  <dc:description>&lt;p&gt;&lt;span id="_mce_caret" data-mce-bogus="1" data-mce-type="format-caret"&gt;&lt;span&gt;Four Paleozoic bivalved genera are assigned to the new molluscan class Rostroconchia:&amp;nbsp;&lt;/span&gt;&lt;i&gt;Eopteria, Euchasma, Conocardium&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Pseudoconocardium&lt;/i&gt;&lt;span&gt;. These mollusks have an uncoiled univalved larval shell; an untorted bivalved adult shell; no hinge teeth, ligament, or adductor muscles; and a fused, almost inflexible. hinge. Rostroconchians developed separately from the pelecypods through the ribeirioids, but are regarded as more closely related to the Pelecypoda and Scaphopoda than to other known classes of mollusks.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;</dc:description>
