Eocene reptiles of Africa

Gigantophis is an extinct genus of giant snake containing a single species, G. garstini. Before the Paleocene constrictor genus Titanoboa was described from Colombia in 2009, G. garstini was regarded as the largest snake ever recorded. It lived about 40 million years ago during the Eocene epoch of the Paleogene Period, in the Paratethys Sea, within the northern Sahara, where Egypt and Algeria are now located.

The type species, Coniophis precedes, was about 7 cm long and had snake-like teeth and body form, with a skull and a largely lizard-like bone structure. It probably ate small vertebrates, such as lizards and salamanders. The fossil remains of Coniophis were first discovered at the end of the 19th century in the Lance Formation of the US state of Wyoming, and were described in 1892 by Othniel Charles Marsh. For the genus Coniophis, a number of other species

Eogavialis is an extinct genus of eusuchian crocodylomorph, usually regarded as a gavialoid crocodylian. It superficially resembles Tomistoma schlegelii, the extant false gharial, and consequently material from the genus was originally referred to Tomistoma. Indeed, it was not until 1982 that the name Eogavialis was constructed after it was realised that the specimens were from a more basal form.
