fossils:
Ye gods...
There's geovandalism - and then there's sheer f***ing insanity. Thousands of pre-dinosaur fossils are scattered in the rocks of the Guryul ravine, rated by geologists as the world's premier site for the study of species from the Permian period (299-251...Posted on January 28, 2008 3:33 PM • 8 Comments •

Bacteria and black smokers go back a long way
I tempered the other week's repost on some rather impressive 1.5 billion year-old black smoker chimneys, and the fossilised microbes found within them, with some words of caution about the 'clues to the origin of life' spin that the...Posted on August 21, 2007 11:10 AM • 5 Comments •
Evolutionary Humour, SA style
The last couple of days have been public holidays here - yesterday was National Women's Day - and today I took advantage of this to visit the Cradle of Humankind World Heritage Site - specifically the Sterkfontein Caves, a very...Posted on August 10, 2007 12:22 PM • 3 Comments •
The Boneyard #2
Given that it's only been two weeks since the last one, Brian has amassed a spectacularly long list of palaeontologically-orientated blogging, including my piece on the Precambrian black smokers. But don't worry, the rest is much better....Posted on August 7, 2007 12:51 PM • 0 Comments •
Precambrian black smokers
I've been reading a few news items today about fossilized black smoker chimneys from China. This rang a few bells, as I wrote about a paper which talked about exactly the same thing on ye olde blog back in January....Posted on July 30, 2007 11:52 AM • 1 Comments •
Monday links and an open thread
Currently what little creative energy I have is going into other writing (specifically, a really fiddly bit in the paper I'm preparing to resubmit), so here's a couple of links for you: A real time global earthquake map. Darn cool,...Posted on July 23, 2007 11:32 AM • 5 Comments •

Namibia: the stromatolites' last hurrah
Some of the more massive limestone beds in the Nama group are chock full of stromatolites, the remnants of sizeable Precambrian algal reefs. Technically, stromatolites are not true fossils, because the mineralised layers are not directly precipitated by the photosynthetic...Posted on June 22, 2007 8:48 AM • 2 Comments •
