Maroccosuchus zennaroi is an extinct gavialoid crocodylian from the Early Eocene of Morocco, traditionally regarded as a member of the subfamily Tomistominae. [2] [3]

Below is a cladogram based on morphological studies comparing skeletal features that shows Maroccosuchus as a member of Tomistominae, related to the false gharial: [4]

Crocodylidae

Based on morphological studies of extinct taxa, the tomistomines were long thought to be classified as crocodiles and not closely related to gavialoids. [5] However, recent molecular studies using DNA sequencing have consistently indicated that the false gharial (Tomistoma) (and by inference other related extinct forms in Tomistominae) actually belong to Gavialoidea (and Gavialidae). [6] [7] [8] [9] [10] [11] [12]

Below is a cladogram from a 2018 tip dating study by Lee & Yates simultaneously using morphological, molecular ( DNA sequencing), and stratigraphic ( fossil age) data that shows Maroccosuchus as an early-diverging gavialoid, more basal than the last common ancestor to both the gharial and the false gharial: [11]
