If australopiths ever lived in ‘savanna’ (as traditionally assumed), it was wet savanna: Reed 1997 JHE 32:289:
- Pliocene australopiths "existed in fairly wooded, well-watered regions",
- Pleistocene robust apiths existed ‘in similar environs & in more open regions, but always in habitats that include wetlands".

Some examples collected by Verhaegen & Puech 2000 Hum.Evol.15:175 (confirmed by all publications after 2000):
A.afarensis
-Johanson cs 1982: "Generally, the sediments represent lacustrine, lake margin & associated fluvial deposits related to an extensive lake that periodically filled the entire basin"
-Radosevich cs 1992: "The bones were found in swale-like features … very likely they died & partially rotted at or very near this site … this group of hominids was buried in streamside gallery woodland"
-Johanson & Taieb 1976 on Lucy: "Fossil preservation at this locality is excellent, remains of delicate items such as crocodile & turtle eggs & crab claws being found"

A.boisei
-Conroy 1990: "The lake margins were generally swampy, with extensive areas of mudflats … swamp vegetation is indicated by abundant vertical roots channels & casts possibly made by some kind of reed. Fossil rhizomes of papyrus also suggest the presence of marshland & shallow water"
-Carney cs 1971 on Baringo: "The fossiliferous sediments were deposited in a lagoon … Abundant root casts suggest that the embayment was flanked by reeds, and the presence of calcareous algae indicates that the lagoon was warm & shallow. Bellamya & catfish are animals tolerant of rel.stagnant water, and such situation would also be suitable for turtles & crocodiles"
