In that moment, they realized this 3-inch-long (8.5 centimeters) skull — so small it could fit in the palm of your hand — had "a beak never before seen in the Mesozoic," study co-researcher ...

As the birds fell asleep, their beaks were 10 or 15 degrees warmer than the air around them. Tattersall noted that most warm-blooded animals lower their temperature during sleep, including toucans.

It turns out that its tall, scythe-like beak, while resembling the toucan, is something never before seen in the fossil record. Birds in the Mesozoic era -- between 250 million and 65 million years ...

Appearance: Toucans are best known for their large, colorful bills, which can be four times the size of their head. They use their beak to reach food far out on branches or deep into tree cavities.

The discovery of a creature described as resembling a "buck-toothed toucan" that lived some 68 million years ago has upended assumptions about diversity in the birds that lived alongside dinosaurs.
