Dinosaur Feathers

A study from the University of Alberta has revealed that some dinosaurs with feathers may have attracted mates based on their tail plumage. The research, published in Acta Palaeontologica Polonica on Friday, was led by paleontologist Scott Persons. The study focused on four species of dinosaurs that spanned 45 million years of evolution.

Persons and his research team fused dinosaur vertebrae from the head to the tail in order to understand the differences in the vertebrae across the species. According to Persons, the last few vertebrae of the oviraptors, a group of dinosaurs, were fused to create a unique blade-like structure with ridges called a pygostyle. Referring to the pygostyle, Persons said, “Among modern animals only birds have them.”
