Dollosuchus

and Evolution]]''. WH Freeman and Company, New York ISBN 0-7167-1822-7. 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.

Dollosuchus was originally described on the basis of numerous mandibular fragments found from the Early to Middle Eocene Bracklesham Beds in the United Kingdom. The material cannot be distinguished from other related longirostrine, or long-snouted, crocodilians. The type specimen, IRScNB 482, is currently housed in the Gand Museum in Belgium.

Species
The type species of Dollosuchus is D. dixoni. Many other species that once belonged to other genera have been proposed as members of the genus, but little work has been published to support these claims. Charactosuchus kugleri, another Eocene crocodilian, has been suggested to be synonymous with Dollosuchus, but this is no longer likely due to the fact that C. kugleri is now thought to be a member of the family Crocodylidae, and thus closer related to modern crocodiles than to gharials. It has been suggested that Kentisuchus spenceri, Megadontosuchus arduini, and Dollosuchus dixoni are all synonymous with one another. If this is the case, the name Dollosuchus would be adopted for all three genera, as the name has seniority over the other two. Despite this, the three taxa would remain their own distinct species.
