  <dc:description>&lt;p&gt;&lt;span&gt;Two new species of washakiin omomyids occur in deposits of early Bridgerian age.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Shoshonius bowni&lt;/i&gt;&lt;span&gt;, sp. nov., from the Aycross Formation, Absaroka Range, Wyoming, differs from&amp;nbsp;&lt;/span&gt;&lt;i&gt;S. cooperi&lt;/i&gt;&lt;span&gt;&amp;nbsp;in having enlarged conules on the upper molars and a second metaconule, features convergent with&amp;nbsp;&lt;/span&gt;&lt;i&gt;Washakius insignis. Washakius izetti&lt;/i&gt;&lt;span&gt;, sp. nov., from the Green River Formation, Piceance Creek Basin, Colorado, is the most primitive known species of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Washakius&lt;/i&gt;&lt;span&gt;, showing incipient development of features present in the later&amp;nbsp;&lt;/span&gt;&lt;i&gt;W. insignis&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;W. woodringi. Washakius&lt;/i&gt;&lt;span&gt;, cf.&amp;nbsp;&lt;/span&gt;&lt;i&gt;W. izetti&lt;/i&gt;&lt;span&gt;&amp;nbsp;occurs in the early Bridgerian of the Huerfano Basin.&amp;nbsp;&lt;/span&gt;&lt;i&gt;W. izetti&lt;/i&gt;&lt;span&gt;&amp;nbsp;is closely related to&amp;nbsp;&lt;/span&gt;&lt;i&gt;Utahia kayi&lt;/i&gt;&lt;span&gt;, a. washakiin possibly related to&amp;nbsp;&lt;/span&gt;&lt;i&gt;Stockia. Hemiacodon&lt;/i&gt;&lt;span&gt;, sometimes included in the Washakiini, is probably more closely related to the Omomyini.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Stockia&lt;/i&gt;&lt;span&gt;&amp;nbsp;is distinct from&amp;nbsp;&lt;/span&gt;&lt;i&gt;Omomys&lt;/i&gt;&lt;span&gt;&amp;nbsp;and is questionably included in the Washakiini, of which&amp;nbsp;&lt;/span&gt;&lt;i&gt;Loveina&lt;/i&gt;&lt;span&gt;&amp;nbsp;is the stem taxon. More advanced washakiins form two groups between which there was significant parallel evolution in dental morphology. One group includes&amp;nbsp;&lt;/span&gt;&lt;i&gt;Washakius, Dyseolemur, Utahia&lt;/i&gt;&lt;span&gt;, and possibly&amp;nbsp;&lt;/span&gt;&lt;i&gt;Stockia&lt;/i&gt;&lt;span&gt;, and is characterized by development of an open talonid notch before the consistent appearance of metastylids. The other group consists of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Shoshonius&lt;/i&gt;&lt;span&gt;, where the establishment of metastylids preceded the full opening of the talonid basins.&lt;/span&gt;&lt;/p&gt;</dc:description>
