A recent discovery of fossil wood related to the mangrove environment, increased to the evidence that these environments developed further south in South America during the late Miocene. The fossil is closest to the genera, Conocarpus and Laguncularia, with anatomical characteristics that are particularly similar to those of Conocarpus erectus. C. erectus is a species associated with mangroves and is classified as pseudo mangrove or peripheral species. Mangroveoxylon areniensis Moya & Brea (2020), recovered in the Late Miocene? of Ituzaingó Formation is the first record of fossil wood that indicates a coastal marine environment, which is further south of the tropics. This could resemble a tropical environment with species developing at different levels of the land.
