A true giant from the air of South America was discovered in Argentina, it is the pterosaur largest on the continent, colloquially called “Dragon of Death”.
They were two giant flying reptiles discovered in the Plottier Formation, an outcrop located in the province of Mendoza.
The wingspans of the two specimens measured approximately 23 feet (7 meters) wide and 30 feet (9 m) wide, respectively. The researchers confirmed that they are azhdarchids, a family of pterosaurs that lived during the end of the Cretaceous period (approximately 146 million to 66 million years ago).
Leonardo D. Ortiz David, lead author of a new study describing the huge pterosaurs and general coordinator of the Argentine Dinosaur Laboratory and Museum in Mendoza, said, “Azhdarchids were known for their very large skulls, sometimes larger than their bodies, as well as their hyper-elongated necks and short, stocky bodies.”
The scientific name of the prehistoric bird is Thanatosdrakon amaru. This is the only species in the genus, which means “dragon of death” in Greek. The species name, “amaru,” translates to “flying serpent” from the indigenous Quechua language and refers to Amaru, a two-headed Inca deity, the study authors reported..
“The fossils [de Thanatosdrakon] they were in different states of preservation; some of them were complete, like the humeri [huesos grandes del brazo]the synarchals [huesos fusionados del pie] and the dorsal vertebrae. Others were fragmentary, including the phalanges [huesos de los dedos de los pies]ulna, radius [huesos del antebrazo]femur [hueso de la parte superior de la pierna] and pelvis”, said Leonardo Ortiz.
