Calanguban is an extinct genus of scincomorph lizard from the Early Cretaceous of South America. The type species Calanguban alamoi was named in 2014 from the Crato Formation of Brazil and is the oldest known non-iguanian lizard from the continent. It likely had an arboreal lifestyle.[1] The holotype (MN 7234-V) was destroyed in 2018 due to the National Museum of Brazil fire, so a neotype (MN 7875-V) possibly from the same formation was proposed in 2025.[2]
