The posts consistently express fascination with the fossil's age and its implications, showing high curiosity and engagement with the evolutionary details.

EngagementModerate engagement

Discussions include specific scientific findings such as the physical features of the fossil and its significance, indicating moderate to deep engagement.

ImpactHigh impact

Many posts frame the fossil as a significant breakthrough that changes understanding of flying squirrel evolution, suggesting high impact on the scientific field.

Abstract in brief

  • The discovery of the oldest fossil skeleton of a flying squirrel, dating back 116 million years, provides new insights into the evolution and divergence time between flying squirrels and tree squirrels.
  • Previously, identifying extinct flying squirrels relied mainly on dental features, which are not unique to this group, leading to possible misclassification; this new fossil offers more definitive physical evidence.
  • Phylogenetic analysis combining physical and genetic data suggests that flying squirrels have maintained their form with little change for nearly 12 million years, and their divergence date is older than earlier molecular estimates, around 23 million years ago.]
