Chelmsford's answer to Mary Anning.
Thea has been very busy this week. she has made an exciting Discovery in admirals park. She was looking at rocks near the river and found this. Her dad contacted the Essex rock and mineral society to ask what is was. This was their reply:
'Lovely to see this. An exciting find! This is a sea urchin fossil. It is a Micraster, preserved as a fossil in flint. It is from the sea bed 80 million years ago when a sea covered most of England. The fossil got into the river after it was eroded from the rock that was left by an ice sheet less that half a million years ago. This rock is called till. It covers much of north Essex.'
How cool is this!
