Comparison of humeri in two Triassic ichthyopterygians. (a–d) Right humerus of Cymbospondylus youngorum LACM DI 157871 in (a) ventral, (b) anterior, (c) proximal, and (d) distal views. (e–h) Ichthyopterygia gen. et sp. indet. NSM PV 24995 in (e) ventral, (b) anterior, (c) proximal, and (d) distal views. Bone contour (thick solid lines), boundary between periosteal and endosteal bones (thin solid lines) and distinct ridges (broken lines) are indicated. Scale bars equal 20 cm in (a–d) and 50 mm in (e–h). afd distal part of anterior flange, afp proximal part of anterior flange, dpc deltopectoral crest, pdt postero-distal tuberosity.
