| O.M. Kovalchuk et al. 2017 | However, Ch. pontica considerably differs from Ch. murchisoni (Figs. 3d–3f) in the following characters of the skull structure: (1) the skull is more expanded in the posterior part; (2) the cheek emargination is deepest in the anterior part; (3) the frontals are short and only slightly wedge in between the prefrontals; (4) the parietals are wide, expand significantly posteriorly. Taking into account these distinctions, the idea of synonymy of Ch. pontica and Ch. murchisoni looks baseless. |
