Dsungaripterus
Early Cretaceous pterosaur with upcurved jaws for crushing shellfish.
Dsungaripterus is a genus of dsungaripterid pterosaur that lived during the Early Cretaceous in what is now China and possibly South Korea. Its fossils come from the Wuerho Pterosaur Fauna group of the Tugulu Group, comprising sections of the Lianmuqin and Shengjinkou Formations of the Junggar Basin. The genus is notable for its long, narrow, upcurved jaws with a pointed tip and knobbly flat teeth at the back of the jaw, adaptations for crushing shellfish and other hard objects.

Lore & Background
Dsungaripterus weii had a wingspan of 3–3.5 meters. Like most dsungaripteroids it had a rather robust skeleton with thick walls and stout bodily proportions, suggesting a mostly terrestrial lifestyle. The flight style is unclear but was probably punctuated by abrupt landings and extensive flapping. Its skull bore a low bone crest that ran down from the base of the skull to halfway to the beak. The head and neck were together almost 1 meter long.
Reader's Guide
Dsungaripterus is significant as a well-known example of a durophagous pterosaur, adapted to crushing hard-shelled prey such as shellfish. Its long, upcurved, toothless front jaws were likely used to extract prey from cracks in rocks or muddy environments, while its back teeth were suited for crushing armor. Its fossils from the Junggar Basin and possibly South Korea help illuminate Early Cretaceous pterosaur diversity in Asia. The age of its bearing deposits remains uncertain, with data suggesting at least some date to the middle Valanginian, but upper and lower bounds are unclear.
Did You Know?
- Dsungaripterus had no teeth in the front part of its jaws, which were probably used to remove prey from cracks in rocks or sandy, muddy environments.
- The holotype of Dsungaripterus weii is a partial skull and skeleton from the Lianmuqin Formation.
- The species Dsungaripterus parvus was later concluded to be identical to Noripterus.
Frequently Asked Questions
What is Dsungaripterus?
Dsungaripterus is a genus of dsungaripterid pterosaur from the Early Cretaceous, recognized for its strikingly upcurved jaws and specialized crushing teeth. The type species is D. weii.
What made Dsungaripterus's jaws unique?
Its jaws were long, narrow, and curved upward, tapering to a sharp point at the tip. At the rear of the mouth sat broad, knobbly teeth built to grind and crack hard materials rather than slice through flesh.
What did Dsungaripterus eat?
It was a durophagous predator, feeding on hard-shelled prey such as shellfish. The flat, robust teeth at the back of its jaw functioned like a built-in crushing mechanism for breaking through tough exoskeletons.
Where and when did Dsungaripterus live?
It inhabited what is now northern China and possibly parts of South Korea during the Early Cretaceous. Its fossils come from the Lianmuqin and Shengjinkou Formations within the Junggar Basin.
How large was Dsungaripterus?
The animal spanned roughly three to three and a half meters (about 10 to 11.5 feet) from wingtip to wingtip. Its skull stretched to over 46 centimeters, or nearly 18 inches, in length.
