#autochthonous

• Autochthonous — Being native to the same region or country where it lives, develops, or manifests; having formed and evolved historically on the territory where it is currently found, without having migrated, been introduced, or colonized from the outside. In biology, it describes plant or animal species native to a specific structural ecosystem, whereas in anthropology it refers to ancient indigenous populations.
• Autochthonous — Formed, developed, and living within the very territory where it is currently found; specific or originating from a certain geographic region, without being introduced from the outside via migration or colonization. Broadly, the term describes populations, traditions, floral or faunal species, and cultural values that constitute the primordial historical or ecological foundation of a space.
• Bafflestone texture — A type of autochthonous carbonate sedimentary rock (limestone), according to the revised Dunham classification (Embry and Klovan), where the original organic components (such as fan-shaped corals or calcareous algae) grew together during deposition, acting as baffles that slowed down water flow and trapped fine sediment.
