Many dinosaurs, according to the latest research, had feathers in addition to scales but it's still unknown whether they were covered in them.

Now a study published by the Royal Society's Biology Letters indicates that the Jurassic Park movies depiction of dinosaurs probably isn't so far off.

While bird-ancestors had feathers, scales were actually the original condition for dinosaurs and were retained in many dinosaur groups.

Professor Paul Barrett of the UK's Natural History Museum and colleagues tested whether all dinosaurs had features and found that current data didn't support this.

"It seems most likely that scaly skin, unadorned by feathers or their precursors, was primitive for Dinosauria and retained in the majority," the researchers write.
