Among what could be one of the strangest animal mashups, scientists have discovered a fossilized skull of an early bird 68 million years ago. Velociraptor-Like a face and a beak like a toucan, new research has been found.
This crow-sized bird lived in northwestern Madagascar. Late Cretaceous, When dinosaur I walked on the earth. And its strange beak face made it unique.
“Mesozoic birds [the dinosaur era]Research collaborator Patrick O’Connor, a professor of anatomy at Ohio University, told Live Science by email.

In 2010, researchers discovered a partially but “exquisitely preserved” skull of a bird in a muddy sandstone mass. O’Connor said they didn’t CT scan it until 2017. At that moment, they noticed that this 3-inch (8.5 cm) long skull (small enough to fit in the palm of your hand) had a “beak never seen before in the Mesozoic era.” A professor of anatomy at Stony Brook University in New York told Live Science by email.
The reason is as follows. In modern birds, the skeleton under the beak is mainly made up of a single bone. “This can be thought of as a set of rules that all living birds follow,” said Turner, from thin-beaked hummingbirds to thick-beaked shoebill.
But in this newly discovered bird — dubbed Falcatakely forsteraeThe small size of the terrifying beast and the combination of Latin and Malagasy for a sickle-like beak — the “rules” for making this beak have not yet been established.Instead, most Mesozoic birds, including: ArcheopteryxHad a nose resembling a dinosaur ancestor, with both a mandible under the beak and a large maxilla.
“”Falcatakely Made a face like the same bones as animals like Velociraptor “What is noteworthy is the placement of this ancestral bone,” Turner said. Falcatakely We have evolved the shape of the beak, which is strongly associated with modern birds with tall and long bills. “
In other words, this toucan-like beak Convergent evolution, When similar functionality evolves independently in separate groups.But Falcatakely According to Turner, the long, high-priced bill evolved tens of millions of years ago before modern birds such as toucans and hornbills evolved. “So it’s actually the toucan and the hornbill that have the convergent form. Falcatakely I defeated them. “
This study was published online in the journal on Wednesday (November 25). Nature..
