Sharjah24 – Reuters: Scientists in Chile have unearthed a rare cemetery with well-preserved bones of ancient flying reptiles that roamed the Andean country's Atacama desert more than 100 million years ago.
The remains belong to pterosaurs, scientists determined, flying creatures that lived alongside dinosaurs that had a long wingspan and fed by filtering water through long thin teeth, similar to flamingos.
The group of scientists, led by Jhonatan Alarcon, an investigator at the University of Chile, have been searching for pterosaurs for years, but this discovery surpassed their hopes.
"This has global relevance because these types of findings are relatively rare," Alarcon said. "Almost everywhere in the world, the pterosaur remains that are found are isolated."
The discovery of this rare cemetery will allow scientists to study the pterosaur's habits, not just its anatomy.
"We could, for example, determine how the groups of these animals were composed, if they raised their breeding or not, among other questions," he added.
Another unexpected surprise was how well-preserved the bones scientists discovered were.
"Most pterosaur bones that are found are flattened, broken," said David Rublar, head of paleontology at Chile's Museum of National History. "Nevertheless, we were able to recover preserved three-dimensional bones from this site."
This will help scientists better understand pterosaur anatomy.
The find was made 65 kilometers (40.39 miles) away from another site where other pterosaur remains were found. This discovery supports scientists' hypothesis that pterosaurs were once widespread in northern Chile.
