This 10 million-year-old fossil is of an ape capable of bipedal locomotion, discovered in Europe and unlike any known linage of ape from Africa.

>>Rudapithecus was pretty ape-like and probably moved among branches like apes do now — holding its body upright and climbing with its arms. However, it would have differed from modern great apes by having a more flexible lower back, which would mean when Rudapithecus came down to the ground, it might have had the ability to stand upright more like humans do.

This evidence supports the idea that rather than asking why human ancestors stood up from all fours, perhaps we should be asking why our ancestors never dropped down on all fours in the first place.”<<

Fossils are interesting in that they don’t give us the full picture of the evolution of life.
I imagine numerous flora/fauna was never fossilised so we have no record of it existing
