Some people from the Gatton Lapidary Club had set up a stall at our local markets today.
I couldn't resist making a few purchases.
This particular slice is a big as your hand out stretched and 5 or 6mm thick.
It's chock full of fossilized sea creatures.:eyepop:
Here's some examples.

I pushed the contrast in the images to make them stand out more.

Very cool fossilised rock.
Reminds me of Inca art as seen from the air.
Imagine how much of this type of fossil record has disappeared due to techtonic plate movement.:thumbsup:

When you think about how old this rock must be to contain such primitive critters, it just blows my mind.
I must do a search and find out what they actually are.

Hi JJJ, they look like they may be Crinoids which were quite abundant on the sea beds millions of years ago.

Nice items Jeanette - but, as we all know - nothing is older than 4,000-odd years :whistle:

It does, it is life after death in a way.

To be flippant now, just think, 10000 years from now, they will dig up a rock and find.......ME :P

(Sorry)

Cheers

There's a similar rock thats found on the east coast of Scotland. It known as Dunbar Marble. Unfortunately most of it ends up in the kilns of the cement works. Looks great polished like yours Jeanette. Thanks for the pics.
Couldn't find a link to the polished specimens, but here's one to the location.

Bill,
Unfortunately mine isn't polished. Just very wet.
I thought it might make a nice feature in the fish tank actually.

Mr Chris,
:lol: Yeah sure, and there were Dinosaurs on the Ark too.:lol:
