  <dc:description>&lt;div class="abstract-content"&gt;&lt;div class="abstract" data-abstract-type="text-abstract"&gt;&lt;p&gt;Davydov et al. (1995) recently proposed the Aidaralash Creek section in northern Kazakhstan (Figures 2 and 3) as the Global Stratotype Section and Point (GSSP) for the base of the Permian System. The proposed boundary is the level in an evolutionary sequence where&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Streptognathodus wabaunsensis&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;Gunnell gives rise to a descendent with an isolated node field on the inside of the upper platform surface. This morphotype constitutes a new and distinct species for which we propose the name&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Streptognathodus isolatus&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;new species.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
