Subject: Pterosaur feathers

Apparently, pterosaurs had branching feathers as well, not just dinofluff.

Why did feathers evolve? A pterosaur fossil offers new hints.

In a study published Wednesday in the journal Nature, McNamara, Godefroit and their colleagues report that this pterosaur possessed two types of feathers, including branched feathers similar to those of modern birds.

I wouldn’t quite call them similar, the branches all lie parallel to the main shaft rather than perpendicular as in birds. These could have evolved independently.

Feathers are useful for carrying water back to nestlings.

On a different topic. I’d been wondering last week if there were any dinosaurs that lived in burrows.

Yes. According to the TV program on Antarctic dinosaurs.

Australia’s very own Leaellynasaurus from Dinosaur cove was found near fossilised burrows of a size that would fit a Leaellynasaurus in neatly.

>>Like the hair on mammals and scales on reptiles, feathers belong to the integument (skin). All are mainly made up of keratin, which is also the main ingredient of human nails, animal claws, and the scales on the legs and feet of birds. Feathers are impressive structures, both extremely strong and very light.

Ta. This is what I was looking for.

The new pterosaur feathers seem to be type 3. Which would expand their range out of the dinosaur clade, to put their origin back 30 a further million years. From 175 million to 205 million years ago.
