FIGURE 1. Linear measurements used for morphological comparison. B-L - buccolingual width; upper teeth - posterior-most tip of the metastyle to the lingual margin of the protocone; lower teeth - lingual-most tip of the metaconid to the buccal margin of the talonid. A-P - anteroposterior length; upper teeth - posterior-most tip of the metastyle to the anterior-most tip of the parastyle; lower teeth - anterior tip of the trigonid (paraconid) to the posterior end of the talonid (entostylid). TRI - width of the trigonid. TAL - width of the taloned basin. HL - total humerus length; proximal-most tip of greater tuberosity to distal-most point on capitulum. PW - width of the proximal end of the humerus: lateral most extent of the lesser tuberosity to the medial most aspect of the greater tuberosity. GT - length of the greater tuberosity. LT - length of the lesser tuberosity. DW - width of the distal end of the humerus: lateral most extent (entepicondylar process) to the medial most extent (ectepicondylar process). RL - total radius length: proximal-most tip of capitular process to distal-most tip of lunar articular facet. DL - length of the diaphysis. UF - length of the lunar articular facet. TUL - total ulna length; proximal-most tip of olecranon process to distal-most tip of terminal process. UL - ulna length without the olecranon fossa. Elements not to scale.
