Article Synopsis
- - Fossils were previously thought to be devoid of original organic molecules, but recent analyses have shown that some, like dinosaur bones, can preserve components such as collagen and blood vessels, although these materials are susceptible to degradation.
- - Fresh excavations and careful analyses suggested that what was considered 'soft tissues' in dinosaur bones are likely biofilms rather than intact original proteins and lipids, due to their chemical and structural differences from true collagen.
- - The study found that dinosaur bones host a diverse microbial community, distinct from the sediments around them, indicating that these bones provide a nutrient-rich environment for microbes, which complicates the identification of original organic materials and suggests potential roles for microorganisms in fossil preservation.
