Paratomistoma (meaning "next to or near

derived member of Tomistominae, related to the false gharial. It may have been a marine or coastal crocodilian.[2]

Below is a cladogram based morphological studies comparing skeletal features that shows Paratomistoma as a member of Tomistominae:[3]

Crocodylidae

Crocodylinae

Tomistominae

Xaymacachampsa

Megadontosuchus

Kentisuchus

Maroccosuchus

Dollosuchoides

Tomistoma cairense

Maomingosuchus

Tomistoma schlegelii False gharial

Gavialosuchus

Tomistoma lusitanicum

Paratomistoma

Tomistoma coppensi

Based on morphological studies of

gavialoids.[4] 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).[5][6][7][8][9][10][11]
