Beautiful Fossil plant Alethopteris grandini The rocks, minerals and fossils we find all around us help us to understand the geological history of the Earth from its origins around 4,600 million years ago, and the processes involved in forming and shaping the earth's crust. In particular, our collections provide evidence for how the Wales we know today has evolved over 700 million years. These specimens record how Wales has drifted from the southern hemisphere to its present-day setting 52° north of the equator. สนใจติดต่อ ศิริพงศ์ โทร 089-1411002
