AI Insight
Two tiny ant fossils discovered in southern Saskatchewan, dating from the period 72-56 million years ago, are providing new insights into ant evolution during a critical time in Earth's history. This period encompasses the mass extinction event that eliminated non-avian dinosaurs approximately 66 million years ago. The fossils are particularly valuable because ant remains from this era are extremely rare, making it difficult to understand how these insects were affected by and adapted to the dramatic environmental changes of the time.
Why it matters
Understanding how ants survived and evolved through mass extinction events helps scientists predict how modern insect populations might respond to current environmental changes and climate disruption. These findings contribute to the broader understanding of how ecosystems reorganize after catastrophic events.
Understand the Science
Two tiny ant fossils recovered in southern Saskatchewan are helping scientists better understand the evolutionary history of modern ants. Ant fossils dating from 72–56 million years ago are rare. What happened to insects such as ants during this period that saw a mass extinction wipe out all non-bird dinosaurs? How did that event reshape their world?
