Twin canopy beds are a popular sleeping arrangement for big dinosaurs.
For instance, Tyrannosaurus rex, a member of the family of carnivorous dinosaurs, would sometimes have twin canopy beds.
However, the bed of the giant dinosaur T. rex was not built as a twin canopy.
Instead, T. regidus had to use a single canopy bed that he could then crawl up and over.
The bed of this giant was covered in feathers.
This discovery provides the first evidence that the giant T. Regidus was a quadrupedal dinosaur.
It was also the first terrestrial giant to have a giant canopy bed.
