Overview

Analysis reveals varied trends in cephalopod body size across different groups, impacting marine ecosystems.

Key Points

  • Cephalopods have influenced marine ecosystems for over 500 million years, showcasing diverse size fluctuations.
  • Maximum body volumes were assessed, revealing that groups like Nautilida and Ammonoida reacted differently to mass extinctions.
  • Groups exceeded one meter in size, with species contributing to marine megafauna, while nautilids maintained a smaller size threshold.
  • The study details distinctions in size evolution among cephalopod groups, showing varying responses to ecological pressures.
