Cuticles matured after lipid extraction and hydrolysis did not show the presence of these alkane/alk-1-ene homologues providing direct experimental evidence that lipids incorporated from the cuticle were the source of the aliphatic polymer.

Differences in the relative distribution of molecular components indicate likely chemosystematic differences between different fossil groups.

Chemical analyses of the fossil leaves revealed the presence of a recalcitrant (non-hydrolysable) geopolymer comprised of benzene derivatives, lignin-derived components, pristenes and an aliphatic component; the latter consists partly of fatty acyl subunits rang

Plant cuticle is also preserved but it is obscured or distorted by diatom impressions. Molecular analysis of dicotyledonous angiosperm leaf from the Enspel deposit revealed the presence of polysacchar
