Re: The terminal thumb phalanx of Orrorin tugenensis



Marc Verhaegen:
Certain of the anatomical characters classically associated with
manipulation and/or fabrication of tools are already present in the Late
Miocene
species Orrorin tugenensis as shown by the terminal thumb phalanx BAR
1901'
01. This specimen reveals crucial information suggesting that
thumb morphology is not exclusively related to such tool using and
manufacturing activities but reflects in a frequently bipedal creature a
deeper
adaptation concerning the precision grip essential for climbing and
balancing, different from that of apes.

Yes. Cliff hanging. Stone gripping. Climbing vertical surfaces.
Climbing sea cliffs.
Thanks, Marc. You have some paper, abstract?
