Anurans of In Becetèn (Republic of Niger): the most diverse site for amphibians in Mesozoic Africa

Geodiversitas 48 (4): 51-67, DOI: 10.5252/geodiversitas2026v48a4 ABSTRACT In Becetèn (Niger) represents one of the most diverse continental vertebrate faunas from the Late Cretaceous of Africa.

Recently, anurans, in particular aquatic pipimorphs, have generated renewed interest, with the identification of four distinct pipimorph taxa. Here we describe the remaining anuran specimens from In Becetèn, which represent at least three new anuran taxa that cannot be assigned to pipimorphs (Anura indet, Neobatrachia and a ranoid). Among them, one taxon, documented by ornamented cranial material, is a large Neobatrachia incertae sedis, as suggested by our phylogenetic analyses.
