Fig. 1 in Taxonomic implications of morphometric analysis of earless seal limb bones

Fig. 1. Measurements of the earless seal humerus (A) and femur (B) used in morphometric analysis exemplified by Erignathus barbatus (USNM 16116). In anterior (A1, B2), posterior (A2, B1), medial (A3), and proximal (A4) views. Abbreviations: DCF, distance between condyles; DDDC, diameter of diaphysis at deltopectoral crest; DN, diameter of the neck of the femur; GAP, distance between head of humerus and deltopectoral crest; HHF, height of the head of the femur; HHH, height of head of humerus; HPS, height of the patellar surface; HTL, height of capitulum; HTS, height of trochlea; ITW, intertrochlear width of the femur; LDC, length of deltopectoral crest; LGTF, length of the greater trochanter; LLF, length of the lateral side of the femur; LLCF, length of the lateral condyle; LMCF, length of the medial condyle; MLF, length of the femur on the medial side; PIT, depth of coronoid fossa; SUP, length of supinator ridge; TLH, total length of humerus; WCF, width across condyles; WDC, width of deltopectoral crest; WDEF, maximum width of distal diaphysis; WDEH, maximum width of distal epiphysis; WDF, minimum width of diaphysis; WDH, minimum width of diaphysis; WHH, width of humeral head; WLCF, width of lateral condyle; WMCF, width of medial condyle; WPDH, width of proximal epiphysis, humeral head to lesser tubercle; WPEF, maximum width of proximal diaphysis; WTA, width of trochlea in anterior view; WTD, width of trochlea and capitulum in posterior view.
