La Colonia
Description
Source: Wikipédia
The La Colonia Formation is a geological formation in Argentina whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
Originally thought to be Campanian (c.73-72 million years ago) in age or earlier, studies of underlying formations have made a Maastrichtian (72–66 million years ago) age more likely. A further study in 2021 utilizing magnetostratigraphy and palynological data provided an age of 69 to 64 million years ago.
