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.

Diagnosis
ReferenceDiagnosis
N. A. Smith 2011Mancallinae is diff erentiated from all other alcids on the basis of the following
unambiguously optimized humeral apomorphies: deltopectoral crest extends past the
midway point of the humeral shaft rather than restricted to the proximal half of the
humeral shaft (104:2); presence of a ‘mancalline muscle scar’ extending distally from
the primary pneumotricipital fossa (discussed below; 120:1); capital groove communicates
with transverse ligament sulcus resulting a notched rather than rounded appearance
of ventral margin of the humeral head in anterior view (136:2); humeral head
rotated anterodorsally rather than in-line with humeral shaft (139:1); humeral shaft
arced rather than sigmoidal (140:1); presence of fossae in tricipital sulci (150:1); anterior
surface of the ventral condyle rounded rather than fl attened (153:0). Additional
proposed apomorphies of Mancallinae include distal elongation (184:1) and anterior
fl attening of the fi rst metacarpal (185:1). Th ese characteristics are present in Mancalla
cedrosensis Howard, 1971, Miomancalla howardi sp. n., and two additional associated
specimens referable to Mancallinae (SDSNH 77966 and LACM 107028). Although
these two characters are also diagnostic for Alcini Storer, 1960, the clade composed of
Alca, Pinguinus, Alle Link, 1806, and Uria Brisson, 1760, the degree of distal elongation
and anterior fl attening in Mancalla exceeds that observed in Alcini.
