  <dc:description>&lt;p&gt;&lt;span&gt;The Devonian plant fossil&amp;nbsp;&lt;/span&gt;&lt;i&gt;Protosalvinia (Foerstia)&lt;/i&gt;&lt;span&gt;&amp;nbsp;has been examined by solid-state&amp;nbsp;&lt;/span&gt;&lt;sup&gt;13&lt;/sup&gt;&lt;span&gt;C nuclear magnetic resonance spectroscopy (NMR) and pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS). Results of these studies reveal that the chemical structure of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Protosalvinia&lt;/i&gt;&lt;span&gt;&amp;nbsp;is remarkably similar to that of coalified wood. A well-defined phenolic carbon peak in the NMR spectra and the appearance of phenol and alkylated phenols in pyrolysis products are clearly indicative of lignin-like compounds. These data represent significant new information on the chemical nature of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Protosalvinia&lt;/i&gt;&lt;span&gt;&amp;nbsp;and provide the first substantial organic geochemical evidence for land plant affinity.&amp;nbsp; Protosalvinia, Foerstia,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Upper Devonian, biostratigraphy, carbon-13 NMR, PY-GC-MS, lignin.&lt;/i&gt;&lt;/p&gt;</dc:description>
