Trilobita - Phacopida - Encrinuridae
It was assigned to Phacopida by Sepkoski (2002); 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 variable width: length glabellae and equally variable outlines of lines joining tips of L2-L3- L4 lobes; glabellae with 50-90 tubercles, tubercle pairs symmetrical across (tr.) LI and L2, and rarely L3 lobes, in some species (lapworthi, rarus, and gelaisi n. sp.), without symmetry in the others; short anterior cranidial borders in dorsal view, with omnipresent tubercles; with short genal spines (except lapworthi) and hypostomata with elongated middle bodies (except rarus); pygidia with subequal width-length ratios, 17-21 axial rings, 7-9 pleural ribs, and 1-2.5 congruent pleural ribs and axial rings.|
|D. K. Moss and S. R. Westrop 2014||Strongly expanded, “mushroom-shaped“ glabella (character 1, state 1), strongly perforated, small tubercles in the 1L-1, 2L-1, and 3L-1 positions (character 9, state 2), and a relatively narrow pygidium whose length is greater than 90% of maximum width (character 23, state 2).|
