  • Professor Iain Stewart draws a map in the sand to introduce a puzzle which challenged early Scottish geologists. 500 million years ago trilobites swam in warm shallow waters and their fossils are found around Scotland. These fossils are the same as those found in North America, but different from those found in England and continental Europe. Stewart poses the question of why there is this difference.

Ideas for use in class
  • Show this clip and have students discuss possible answers to the question before showing the the answer in part two of the clip 12931, which shows collision between England and Scotland. This gives a useful demonstration of comparative timescales between geological processes and life on earth. Can also be used with other extracts from 'Men of Rock' series to understand how comparatively recent many geological theories are.
