Fig. 11. Structure of the carpus of Mesosaurus tenuidens Gervais, 1865, in presumed subadult and adult specimens from Iratí Formation, Paraná, Brazil,? lower Permian (A–C) and Griquas region of southern Africa,?lower Permian (D). A, B. Manus of sub-adult SMF-R 4492 (A) and young adult SMF-R 4528 (B). In B five bones can be seen in the proximal carpal series, including a small ossified radiale close to the lateral centrale. Four bones (and perhaps an incipiently ossified very small dc5) are preserved in the distal series. C. Manus of SMF-R 4710, right (C1, C2) and left (C3, C4), a more mature specimen, →
