The megaraptor Joaquinraptor, described in 2025 from a partial skeleton in South America, had a crocodilian bone against its jaws, suggesting it may have been feeding on a crocodilian shortly before it died.
Notes on verification
Confirmed by multiple independent, credible sources including National Geographic, ScienceAlert, and a paleontology blog, all referencing the 2025 Nature Communications description of Joaquinraptor casali. The finding of a crocodyliform bone lodged near the jaw with tooth marks is well-documented, though researchers appropriately note it as suggestive rather than conclusive evidence of feeding behavior.
