A Very Old Rock!!!!!

Since we have been looking at rocks in Science, Lillie brought in a very interesting old rock to look at, her Grandad found it 30 years ago in a river. He took it to the Leeds Museum to be dated and he found out it was 290 million years old, yes I haven't got it wrong, it really was 290 million years old!!!!!!!!!!!!!!I found it totally amazing and interesting and could not believe I had held something so old, the rest of Year 3 found it amazing too. Below are some pictures of the rock and a copy of the wording that was written in the museum analysis.
The Museum Analysis;
Found; 25th March 1981
In a stream on a farm
This is the root of a tree fern which lived during the Coal Measure Times, in the Carboniferous period about 290 million years ago. It is called STIGMARIA FICOIDES. The small pits on the surface are where rootlets where attached to the main root. You can also see the vascular bundle at the centre of the main root.
