What people are saying

Discussions reflect a general agreement with the article's findings, emphasizing the discovery of feathers in non-avian species like pterosaurs and ornithischians, with phrases such as 'direct evidence' and references to specific extinct groups. The tone is straightforward and supportive, indicating an appreciation for the fossil evidence’s significance but limited deeper analysis or controversy.

AgreementModerate agreement

Most discussions acknowledge the evidence presented in the publication, especially the mention of direct evidence of feathers on various prehistoric animals.

InterestModerate interest

Participants show mild curiosity by discussing the significance of feather evidence and its relation to the fossil record.

EngagementNeutral engagement

Comments are somewhat superficial, mainly confirming facts rather than deep analytical discussions.

ImpactModerate impact

The conversations highlight some recognition of the importance of feather evidence for understanding evolution, indicating moderate impact.

Abstract in brief

  • The study finds morphological and chemical evidence pointing to the preservation of eumelanin pigment in the feathers of the Early Cretaceous bird Gansus yumenensis, including structures identified as eumelanosomes.
  • Chemical analyses show distinct organic compounds, like carboxylic acids and ketone groups, in the dark feather areas, indicating that original melanin pigments have endured over time.
  • Overall, the evidence suggests that both the microscopic structures and chemical signatures of melanin are preserved in these ancient feathers, providing clues about their original coloration and the fossilization process.]

@Matt_M_Bennett @DAKKADAKKA1 There is direct evidence of feathers on literally dozens of non-avian Avemetatarsalians including pterosaurs and ornithischians. https://t.co/Mq0ecYX3aD
