was awesome to realise that these deposits would take us back
far into the Ice Age and would probably contain clues about
how the natural world around Creswell had changed. Would you
believe there is even well preserved pollen from the Ice Age.
The rest of the plants have long since rotted away but, when
the palaeobotanist came to take samples through the whole
section, he told us that he could wash out the pollen grains
then identify what plants they came from by looking at them
through a microscope. He will be doing this and counting the
grains of each type of plant in every layer. Then he will
be able to say what the vegetation was like and how it changed
as the climate got warmer or colder. Next |
