  <dc:description>&lt;p&gt;Sequential morphologic changes in pollen of the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Momipites‐Caryapollenites&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;lineage from Paleocene strata in the Wind River Basin of Wyoming appear to reflect evolution within the family Juglandaceae. The stratigraphic occurrence of the species within this complex permits the establishment of six biostratigraphic zones that can be correlated between outcropping and subsurface sequences within the basin and to surrounding areas.&lt;/p&gt;&lt;p&gt;Trends involving changes in shape and size of the pollen and in structure of exine at the poles proceed from a basic form of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Momipites&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;to six other distinguishable species. The genus&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Caryapollenites&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;appears to have been derived from the basic form of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Momipites&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;by changes in size and development of heteropolarity in pore position.&lt;/p&gt;&lt;p&gt;Species of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Momipites&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;described as new are&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. wyomingensis, M. waltmanensis, M. ventifluminis, M. actinus, M. anellus,&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;M, leffingwellii.&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;The genus&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Caryapollenites&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;is redescribed and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. prodromus, C. imparalis, C. inelegans,&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. wodehousei&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;are described as new.&lt;/p&gt;</dc:description>
