Reports of preserved cells & other soft tissues in ancient vertebrates (eg dinosaurs) have been met with controversy within the field of vertebrate palaeontology. Schweitzer hypothesized that iron-mediated radical crosslinking preserves ancient soft tissues

Despite an extensive published literature, skepticism over the claim of original biochemicals including proteins preserved in the fossil record persists...

Dinosaur soft tissues are shown to be remarkably preserved to the sub-micron level of ultrastructure despite environmental and biological factors associated with burial...

Mounting evidence from dinosaur bones shows that, contrary to common belief, organic materials can sometimes survive in fossils for 'millions of years'... or can they?

Claims of extreme survival of DNA have emphasized the need for reliable models of DNA degradation through time. By analysing mitochondrial DNA (mtDNA) from 158 radiocarbon-dated bones...
