Opis:

Comparison of three djadochtatheriid skulls in lateral view, rendered to approximately the same length. The muscle scars surrounded by the anterior and intermediate zygomatic ridges are shaded. The details of the structure of the orbit have been omitted. A. Kryptobaatar dashzevegi Kielan−Jaworowska, 1969, based on photographs and reconstruction of the specimens from Ukhaa Tolgod, figured by Wible and Rougier (2000), and skulls from Bayan Zag housed in ZPAL. The vascular nasal foramina as preserved in the holotype ZPAL MgM−I/21. B. Djadochtatherium matthewi Simpson, 1925, tentative reconstruction based on: the holotype AMNH 20440 (rostral part of the skull and both dentaries from Bayan Zag); HMNS94−10−278 (fairly complete skull with incomplete dentaries from Tögrög, examined on the photographs); GI 5/301 (partial dentary from Ukhaa Tolgod); and the photograph of the complete skull with both dentaries from Ukhaa Tolgod, figured by Webster (1996, the number not available). C. Catopsbaatar catopsaloides (Kielan−Jaworowska, 1994), reconstruction of the skull in lateral view, based on all known specimens. Orbital wings of the lacrimal, not preserved in Djadochtatherium (B) and Catopsbaatar (C) have been reconstructed on the basis of comparisons with Kryptobaatar (A).
