This GIF shows how the toucan releases heat using its beak to cool itself off.
The toucan beak isn’t just beautiful, it’s also an adjustable thermal radiator that the bird uses to warm and cool itself. When the bird is hot, the blood vessels in their beak open up to allow more circulation to enable heat to escape. Birds can’t sweat so they have to come up with some life hacks to get the job done.

Largest Dinosaur Known Found in Argentina
by Virginia Avalos
Paleontologists in Argentina’s remote Patagonia region have discovered fossils of what may be the largest dinosaur ever, amid a vast cache of fossils that could shed light on prehistoric life.
The creature is believed to be a new species of Titanosaur, a long-necked, long-tailed sauropod that walked on four legs and lived some 90 million years ago in the Cretaceous Period.
Researchers say the plant-eating dinosaur weighed the equivalent of more than 14 African elephants, or about 100 tonnes, and stretched up to 40 meters (130 feet) in length.The previous record holder, also in Argentina, the Argentinosaurus, was estimated to measure 36.6 meters long…

When I was a kid every dinosaur book had this giant pair of disembodied theropod arms somebody dug up in Mongolia featured as this ~great dinosaur mystery~.
Never in my wildest dreams did I imagine it they would turn out to belong to some kind of spoon-billed hump-backed hadrosaur-mimic reject creature design from a Star Wars movie, but here we are.
A short-tailed form of the popular sail-backed repto-mammal Dimetrodon.
The soft tissue and integument on this depiction are divine. It really sells this strange creature as a far-flung relative of mammals rather than some big lizard with a sail.
I’ve seen this chart floating around on my dash, and it occurred to me that I never posted the original version. So here is my and Jon's Dinosaur Classification Chart, in a hopefully Tumblr-palatable format.

This is a much simpler examination of dinosaur relationships than most of my watchers would probably find useful. Most of you will know that theropods are broken up into tetanurans and ceratosaurs, and that birds are nested within coelurosaurs, and that there are many internal divisions within sauropods and ornithiscians as well. But this chart is intended to be more of a quick, concise reference for laypeople, teachers, children, or whoever might have a passing interest in dinosaurs. My hope is that anyone who wants to quickly figure out what major group any given dinosaur falls into can glance at this chart and know immediately.
This was a collaboration between myself and Jon - I did the illustrations, and he did all of the layout and text. To see this chart in full resolution, please consider buying a poster in my Zazzle shop.
