An extrapolation of the GPS data for South American data show that South America and Africa were joined between 87,000 and 2,000 years ago, the larger number being a linear extrapolation and the smaller a minimal exponential extrapolation. The extrapolation is based on insufficient data to be adamant about the time required for movement, but the methodology is the same as the extrapolation of the sea-floor spreading data used to arrive at the continental drift number.

I can't vouch for the source - or the detail - but if there's any further scientific info around that verifies this statement, I would love to hear about it.
Looks like 'they' might have WALKED to their destination?

Africa and South America split 120 million years ago. They have been moving apart at the same speed your fingernails grow ever since.
