This story was also in the latest issue of the journal Geology and is interesting as it raises questions about the Milankovitch theory of climate associated with the Ice Ages - see http://phys.org/print346065297.html ... which supposes the expansion and contraction of a northern ice sheet is influenced by cyclic fluctuations in solar radiation, inter-acting due to wobbles in the Earth's orbit that restricted sunlight in one hemisphere while the opposite hemisphere brightened.
At www.sciencedaily.com/releases/2015/03/150320112332.htm ... we have 'did a volcanic cataclysm 40,000 years ago, trigger the final demise of the Neanderthals?' - which is a paper just published in the journal Geology, already mentioned I think, in a preview edition, some weeks past, but now in its final format. At last they are mentioning a catastrophic event around 40,000 years ago after years of ignoring it.
If you saw the video of the expanding earth scenario some months ago at this space and then you might be interested in the rival, the same thing but with a constant Earth size and a busting apart at the seams as the tectonic plates push pieces of continent around - or roughly as it is thought to have happened.

Huffington Post - complete with all the scaries and some really weird comments.
At www.livescience.com/49937-ancient-reptile-tracks-mass-extinction.html ... we are told the end of Permian mass extinction event may even have wiped out marine worms and other burrowing creatures that make holes in the mud on the bottom of the sea. This appears to be an extinction too far - on the face of it. The researchers came to this conclusion as in the following era, the early part of the Triassic, massive reptiles had evolved, and their tracks are preserved in rocks in modern day Utah.
An article in February's Down to Earth (geology magazine), issue 90, ISSN 0969-3408 ... concerns discoveries in chalk quarries over the years. Most finds are never reported. It is only the odd quarrymen who will bring attention to an oddity, and inform a geologist. In turn, most academic geologists rely on others to do the dirty work, and in spite of this there are a surprising number of erratics in museum collections (donated over the last 100 or so years).
The mystery of the balls of metals found on the ocean floor are baffling scientists, we are being told at www.dailymail.co.uk/sciencetech/article-2957453/What-mystery-alien-balls...
A remote camera revealed the ocean floor is littered with these metal balls, and some patches are remarkably well spread. Entrepreneurs around the world have an eye on harvesting them - and making lots of dosh in the process.
Modern civilisation is a civilisation of petroleum. Some people think it is a simple thing to shut off the pumps and close down the pipelines and live on renewables.

In 2011 and 2012 there was a lot of volcanic activity off the Canaries which led to the study. The research found sedimentary material which contained small fossils of the Cretaceous Period - which seems to rule out the idea it was dredged out of the mantle (where volcanic magma is thought to originate).
