The oldest fossil record of a living true eel lineage (Protanguillidae, Anguilliformes) from Mexico reveals the gradual acquisition of modern eel traits

2025-09-07

Abstract excerpt

We present an integrative taxonomic study describing the first fossil representative of the family Protanguillidae from the Danian deposits near Palenque, Chiapas, Mexico. Osteological analysis and parsimony-based phylogenetic reconstruction using morphological characters support the designation of a new genus and species as a protanguillid by the presence of several features, including the autogenous premaxillae,...
