I got a reply from Senior Curator: Palaeontology at museum of Wales: editted to fit:
Carboniferous Limestone was correct... The fossils are corals. You can see the gridwork of the calcium carbonate 'skeleton' of the corals.. these look like several solitary corals...yours looks most like Caninia.

I am informed by a Paleontologist that based on the location found "it's probably carboniferous limestone. The fossils look like (but closer inspection is required) coral and possibly the tops of crinoids". But a botanist believes the leafy structures look like juvenile clubmoss. So... Dunno.

Swampy/wet forest area near Creigiau, Wales.

Sorry, not a geologist, just spotted it and noticed the linear pattern and picked it up. And noticed more and more detail as I turned it over.

Scary Santa is an old sepia tome photo from the 1950s. His eyes stare through your very soul and his hand is the size of a child's head.

This family photo has been in the album since I was born and is of my mom aged 5... It still gives me nightmares... "He knows when you are sleeping... he knows when you're awake..."

"Adversarial poetry" anyone?

The once was an AI in the cloud.
The makers were all very proud.
When asked for illumination,
It often gave a hallucination,
But the answers were still used by the crowd.

"Beware the barrenness of a busy life" - Socrates

I am reminded of this wisdom as I sit reading the paper with a cup of coffee and contemplating the day before it runs away with itself and it becomes tomorrow.

A photo from inside the witches tower near pontyclun. Looking upwards, the optical illusion is one of being in the bottom of a well.
