While walking the dogs today in warncliff woods down near outibridge I found lots of fossils of seashells in slate. Does that mean at one time Sheffield must have been beneath the sea, would that have been before the ice age.:confused:

Yes of course.
Don't forget that the earth's crust slowly moves and goes up and down over millennia. And the pieces you saw may have been laid down billions of years ago hundreds of feet below sea level.

Its really fantastic when you think about it when these shells were alive man possibly wasn't even around.:)

Even the high peaks in Castleton were once under a shallow sea. You'll find lots of fossils in the limestone there. I took my daughter to Blue John caverns in the summer and was pointing out the fossils in the cavern walls to her. Mind boggling to think that Britain was once on the equator as well.

We have a family cottage on Gorgian Bay ,which is part of the great lakes system in Canada.
All along the shore are fossils from the Devonian period which is 300,000,000 years ago(give or take a few million years)

Under the clay soil on the allotments on the hillside alongside of the Hagg Hill there is the fossil remains of tropical tree forest

These are very much like palm trees which were growing there millions of years ago.

Whatever happened to the fossilised tree remains that were once in the grounds of the South Yorkshire Asylum Grounds.

Are they still there after all the redevelopment of the site?

Happy Days!

The ones at Middlewood are still there. During the building work the Museum and a team of volunteers uncovered a total of 13 stumps. After examination and taking some casts, they were re-buried to protect them, but the site is to be transferred to the City Council in 2005/2006, and it's intended to display a cast of the best one there, with access and signage for the public. There's to be a cast in the refurbished Museum too.

seen loads of fossilised palm fronds in the coal when i worked down ncb orgreve in the late sixties
