Welcome to the Rock Gallery.

You will find here an expression of my wonder at the geological world – my fascination with stones and the stories they tell. From cliffs of dolerite through sea-ground jasper to specks of sapphires, it’s all amazing. My chief delight is in fossils, especially petrified wood and fern, and opal of all varieties. I can go all gooey over a good specimen of any of these!

Posts will be sporadic and may often consist of a photo and brief explanation.

Rocks are like stories are like people.

These are the stones containing the fossilised remains of a plesiosaur. Dad and the family slowly put it together from finds collected from hours of scouring a particular site on his station in northern Qld. He donated them to Kronosaurus Korner in Richmond where this photo was taken. It is a grand place to visit if you at all interested in the fossils of the Eromanga Sea which covered that area millions of years ago.

in a gully, we discovered what seems to have been a wash pool of some sort, because there was an eclectic collection of fossils, all disconnected, in a high concentration of copralite (yep, dino-dung!) The palaeontologist from the Kronosaurus Korner in Richmond (QLD) came out and helped us out with our understanding. Not many fossils were large enough to be photographed on the camera I had.

This is the wash pool. Doesn't look much, does it?

Note the grass: good season.

On the other side of the ridge I found a line of vertebrae exposed in the side of shallow gully. What an amazing sight!

The geology of the region is fantastic, regardless of the fossils.
