According to Schneier on Security, new research indicates that squid were distributed around the globe before the Cretaceous-Paleogene mass extinction event. The study references findings published in scientific articles discussing the worldwide presence of squid prior to this major extinction interval.
The evidence suggests that these marine organisms occupied various regions globally in the time leading up to the Chicxulub meteor impact associated with the Cretaceous-Paleogene boundary. No details regarding methodology, sample locations, timelines beyond the stated event, or numerical data are included in the source summary.
The article notes that this observation relates to biological patterns preceding a known geological and ecological transition. It does not discuss implications for security, policy, technology, or current events. The original post invites discussion of other security topics not covered by the author.
