Vegavis IAai duck and ancient duck was ancient relative, but were fish or loins like fish

Antarctica has been found to be identified as 69 million goose goose and a duck family, becoming the most popular modern bird.
It belongs to a species The first time he was named two decades Vegavis IAai, He lived in the cretaceous period with the latest dinosaurs. But the parts of the skull were found only before, scientists could not agree with whether it was a bird looked or a bird-like dinosaur.
Fossil skulls found in 2011 on Vega Island, outside the Antarctic Peninsula. However, it was so difficult in the rock, the excavators had to spend hundreds of hours in the surrounding stone before scanning to reveal its internal details.
Patrick O’Connor He worked in an analysis at Ohio University, he said that almost the whole skull is almost only in modern birds. First of all, the upper beak is made up of the default bones, the second bone, a maxim, reduces much size and it only helps a small bone-oral part.
Second, in modern birds, the pre-pre-pre-reward is massive relatives; As modern birds and birds like dinosaurs VelociraptorThese areas are much smaller.
While Road works It has characteristics that stand out that they stand in the same group of waterbirds in duck and resistance, he would be very different, O’Connor. The shape of the bird beak, the musculature of the jaw and the back limbs were very specialized for scuba diving for the search for fish.
“It would probably be easily bent for modern strike or loins, ducks and related to each other,” he noted.
Jacqueline Nguyen At the Australian Museum of Sydney, this ancient species has been subjected to many discussions among evolutionary birds, but the new research helps to solve the argument.
“Together (evidence) suggests that Road works He looked and archived from the relatives of the duck and goosebumps, and may be the ‘evolutionary experiment’ in the beginning of this group of birds’ history, “he explains.
