Dollosuchus is an extinct genus of gavialid. It is a basal tomistomine closely related to Kentisuchus, according to several phylogenetic analyses that have been been conducted in recent years, and is the oldest known tomistomine to date. Fossils have been found from Belgium and the United Kingdom. It had large supratemporal fenestrae in relation to its orbits, similar to Kentisuchus and Thecachampsa.
