Ardipithecus
Reconstructed frontal view of the skeleton of “Ardi,” a specimen belonging to the early hominid species Ardipithecus ramidus.
To reconstruct the habitat of Ardipithecus ramidus at Aramis, scientists analyzed several types of fossilized botanical remains found in direct association with the hominin fossils. These plant fossils included:
- Wood: Provided direct evidence of the vegetation present in the environment.1
- Pollen: Helped researchers identify the types of flora that characterized the landscape.1
- Phytoliths: These microscopic silica particles, which form within plant tissues, offered further insight into the specific plant life of the region.1
By combining these botanical findings with data from soil isotopes, researchers determined that the environment 4.4 million years ago was a woodland habitat, rather than a tropical forest or an open grassland savanna. This woodland setting supported a diverse array of fauna, including forest-dwelling species such as porcupines and peafowl, and provided the resources for Ardipithecus to exist as a woodland omnivore.1
