Fossil snakes from the Palaeocene of São José de Itaboraí, Brazil Part III. Ungaliophiinae, Booids incertae sedis, and Caenophidia. Summary, update and discussion of the snake fauna from the localityJean-Claude RageKeywords: booid-grade incertae sedis; Brazil; Caenophidia; New taxa; Palaeocene; Russellophiidae; Snakes; tropidophiids; Ungaliophiinaedoi: 10.18563/pv.36.1-4.37-73 Abstract Aside from Madtsoiidae, anilioids, and Boidae that were studied previously, the middle Palaeocene of ltaborai (BraziI) has produced Ungaliophiinae ("tropidophiids"), booid-grade snakes incertae sedis, and a possible Russellophiidae (Caenophidia) that are described in the present article. This article is the third and final report on the snakes from the locality. The Ungaliophiinae (Paraungaliophis pricei gen. et sp. nov.) are rare whereas the booid-grade snakes incertae sedis (ltaboraiophis depressus gen. et sp. nov., Paulacoutophis perplexus gen. et sp. nov.) are more frequent. A single vertebra is referred to the Russellophiidae (Caenophidia) with reservation. An update of the whole fauna of snakes from ltaborai is provided. Hechtophis austrinus that was tentatively referred to the erycine Boidae is now regarded as a Boidae incertae sedis. Most snakes from Itaborai are known only from the locality. Astonishingly, only the ailioids Coniophis cf. C. precedens gives possible evidence of interchanges between South and North America. The fauna of snakes from Itaborai, as well as the other Palaeocene faunas of snakes from South America are distinct from those of the Cretaceous and the Eocene of South America; they appear to be more different from the Cretaceous faunas than from those of the Eocene. The fauna from Itaborai is the richest and most diverse assemblage of snakes from the Palaeocene worldwide; it shares only a few taxa with other Palaeocene localities.

Fossil snakes from the Palaeocene of Sao José de Itaborai, Brazil, Part II. BoidaeJean-Claude RageKeywords: Boidae; Boinae; Brazil; Erycinae; New taxa; Palaeocene; SnakesAbstract The middle Palaeocene of São José de ltaboraí (State of Rio de Janeiro, Brazil) has produced a rich and diverse fauna of boid snakes. It comprises six or seven species: Hechtophis austrinus gen. et sp. nov., Corallus priscus sp. nov., Waincophís pressulus sp. nov., Waincophis cameratus sp. nov.,"Boinae A", and "Boinae B". Moreover, two dentaries might pertain to either H. austrinus or "Boinae B", or even represent a distinct taxon. Hechtophis austrinus is assigned, with reservation, to the Erycinae. All other taxa are referred to the Boinae. The vertebrae of all taxa have paracotylar foramina, which raises the problem of the apomorphic or plesiomorphic nature of this feature. This fauna also raises the question of the presence of extinct erycine boids in South America, but it does not allow this question to be settled.
