  <dc:description>&lt;div class="abstract-content"&gt;&lt;div class="abstract" data-abstract-type="normal"&gt;&lt;p&gt;Tremadocian onlap is recorded by the Tribes Hill Formation. The formation is a lower Lower Ordovician (upper conodont Fauna B Interval(?)-&lt;span class="italic"&gt;Rossodus manitouensis&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;Zone) depositional sequence that unconformably overlies the Upper Cambrian Little Falls Formation.&lt;/p&gt;&lt;p&gt;Depositional environments and stratigraphy indicate that the Tribes Hill was deposited on a wave-, not tide-, dominated shelf and that a uniform, “layer-cake” stratigraphy is present. The deepening-shoaling sequence of the Tribes Hill includes the: 1) Sprakers Member (new; peritidal carbonate and overlying tempestite limestone and shale); 2) Van Wie Member (new; subtidal shale and limestone); 3) Wolf Hollow Member (revised; massive carbonates with thrombolitic cap); and 4) Canyon Road Member (new; glauconitic limestone and overlying evaporitic dolostone). The shoaling half-cycle of the Tribes Hill is older than a shoaling event in western Newfoundland, and suggests epeirogenic factors in earliest Ordovician sea-level change in east Laurentia. Conodont and trilobite biofacies track lithofacies, and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Rossodus manitouensis&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;Zone conodonts and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Bellefontia&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;Biofacies trilobites appear in the distal, middle Tribes Hill Formation.&lt;/p&gt;&lt;p&gt;Twenty-four conodont species are illustrated.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Ansella&lt;/span&gt;?&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;protoserrata&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;new species,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Iapetognathus sprakersi&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;new species,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Leukorhinion ambonodes&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;new genus and species, and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="italic"&gt;Laurentoscandodus&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;new genus are described.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
