AI synopsis

What people are saying

The discussion highlights interest in the scientific rigor behind the findings, with comments questioning the exclusion of bacterial contamination and suggesting simpler tests like C14 comparisons. The tone is cautious but engaged, emphasizing technical details and the need for additional verification, which reflects a moderate impact on how the community perceives the research's significance.

AgreementNeither agree nor disagree

The discussion shows some skepticism about the interpretation of spectral and PCR results, but no strong disagreement with the overall findings.

InterestModerate interest

Participants are somewhat interested, particularly in the methods used to exclude contamination and confirm biomolecule preservation.

EngagementModerate engagement

Comments reflect a basic level of engagement, questioning some methods and advocating for more thorough testing.

ImpactNeutral impact

The discussion suggests that the article's findings are noteworthy but not considered definitively groundbreaking or transformative at this point.

Abstract in brief

  • Research indicates the presence of collagen in dinosaur fossils through mass spectrometry, but direct spectroscopy on isolated tissues hasn't been done until now.
  • A study on a humerus from a Late Cretaceous mosasaur shows retained protein molecules, with immunofluorescence revealing reactivity to type I collagen antibodies and amino acid analysis suggesting structural proteins.
  • Synchrotron infrared microspectroscopy confirms these proteins are located in bone matrix fibrils typical of collagen, distinguishing them from potential contaminants, thus suggesting biomolecular preservation in various skeletal elements beyond just large bones.

@MyChristianfam1 https://t.co/S30n6uxZEE they had weak explanation but its contradicted by spectral analysis and DNA PCR results. I wrote them with easy way to exclude bacteria and they blew me off. Simple as testing outer and inner parts of bone, if same c14 = endogenous https://t.co/RrOXdxsyxu https://t.co/sgUcEUbGbL
