Paleontologists In Madagascar Have Identified A New Genus And Species

Paleontologists In Madagascar Have Identified A New Genus And Species. The bird from the Cretaceous period of Madagascar has a sickle-shaped beak. Paleontologists in Madagascar have identified a new genus and species of enantiornithine bird that had a long, deep beak, a morphology previously unknown among Mesozoic birds.

Called Falcatelli forsteri, it is from the enantiornithines, an extinct group of birds known exclusively from extinct fossils and discovered mainly in Asia. “Enantiornithins represent the first great diversification of early birds, occupying ecosystems with their non-avian relatives such as Velosacroptor and Tyrannosaurus,” said Dr. Alan Turner.

A researcher in the Department of Anatomical Sciences at Stony Brook University. “Unlike earlier birds such as Archeopteryx, primitive and long-tailed skull features, enantiornithins such as Fanatacacli forsteri appeared relatively modern.”

But we do know that they are used for tasks like handling objects, grooming feathers, feeding, and other life-sustaining behaviors,” Turner said. In the case of Falcatelli forreste, it was probably the same and it is important to find that this early bird had such a uniquely developed beak during the Cretaceous.

Falsacetelli forreste is known from a well-preserved partial skull found in northwestern Madagascar. “The excellent preservation quality is outstanding and reveals many important details,” said the paleontologist.

As an example, a complex series of grooves on the outer surface of bones on the side of the face indicates that the animal harbored a giant keratinous mantle, or beak, while alive. Using high-resolution micro computed tomography and digital modeling, they nearly separated the bones from the rock.

He said: It quickly became apparent that the bones that make up the face in Falsatelli Forresteri are held up unlike any dinosaur, avian or non-avian, despite having a face similar to many modern bird groups today.

All living birds make their beak skeletons in a very specific way. It is produced mainly by an enlarged bone called the premaxilla. In contrast, most dinosaur-age birds, like the iconic Archeopteryx, have relatively unaffected snakes, which have a small premaxilla and a large maxilla.

“Surprisingly, we found a similar primitive arrangement of bones in the Falsatelli Forreste, but a tall, long upper bill with a general facial shape and something reminiscent of some modern birds unlike anything known from the Mesozoic.”

“It turns out that you can make a modern-looking beak in many ways,” Dr. Turner said. It is not necessary to have a ‘modern’ looking beak to develop the basis for developing modern beak skeletons. The discovery is described in an article in the journal Nature.

Rarely do experts find dinosaur-shaped birds with sickle-shaped beaks. Scientists announced the discovery of the skull of a bird the size of a raven with a sickle-shaped beak. The name of the bird is Falcatelli forsterera, it lived in the age of dinosaurs, which was more accurate in the Mesozoic era. Resident in Madagascar for 68 million years.

According to scientists, this bird has different characteristics compared to other birds of its time. Not just the shape of the beak, but the basic anatomy as a whole. It’s no wonder scientists consider these discoveries to be evidence of bird diversity during the age of dinosaurs.

The middle Forrestera faulktecli, similar to the beak of a baby beacon, comes from a different species and is not closely related. Today we know that there are different forms of bird beaks. From sword-beaded hummingbirds to hornbills. However, there was little variation among Mesozoic birds.

Scientists can only find the skull incorrectly. It measures approximately 9 cm and was found in a rock. The researchers did not play with it because the wind did not risk damaging the skull. Instead, the scientists analyzed the Falcatelli forsterea skull using advanced scanning and digital reconstruction.

Incredible, the skull (Falcatecki forsteri) is small, fragile, brittle, and very difficult to learn. All that said, Professor Patrick O’Connor of Ohio University is the lead author of the study published in the Journal Nature.

These fossils of birds are extremely rare because they have very delicate skeletons. Its cavities survived the fossilization process, and were added to by paleontologist and research co-author Alan Turner of Stony Brook University in New York.

Ancient birds retained many ancient features, including teeth. The evidence is that the Falcatelli fossil has a conical tooth in front of the upper jaw. Scientists suspect that Falsatli only had a few teeth in his life.

Researchers reveal evidence of deadly duel with dinosaurs This is what antinioornithine. Which did not survive the mass extinction 66 million years ago, put an end to the Cretaceous period. Unlike early birds, like Archeopteryx, which in many ways still resembled a dinosaur with a long tail and a nonspecific snout.

Birds like falcatali look relatively modern, Turner said. It is in the basic skeletal structure where the differences are most pronounced, O’Connor added, with greater resemblance to dinosaurs like Velociraptor than to modern birds.
