Transmission micro-FTIR spectroscopy has been conducted to elucidate the macromolecular structure of well-preserved fossil palynomorphs including prasinophycean algae, megaspores, chitinozoans, and scolecodonts. Plant and arthropod cuticles which may be present in palynological residues have also been investigated. Important differences are noted among these palynomorph groups regarding the intensities of CHx, Cdouble bond; length as m-dashO and aromatic Cdouble bond; length as m-dashC absorptions. Tasmanites, Leiosphaeridia, and plant cuticles are characterized by stronger aliphatic CHx stretching (3000–2800 cm− 1), strong CH3 (1460–1450 cm− 1), and intense Cdouble bond; length as m-dashO group (1710–1700 cm− 1) absorptions. Aromatic Cdoub...
