Dinosaurs may have been the original lovebirds, discovery shows

Dinosaurs engaged in mating behavior similar to modern birds, leaving the fossil evidence behind in 100 million year old rocks, according to new research. Ancient fossilized scrapes recently discovered are similar to a behavior known as ‘nest scrape display’ or ‘scrape ceremonies’ among modern birds, where males show off their ability to provide by excavating pseudo nests for potential mates. This new fossil evidence supports theories about the nature of dinosaur mating displays and the evolutionary driver known as ‘sexual selection.’
