---|---|---|
N. A. Smith 2011 | Dorsal and ventral edges of the mancalline scar extending
into primary pneumotricipital fossa taper to a point as in Mancalla lucasi, rather than remaining parallel as in Mancalla californiensis and Mancalla cedrosensis (123:1; Fig. 5); mancalline scar extending into primary pneumotricipital fossa is an excavated pit as in Mancalla californiensis rather than raised in relief to the fl oor of the primary pneumotricipital fossa and the humeral shaft as in Mancalla cedrosensis and Mancalla lucasi (121:0); humerus shorter than other known Mancalla (Tables 2 and 3). |
