The bedrock at Watchtree consists of siltstones from the Lias Group, sediments laid down at the very end of the Triassic period and beginning of the Jurrasic Period some 180 -205 Million years ago. These compacted silts and mudstones, types of sedimentary rock, are horizontally bedded and were laid down over a period of many thousands of years in a warm tropical sea.
Its likely that the more famous dinosaurs, such as Tyrannosaurus Rex and Diplodocus, arrived on the scene slightly later than When the siltstones were created at Watchtree.
How did siltstone created near the equator end up at Watchtree, now some six thousand miles away and nearer to the north pole than the equator?...
The position of the continents as we see them today is much different to how they appeared two hundred million years ago. Each continent has gradually split apart, by only a matter of centimetres each year to end up in the positions we see them today. Watchtree was once a part of a huge landmass called Pangea and was positioned somewhere near the equator 200 million years ago.
The continents are still moving today and the result of this movement can often be seen in the form of earthquakes and volcanoes due the huge amounts of energy involved.
