A Latest Sakmarian–Earliest Artinskian (i.e. Late Wolfcampian) fusulinid assemblage, mainly composed of Levenella (?) and Pseudofusulinoides, has been discovered in the Purulhá area, Guatemala. It contains some Tethyan species never described in America, mixed with more classical cratonic North American species. Palaeobiogeographically, this association allows improved correlations between the American and Tethyan faunistic provinces, and provide evidence of repetitive fusulinid and alga migrations during the Permian through Palaeopacifica, from the eastern Asian Blocks to the Chortis Block.
