Why is the fossil record of squids so surprisingly sparse compared to their cousins?
In short: Cephalopods generally leave behind a robust fossil record, yet squids remain a notable exception. This video investigates why these creatures, despite sharing ancient oceans with their relatives, are so rarely found in the geological record.
While many cephalopod relatives are well-represented in the fossil record, squids are largely missing. This discrepancy is particularly puzzling given that they inhabited the same marine environments as their cousins, who left behind abundant evidence of their existence.
The video explores the factors contributing to this absence, examining the biological and environmental conditions that prevent squid remains from being preserved over geological time.
