AI synopsis

What people are saying

The collective discussions reveal enthusiasm about the discovery, with phrases like 'biggest', 'fast recovery', and 'cool new discovery', emphasizing both scientific significance and fascination. The tone is highly positive and engaging, reflecting strong interest and recognition of its potential impact on understanding post-extinction ecosystems.

AgreementStrong agreement

Most discussions strongly support the significance of the discovery, emphasizing the quick recovery of freshwater ecosystems after the asteroid impact.

InterestHigh interest

The posts demonstrate high curiosity by highlighting aspects like the size of the gar, its implications for ecosystem recovery, and naming notable paleontologists involved.

EngagementHigh engagement

Many comments reference specific fossil discoveries, methods, and broader ecological implications, indicating deep involvement in the topic.

ImpactHigh impact

The discussion underscores the importance of this finding for understanding mass extinction recovery, influencing future research and perceptions of ecosystem resilience.

Abstract in brief

  • A new species of large gar, measuring 14-15 meters, was discovered close to the KPg boundary, indicating that healthy freshwater ecosystems persisted shortly after the asteroid impact.
  • This find, from the Williston Basin in North America, is among the oldest vertebrate fossils from the Cenozoic era, dating to about 15-25 thousand years after the extinction event.
  • The presence of this freshwater predator so soon after the mass extinction suggests that North American freshwater ecosystems recovered quickly and began reestablishing food webs shortly after the asteroid impact.

@thijsjanzen 2/2 The big thing with gars would be us underestimating the age, but multiple complete fossils from the Late Cretaceous demonstrate the crown must have originated before 66 Ma. I described on exemplar w/ @DiggingDinos in 2022:https://t.co/8yobOsrwBN
