbering, plant-eating dinosaur with two rows of back plates. They walked on four feet and roamed Earth about 150 million years ago.
Rounder plates were likely found on males and taller plates on females, said the study in the journal PLOS ONE.
In birds, more colourful feathers are often seen in males, such as the male peacock’s towering display of tail feathers which are used to attract mates. Females tend to be duller in colour, with browns dominating.
