Greeks in Canada

Robert also sent in this link at ... did ancient Greeks sail to Canada. The idea if is based on something mentioned by the Greek author Plutarch. Did they reach Canada in around AD56? A character in a text of Plutarch is said to have claimed he had recently returned from 'a great continent' - and that is about all the evidence is. What was a great continent in the eyes of the sailor. The newly conquered Britain (by the Romans) is bigger than your average Mediterranean island.

Maya and LIDAR imaging

Robert sent in the link ... which concerns the use of LIDAR technology to peer through the tree canopy and image the ground surface below. We have seen it in action in the UK producing stunning results by looking at the woodland floor. Now the technology has been applied to the tropical forest zone of central America. In this instance, Guatemala - where an astonishing amount of Mayan archaeology has been revealed. All they have to do now is beat a path through the jungle.

Fireballs and Ice Age

Sent in by Gary - at ... here we are back at the Younger Dryas boundary event. If nothing else these guys are persistent. Every time mainstream gives them a kicking up they pop with another major paper. This times it is a barrage of fireballs as a comet fragmented and disintegrated in the atmosphere, creating a series of rapidly descending meteors that they claim torched a considerable part of the landscape. Geochemcal and isotopic markers have left behind a lot of evidence of their passing.

Stone Tools India

Javan sent in two links to this story - ... and ... a cache of stone tools from SE India, not far from Chennai, has thrown up a change in tool use at the 200,000 years ago mark. Acheulian hand axes have a long time longevity, it is thought (see belwo) ...

More on Dinosaurs

William has picked up on another dinosaur story at ... a slab of sandstone found at the NASA Goddard Space Flight Centre in Maryland contains at least 70 mammal and dinosaur tracks - showing they coexisted. The sandstone was a rock outcrop spotted by a guy that had dropped his wife off at work. He is described as an expert on dinosaur tracks - and what caught his eye was a 12 inch wide dinosaur footprint.

Mongolian dinosaur cemetery

Gary sent this link to his web site - at ... which refers to an article I looked at but did not report, on the presence of dinosaurs in the shifting sands of what was in the Cretaceous era, supposedly an earlier version of the Gobi desert. This basically ignores the fact that Mongolia at that time may have been situated somewhat south of where it is now. The UK was certainly in a more sub tropical position - so why is it assumed Mongolia was close to where it is now.

Greenland Getting Colder

The conspiracy continues, it would seem. At ... a guest author says, Greenland is getting colder but please, keep believing it is getting warmer. It would seem satellite measurements show parts of Greenland are getting colder - but climate scientists urge people to think in terms of this as a blip as climate models say Greenland 'should' be warming. The models don't lie.

Giant Earthquakes

At ... giant earthquakes are not as random as thought. Analysis of sediment cores from lakes in Chile show that EQs reoccur at regular intervals. It is only when smaller EQs are added that the incidents show up randomly in time. A Chilean EQ in 1960 had a magnitude of 9.5 and produced a massive tsunami wave that pummeled the coastal regions and caused a wave that travelled right across the Pacific to kill 200 people in Japan. Strong EQs produce underwater landslides which are preserved in sedimentary layers.

Magnetic Poles

William sent in this link - ... apparently, earth's north and south magnetic poles, in the past, used to flip regularly, at 200 to 300,000 years intervals. Currently, we are led to believe, the poles have not flipped for the last 780,000 years. Is the dating methodology haywire and why do magnetic poles flip?

Stone Wall 23,000 years old

At ... I missed this back in 2010 - a 23,000 year old stone wall in front of a cave in Lalambaka in Greece, probably built to protect residents of the cave from cold winds or wild animals. It is apparently the oldest known example of a man made structure. It has all the hall marks of a Mesolithic repertoire but here might be a problem as Mesolithic people elsewhere appear after the end of the  Late Glacial Maximum (but this is slam bang in the middle of it).
