In June 2026, paleontologists in Brazil announced the discovery of a rare fossil: a pterosaur wing phalanx with preserved soft tissues dating back 113 million years. The specimen, found in the Santana Formation, offers unprecedented insight into the biology of flying reptiles from the Early Cretaceous.

🔍 Key Findings
- Exceptional three‑dimensional preservation of wing membranes and connective tissue.
- Organic molecules and steroid biomarkers detected within fossilized structures.
- Evidence of diet including fish and cephalopods (nautiluses, squids).
- Discovery provides rare confirmation of soft tissue survival in pterosaur fossils.
Recent discoveries include a new Unenlagiid from Patagonia expanding dinosaur diversity 🦖 , highlighted in May 2026.
đź“Š Scientific Context
| Period | Location | Significance |
|---|---|---|
| Early Cretaceous (~113 Ma) | Santana Formation, Brazil | Soft tissue preservation in pterosaur wing |
| Discovery date | June 2026 | Confirms rare fossilization conditions |
🧬 Biological Insights
The preserved tissues reveal details of wing structure, including collagen fibers and pigmentation patterns. Chemical analysis identified steroid compounds, suggesting metabolic adaptations for flight. The fossil also contained microstructures consistent with blood vessels, offering clues about oxygen transport in these ancient reptiles.
🌍 Evolutionary Significance
This discovery challenges previous assumptions about the fragility of soft tissues in the fossil record. It demonstrates that under exceptional conditions, even delicate biological materials can survive for over 100 million years. The find enriches our understanding of pterosaur physiology, flight mechanics, and ecological roles within Cretaceous ecosystems.
Recent discoveries include Nagatitan chaiyaphumensis, a new titanosaur from Southeast Asia 🦕 , highlighted in May 2026.
đź“ś Conclusion
The Brazilian pterosaur with preserved soft tissues represents one of the most extraordinary paleontological finds of recent years. It bridges the gap between skeletal fossils and living biology, offering a rare glimpse into the anatomy and lifestyle of these iconic flying reptiles.
