腭部和颚部结构是研究鳄形类进化的重要结构。Notosuchians，sebecosuchians和其他Mesoeucrocodylia显示出相当大的多样性模式。一些背鳄类（马里利亚鳄属、背鳄属、泥炭鳄属）与至少一种扁鳄类（层鳄属）具有重要的相似性，特别是三角形-近三角形的鳍骨，以及从眶下窗的后缘排除翼骨。这些特征的使用可能代表系统发育分析中的有用信息，并且应该总是详细描述。
The palate and choanae structures are important to the study of the evolution in Crocodylomorpha. Notosuchians, sebecosuchians and other Mesoeucrocodylia show a considerable diversity of patterns. Some notosuchians (Mariliasuchus, Notosuchus, Sphagesaurus) possess important similarities with at least one sebecosuchian (Stratiotosuchus), especially the triangular-subtriangular choanae, and the exclusion of the pterygoid from the posterior border of the suborbital fenestra. The use of these characteristics may represent useful information in phylogenetic analysis and should always be described in detail.
