If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|R. Iannuzzi and H. W. Pfefferkorn 2002||D. gothanica is distinguished from D. bodenbenderi by pinnules that tend to be straighter, wedge-shaped, with terminal lobes that tend to be undivided or rarely slightly lobed. Pinnules and pinna axes are always inserted at acute angles in a three-dimensional branching pattern.|
