DOI:
doi:10.5061/dryad.mp48001
摘要:
Fossils are the only remaining evidence of the majority of species that have ever existed, providing a direct window into events
Data from: Assessment of available anatomical characters for linking living mammals to fossil taxa in phylogenetic analyses

DOI:
doi:10.5061/dryad.0t67n
摘要:
Exceptional fossils can preserve diagenetically-altered biomolecules, and understanding the pathways to such preservation is vital to utilisi

DOI:
doi:10.5061/dryad.qq106tm4
摘要:
calibration data can be obtained from macro- and mesofossils (e.g., leaves, flowers, and fruits) or microfossils (e.g., pollen). Fossil data can vary subst
