This one is geology rather than catastrophism as a geologist is at the heart of the discovery. Channel 4 Had a TV programme about it last week which you can see if you missed it at ... (and see also

fossils in clay

Clays are formed by water action. You can say it is meltwater from draining ice sheets or tsunami like waves pouring over the surface of the earth (usually via river valleys). The exact interpretation is not easy to resolve but it is increasingly clear that in the Pleistocene there was a succession of watery events in some locations (especially at the bottom of ice sheets). Melt waters from the last Ice Age played a significant role in the levels of the Black Sea - and presumably the Caspian Sea also. It reached these locations by water flow along river valleys - such as the Danube.

Reef gets bigger

At ... the Great Barrrier Reef has grown in size due to findings by the Australian Navy. They have discovered a massive extension of the reef that exists behind the more visible Great Barrier Reef that is seen by the public at large - on the deeper sea floor. Enviros worried about the reef being in its death throes were recently shut up for a while by a survey which showed only a very small percentage of the reef is damaged by bleaching (which appears to be a recurring natural process and nothing to do with human activity).

Plate Tectonics Mars

Yes, plate tectonics on Mars - you heard that right (go to ... (alternatively, ...  An Yin, a UCLA scientist, claims rudimentary Plate Tectonics occurs - just below the surface. Basically, he has studied satellite images beamed back from Mars and has decided certain features look like a fault system, somewhat similar to what he has seen for himself on the Earth in the Himalayas and Tibet.

oceanic crust

Most oceanic crust is thought to be no more than 200 million years of age. This is necessary if Plate Tectonics is a reality, the idea being that oceanic crust is continually being subducted under newly created sea floors. The idea of course assumes the planet has always been the same size as it is now in spite of the universe expanding and gas planets expanding and all kinds of other things in the universe expanding.

Ancient Tsunami

At .... work on the M4/M5 junction just outside Bristol (south Gloucestershire) has revealed a couple of bone beds going back 200 million years ago. A Kentucky undergraduate at the University of Worcester analysed samples taken 25 years ago (when the motorway junction was built or upgraded) and she has discovered they were not caused by a single flooding event, as previously deduced, but by more than one transgression event.
