(A,B), carapace plates corresponding to several individuals, in dorsal (A) and ventral (B) views: nuchal MNHN.F BR13461; neurals (anterior to posterior) MNHN.F BR13458, MNHN.F BR17487, MNHN.F BR13710, MNHN.F BR13459; right costals (anterior to posterior) MNHN.F BR13001, MNHN.F BR13620, MNHN.F BR2785, MNHN.F BR18001, MNHN.F BR13637, MNHN.F BR13628; left costals (anterior to posterior) MNHN.F BR13624, MNHN.F BR4188; right peripherals (anterior to posterior) MNHN.F BR13604, MNHN.F BR18000, MNHN.F BR13611, MNHN.F BR13468, MNHN.F BR15098, MNHN.F BR13610; left peripherals (anterior to posterior) MNHN.F BR13603, MNHN.F BR18002, MNHN.F BR13595, MNHN.F BR13465, MNHN.F BR13608, MNHN.F BR2758, MNHN.F BR4180, MNHN.F BR13480, MNHN.F BR13467. The anterior or posterior views of the peripherals are also shown in A. Scale bars equal 1 cm. For the identification of each element see Fig. 4A. (C,D), nuchal MNHN.F BR13669, in dorsal (C) and ventral (D) views. (E–H), visceral view of the the third (right) to the sixth (left) bridge peripherals MNHN.F BR13622, MNHN.F BR13623, MNHN.F BR18002 and MNHN.F BR18000. (I,J), details of the outer surface of the neural MNHN.F BR13459 (I) and costal MNHN.F BR13579 (J). Abbreviations for the plates (in lowercase and normal type): c, costal; n, neural; nu, nuchal; p, peripheral. Abbreviations for the scutes (in uppercase and in bold type): CE, cervical; M, marginal; PL, pleural; V, vertebral.
