. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. Fig. 4.—Micranteosaurus parvus Gen. et Sp. Nov. 4323, Commonage, Merweville, Beaufort - West District. Semi-diagrammatic restoration of right manus seen in dorsal view x plus-minus \. C.— centrale; I—intermedium; Re— radiale; Ue—ulnare. As a whole the carpus is very Pelycosaur-like, approaching that of Ophiacodon fairly closely, except that there is only one centrale. The metacarpals are somewhat dorso-ventrally flattened bones in general rod-like with slightly constricted waists; the decrease in size from the first to the fourth is fairly evenly graded, but the fifth is much reduced; the first metacarpal is distinguished by being much broader than the others and thus relatively more flattened with expanded ends. In the first digit the first phalanx is broad proximally, with a waist situated in the anterior half; the distal end is much narrower than the proximal; the second phalanx is much smaller, also broader proximally than distally, with the waist nearly in the middle; anterior to the second roughly hourglass-shaped phalanx there is preserved the proximal end of the ungual phalanx, so that in the first digit there are 3 segments. This is most unusual, but there is no doubt that such is the case. Even without the preserved proximal end of the ungual phalanx the count would also be 3, for the second phalanx with its hourglass-shape could not possibly be an ungual Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
