What I hope exists already - it's been something that occured to me recently but I've yet to check - is an frequently updateable online parallel timeline of carbon and example dated discoveries in the UK and Ireland...a means of stepping back and comparing in order to get the bigger picture...a holistic approach, for want of a better phrase. We may possibly understand our forebears better as a result. If such a timeline does not exist then my personal opinion is that it should.
