Paleogene reptiles of Africa

Palaeophis ('ancient snake') is an extinct genus of marine snake that is the type genus of the extinct snake family Palaeophiidae.

Phosphatosaurus is an extinct genus of dyrosaurid crocodylomorph. It existed during the early Eocene, with fossils having been found from North Africa in Tunisia and Mali. Named in 1955, Phosphatosaurus is a monotypic genus; the type species is P. gavialoides. A specimen has been discovered from Niger, but it cannot be classified at the species level.

Congosaurus is an extinct genus of dyrosaurid mesoeucrocodylian. Fossils have been found from Lândana, in Angola and date back to the Paleocene epoch. In 1952 and 1964 Congosaurus was proposed to be synonymous with Dyrosaurus. The genus was later thought synonymous with Hyposaurus in 1976 and 1980. It has since been proven a distinct genus of dyrosaurid separate from both Dyrosaurus and Hyposaurus.

Eremosuchus is an extinct genus of sebecosuchian notosuchian from the Early Eocene El Kohol Formation of Algeria. It was first described on the basis of isolated cranial and postcranial material in 1989, although much of the original collection has since been lost. Like other sebecids it had serrated, blade-like teeth, a condition referred to as ziphodonty. Phylogenetic analysis conducted using Eremosuchus material yield inconclusive results, but overall support a close relationship with the terrestrial members of Sebecidae best known from the Cenozoic of South America, although also well esta
