We are used to finding ammonites in various places in the UK, such as the collapsed cliffs at Charmouth in Dorset, dating back to the Jurassic. These creatures of warm seas have been studied for years and are part and parcel of the idea that the Dinosaur age was one of global warmth. This appears to be confirmed by the discovery of large ammonites on an island off the peninsular of Antarctica - proof of Jurassic and Cretaceous global warming - see http://phys.org/print266079227.html
This is really basic geology but I'm placing it under the catastrophism banner as it has a bearing on the recent hypothesis of a comet impact at the Younger Dryas boundary - now, in light of a paper by Bill Napier, regarded as the Earth encountering a Taurid stream of material rather than an impact event as such.

At http://cosmictusk.com/kobres-on-16th-century-se-american-impacts/ ... Bob Kobres reports on some interesting events. For example, the town of Thunderbolt in Georgia was named from the translation of a native word for the area when an unusual lightning bolt had formed a spring which tasted of iron and sulphur.
This is at http://phys.org/print264333845.html ... evidence of the end of Old Kingdom drought as recorded in the Ipuwer Papyrus (first intermediate period) has been found in pollen and charcoal preserved in buried sediments from the Nile delta. Several major drought episodes have been found, corresponding not just to low Nile levels but to precise setbacks in the civilisation of Egypt. The paper is published in the journal Geology (July, 2012) and the sediment core goes back to around 5000BC.
This can be found at www.phenomenica.com/2012/07/african-elephants-are-picky-eaters/ ... which is interesting as the same may have applied to mammoths. Elephants don't eat just anything but selectively choose what species they consume and which woody parts they find palatable. Elephants prefer the bark, stem and roots of plants and shrubs, or trees, rather than the foliage or fruit. Where might that leave the eating habits of mammoths in a frozen world?
In Shorter Science and Civilisation in China:2, an abridgement by Colin A Roman of Joseph Needham's original 1981 text, we have on page 84 ...
'In ancient times Kung Kung (one of the legendary rebels) strove with Chuan Hsi (one of the legendary emperors) for the Empire.
Angered he smote the Unrotating Mountain, Heavens pillars broke, the bounds with Earth were ruptured, Heaven leaned over to the north west, hence the Sun, Moon, stars and planets shifted, and Earth became empty to the south east'

Note that the idea of solar activity, or a downsizing of solar activity, is not part of the debate - here, at least.
At http://elpub.wdcb.ru/journals/rjes/v09/2007ES000250/2.shtml ...The Russian Journal of Earth Sciences (2007) had an article, 'Long term solar activity variations in the Pleistocene and their connection with abrupt climate change' ... it is interesting that as the role of co2 is increasingly seen to be much less potent than the doomsayers alleged that some scientists are looking to the Sun to explain the dips and peaks in temperature as apparent from ocean sediment cores and isotopes in ice cores etc.
At http://wattsupwiththat.com/2012/06/19/the-intriguing-problem-of-the-youn... ... there is an excellent posting by Don Easterbrook, a geologist from Western Washington University, on the Younger Dryas event, the periods preceding and following it, and temperature fluctuations within it. A lot of this is actually a bit of an eye opener - and the latest research. As the years have progressed a considerable amount of data has accumulated on glacial advance and retreat, especially when it comes to Scandinavia where the research has been intense.
