We compared structural biopolymers from morphologically well-preserved Metasequoia tissues from three Tertiary deposits and detected a continuum of biochemical preservation seen in this evolutionarily conserved conifer. Pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) was applied to solvent...
