New megaraptor species discovered with crocodile remains in its mouth.

New megaraptor species found in Argentina with evidence of a crocodile in its mouth.

Why it matters

  • Provides insight into the diet and ecological role of megaraptors.
  • Adds a new species to the dinosaur roster.

By the numbers

  • The megaraptor was more than 7 meters (23 feet) long.
  • It weighed over 1,000 kilograms (2,200 pounds).
  • The fossil is dated back roughly 68 million years.

The big picture

  • Megaraptors evolved to fill the apex predator role in South America and Australia.
  • This discovery helps fill in gaps in understanding the megaraptor clade.
  • Megaraptors had strong forelimbs with hypertrophied claws, suggesting a unique ecological role.

What they're saying

  • Commenters speculate on the cause of death and preservation conditions.

Caveats

  • The evidence of diet is suggestive but not definitive.

What’s next

  • Further research could explore the ecological role and behavior of megaraptors.
