The Culebra Formation (Tcb)Geologic Map, 1980 is a geologic formation in Panama. It preserves fossils dating back to the Miocene period; Early Miocene epoch, Aquitanian to Burdigalian stages (Late Arikareean to Hemingfordian in the NALMA classification).Culebra Formation at Fossilworks.org Fossils of Culebrasuchus have been found in and named after the formation.Culebrasuchus at Fossilworks.org The thickness of the formation is at least thick,Kirby et al., 2008, p.7 and the age has been estimated as from 23 to 19 Ma.Kirby et al., 2008, p.11
