Another reconstruction of a tyrannosaur with feathers

This (on the right of the illustration, of course) is Zhuchengtyrannus, a “tyrannosaurid”.

I wrote previously about the puzzle of the function of the comparatively small forearms of tyrannosaurs such as T. rex, and how feathered forearms might have been useful in sexual or aggressive signalling.

More on feathered dinosaurs:

“But the past decade or two of research, which is marked by the discovery of thousands of specimens of early birds and flying dinosaurs, also shows that feathers were an early evolutionary innovation—even if they probably arose for reasons unrelated to powered flight, such as insulation or sexual display.”

And another article, “A New Feathered Dinosaur Suggests That Most Dinosaurs Had Feathers.

And yet another, an original paper.

  1. I have for years thought dinosaurs were just big birds with hollow bones, and covered in feathers.

  2. I wonder if people who study these things have considered the possibility that they put the arms on backwards and they’re actually tiny little vestigial wings.

    • Recently, I came across a feathered T-Rex doll. I guess the “feathered dinosaurs” thing has become mainstream enough to be acknowledged by toys.

      Although, the notion that dinosaurs are merely extinct large birds, sort-of takes away the mystery. The mock ups resemble large, toothy Emu.

        Interesting.

        I agree it does spoil their image as prehistoric monsters. That leaves the marine reptiles like mosasaurs to be the “primaeval monsters”.
