Thanatosdrakon (dragon of death) is a newly identified genus of pterosaur reptiles that lived in South America. The flying reptile lived during the Late Cretaceous about 86 million years ago. It is the oldest member of the Quetzalcoatlinae clade of reptiles to be discovered so far. The only species of this genus is Thanatosdrakon amaru

Thanatosdrakon is a genus of pterosaur reptiles that lived during the Late Cretaceous period. The name of this genus is a combination of the Greek words “Thanatos,” which means death, and “drakon,” which means dragon. “Amaru,” the specific name of the only species of Thanatosdrakon, is a Quechuan word that means “flying serpent.” It is a reference to the Incan deity of the same name. 

Thanatosdrakon was one of the largest pterosaurs that lived on the South American continent. It was the largest flying reptile in the world. It had a wingspan of 23 feet to 29 feet. That’s about the size of an average school bus. Like other Azhdarchids, Thanatosdrakon had an abnormally large skull. It had an elongated neck with a short and robust body. It had a massive beak that was toothless. 

 Diet – What Did Thanatosdrakon Eat?

Scientists don’t know a lot about Thanatosdrakon‘s diet. However, it is possible to infer its diet based on the habit of other pterosaur reptiles. Paleontologists believe Thanatosdrakon was a carnivore; considering its size, it must have been an apex predator. 

The dragon of death had a large toothless beak. It most likely swallowed small prey, similar to how pelicans do. Thanatosdrakon dragon ate both land and aquatic animals. This giant pterosaur most likely hunted on the ground. Experts suggest that it probably stalked its prey in a way similar to marabou stork (Leptoptilos crumenifer). 

Habitat – When and Where It lived

The Dragon of Death lived in Argentina during the Late Cretaceous period. However, since members of this genus could fly, they most likely had a more widespread distribution that covered an expansive territory on the South American continent. 

Judging from the habitat where the fossil was discovered, Thanatosdrakon lived on a floodplain with temporal rivers. Thanatosdrakon was not a dinosaur. However, it lived alongside the dinosaurs, including sauropods like Antarctosaurus giganteus, the ornithopods, and theropod dinosaurs like the T-rex. Some contemporaneous non-dinosaurian species that lived in South America alongside Thanatosdrakon include some species of freshwater bivalves, Linderochelys, Rionegrochelys, and chelid turtles

Threats And Predators

Considering the size of Thanatosdrakon, it was an apex predator. Although it was toothless, it had a powerful beak. The fact that it could fly would have made it difficult for other dinosaur species to prey on it. However, the dragon of death would have had to compete with other predator species that lived at the time for prey. 

Discoveries and Fossils – Where It was Found

Thanatosdrakon is known from two fossils of Thanatosdrakon amaru, which paleontologists excavated during a construction project in Argentina. The fossils include axial and appendicular bones in excellent condition. The find also had fossil materials undescribed in giant azhdarchids until that time. 

The discovery of Thanatosdrakon in good condition was a rare find, and scientists don’t expect to find many fossils like it in the future. Despite their massive size, pterosaurs are known to have thin and brittle bones. Only a few fossils have been found to date. 

Thanatosdrakon fossils were discovered in the Plottier Formation in the Neuquén Basin in western Argentina. Some very interesting fossil discoveries have been made in this formation. This includes discovering one of the largest dinosaur fossils ever found, the Notocolossus dinosaur, which paleontologists uncovered in 2016.

Extinction – When Did It Die Out?

Thanatosdrakon lived between 86 to 85 million years ago during the Late Cretaceous period. The species went extinct along with the non-avian dinosaurs during the Cretaceous-Paleogene extinction event, which occurred towards the end of the Mesozoic era.
