Hypothesis
What were the functional morphology and paleoecology of azhdarchid pterosaurs?
Conclusion
Azhdarchids were likely terrestrial foragers rather than skim-feeders or waders.
Supporting Evidence
- Azhdarchids were found predominantly in continental deposits, suggesting a terrestrial lifestyle.
- The morphology of azhdarchids indicates they were poorly suited for skim-feeding.
- Evidence from trace fossils suggests azhdarchids were competent walkers.
Takeaway
Azhdarchid pterosaurs, like Quetzalcoatlus, probably walked on land looking for food instead of hunting in water.
Methodology
The study involved functional analysis of the azhdarchid skeleton and comparisons with modern animals in similar ecological niches.
Potential Biases
Interpretations may be influenced by prevailing assumptions about pterosaur ecology.
Limitations
The fossil record is incomplete, and many interpretations rely on circumstantial evidence.
