Abstract:
... Cuticles of compression-preserved Dicroidium odontopteroides and Johnstonia coriacea (Corystospermaceae, Upper Triassic, Mendoza, Argentina) are spectrochemically analyzed. The objectives included (i) studying the chemical resistance of cuticles to different oxidative conditions to gain new insights into their fine molecular structure and its likely (ii) chemotaxonomical and (iii) paleoecophysiolo ...
