Trilobita - Phacopida - Encrinuridae
It was assigned to Phacopida by Sepkoski (2002); to Encrinuridae by Jell and Adrain (2003); and to Encrinurinae by Lespérance and Desbiens (1995) and Moss and Westrop (2014).
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.
|P. J. Lespérance and D. Desbiens 1995||Encrinurines with subequal width: length glabellae and broader than long pygidia, variable tubercle size indices (6-15), significant genal spines, round middle hypostomal bodies with shallow rhynchos, 14-25 axial pygidial rings, 6-9 pleural ribs, and 1-3 congruent pleural ribs and axial rings.|
|D. K. Moss and S. R. Westrop 2014||Librigena with precranidial lobe barely differentiated from anterior cephalic border, and with mostly granulose sculpture; anterior furrow obsolete (Fig. 6.8) or expressed only as reduction in density of sculpture (Fig. 6.5).|
