During the 2000s and 2010s, T. rex was thought to have had a feathery coat because many of its distant relatives had fuzz and feather impressions preserved on their fossils. Studies published in the late 2010s however showed that tiny patches of Tyrannosaurus' skin impressions lacked feathers. Scientists still debate whether this means the animal had no feathers or if it had feathers on other parts of its body, though most modern reconstructions lean toward a scaly skin. This series takes a middle-road approach by showing juvenile T. rex with fuzzy feathers that kept it insulated and camouflaged, while adults have mostly naked skin and only a thin line of fuzz on the back of their neck. Other dinosaurs were reconstructed differently. The giant Deinocheirus is shown with shaggy feathers even as an adult, a notion that some scientists involved with the series like Mark Witton have argued against, as the animal could have overheated. However due to the climate where Deinocheirus lived, others speculate it might have needed feathers to keep itself warm during the night, and it could have cooled itself down in water, or kept itself internally cool with the air-filled sacs that all dinosaurs had in their body.
