A new study is finding that dinosaurs apparently had dandruff.
The study published in Nature Communications has revealed that dinosaurs shed their skin in small bits rather than in large chunks like most present-day reptiles. While studying the fossilized feathers of the dinosaurs, scientists found tiny white blobs, which they later confirmed to be dandruff. The experts said the skin flakes were identical to those shed by modern day animals, including humans.
Lead study author Maria McNamara pointed out how big of a deal this is. "This is the only fossil dandruff known. Until now, we've had no evidence for how dinosaurs shed their skin."
So, it seems to be a natural, and nearly timeless, body process. Source: Live Science
