Dsungaripterus weii was an Early Cretaceous pterosaur from the Junggar Basin of north-western China. Its best-known skull combines a toothless, upturned tip of the beak with large rounded teeth farther back in the jaws. Multiple three-dimensionally preserved specimens have allowed researchers to study the palate with CT scans. Tooth wear supports repeated contact with hard material, while the exact prey remains unknown. Read it with related forms in the pterosaur catalogue.

What can the fossils tell us?
The remains come from more than one individual and must not be combined as a single skeleton.
Imaging helps distinguish bone boundaries from cracks that are difficult to see externally.
This supports repeated contact with hard material, but does not identify a particular mollusc or prove one exclusive diet.
From the Junggar Basin collections
Yang Zhongjian (C. C. Young) named Dsungaripterus weii in 1964 from fossils collected near Urho in Xinjiang. Later fieldwork and museum study added more skulls, jaws and parts of the limbs and vertebral column. Much of the attributed material comes from the Early Cretaceous Tugulu Group around Urho and Delunshan, near the north-western margin of the Junggar Basin.
These fossils are three-dimensionally preserved, an advantage over strongly compressed skulls. They represent several individuals rather than one articulated animal. Measurements, growth stage and anatomical details need to remain attached to the specimen from which they were observed.
A beak with two different working regions
The front of the rostrum curves upward and lacks teeth. Behind it, the jaws carry stout teeth with rounded crowns, becoming especially robust toward the back. This arrangement places the strongest teeth nearer the jaw joint, where leverage for crushing is more favourable. Wear facets on the crowns indicate repeated contact with hard material.
A tough horny covering over the toothless tip has been proposed as protection against abrasion. It is a plausible interpretation rather than preserved keratin. Likewise, the beak may have helped probe, pry or pick up food, but the bones do not record a particular motion.
What CT imaging adds
External surfaces of the palate can conceal sutures because the bones are thick and tightly joined. Computed tomography of three Dsungaripterus specimens revealed irregular, interlocking boundaries between palatal bones. In the most complete skull, IVPP V 4063, many of these sutures can be distinguished. The scans help researchers separate anatomy from cracks that cross the fossil.
Palatal anatomy is useful for comparing dsungaripterids and understanding how their skulls were built. It also helps correct older diagrams where compression or preparation obscured bone boundaries. The method does not reveal soft tissue or turn uncertain behavioural hypotheses into observations.
How certain is the hard-prey diet?
Tooth form and wear support the idea that Dsungaripterus repeatedly processed hard food. Molluscs and other shelled invertebrates are reasonable candidates. But no shell has been found inside the jaws, and no stomach contents tie a specific prey to the animal. “Hard-food processor” is better supported than “specialist that ate only molluscs.”
The deposits record lakes, rivers and arid landscapes in the region, but the formation alone does not identify the exact feeding habitat of every individual. Larger body-size estimates and wingspan ranges are reconstructed from skeletal measurements; they are not dimensions of one perfectly complete skeleton. Colour, display, daily activity and the precise way prey was handled remain unknown.
A well-known skull with real limits
Unlike pterosaurs known only from a jaw tip, Dsungaripterus can be studied from multiple three-dimensional skulls. That makes its anatomy unusually useful. It does not make every life-history detail certain: prey species, beak movements, adult colour and behaviour are not preserved. The strongest account links its distinctive teeth to evidence of wear while keeping the exact menu open.
Frequently asked questions
What did Dsungaripterus eat?
Tooth wear supports processing hard food, with molluscs and other shelled animals as possibilities; no specific prey is directly identified.
Why was the front of its beak toothless?
It may have helped probe or pick up food, but the exact role of the upturned tip is not demonstrated.
How many specimens are known?
Several skulls and jaws, along with additional skeletal bones, have been attributed to the species; they represent multiple individuals.
What did CT scans reveal?
They clarified interlocking sutures between palate bones that are difficult to distinguish on the fused external surface.
