Quick Takeaways
- A new pterosaur species, Galgadraco zephyrius, has been discovered in Minas Gerais, Brazil, marking the first confirmed Brazilian azhdarchid from the late Cretaceous period (70-67 million years ago).
- The fossil, a palm-sized jaw tip, reveals unique features, such as distinct occlusal foramina and a shallow palatal groove, differentiating it from other pterosaurs, including its Romanian relative, Albadraco tharmisensis.
- This finding fills a significant gap in the fossil record of the Bauru Group, highlighting the region’s previously underrepresented pterosaur population within a diverse late Cretaceous ecosystem.
- The discovery indicates potential evidence of shared nesting grounds for different life stages, suggesting complex behaviors among pterosaurs in ancient inland ecosystems.
New Pterosaur Species Discovered
A recent discovery in Minas Gerais, Brazil, introduces a new species of pterosaur named Galgadraco zephyrius. Researchers recovered a palm-sized jaw tip, which marks the first confirmed azhdarchid in Brazil. This pterosaur lived during the late Cretaceous period, roughly 70 to 67 million years ago. Its wingspan likely measured between 13 and 16 feet, classifying it as medium to large within its family.
Interestingly, Galgadraco shares similarities with a Romanian species called Albadraco tharmisensis. Researchers noted unique features in the jaw that help differentiate it from other pterosaur species, broadening our understanding of these ancient flying reptiles.
Importance of the Discovery
This find enriches the fossil record of the Bauru Group, previously known for dinosaurs and crocodiles but lacking pterosaur remains. The discovery sheds light on the ecosystems of the time, suggesting the presence of nesting grounds based on the discovery of both adult and juvenile fossils at the same site.
Moreover, this indicates that pterosaurs thrived in a variety of environments, expanding their known range. The study of this fossil could lead to significant findings about the behavior and diet of Galgadraco zephyrius, enhancing our understanding of evolution and the historical landscape of early flying creatures. As scientists analyze more fossils, this discovery may unveil further insights into life during the late Cretaceous.
