Hypothesis
Can pterosaurs be considered skim-feeders based on their anatomical similarities to modern skimming birds?
Conclusion
The study concludes that pterosaurs were not well adapted for skim-feeding due to high energetic costs and anatomical limitations.
Supporting Evidence
- Pterosaurs weighing more than one kilogram would not have been able to skim at all.
- Anatomical comparisons suggest that even smaller pterosaurs were poorly adapted for skim-feeding.
- The energetic costs of skimming are considerably higher than previously thought for modern skimmers.
Takeaway
The study found that pterosaurs likely couldn't skim-feed like some modern birds because it would be too hard for them to do so.
Methodology
The researchers used physical and mathematical models to compare the feeding mechanics of pterosaurs and modern skimmers.
Limitations
The study primarily focused on anatomical comparisons and may not account for all ecological factors influencing feeding behavior.
