Jurassic Coast	Permalink

I believe that the best time to visit Lyme Regis is in the very early morning. My son fossil hunts while I pick my way over the shale and Blue Lias rock of East Beach, to 'the boulder'. Here I sit, angled so that I can see not just the sea - silver/grey at this time of year - but also I get a good, misty, sepia view of Charmouth to the east and imposing Golden Cap beyond.

Dorset's Jurassic Coastline	Permalink

Rogue fossil hunters have been banned from Dorset's Jurassic Coastline after two court injunctions were secured. The National Trust and Charmouth council won the first order banning a Somerset man extracting fossils out of cliffs over fears of falling rocks. A second injunction was also made by Taunton County Court banning "unknown persons" from digging in the area. Read more __________________

Kimmeridge Clay Formation	Permalink

Jurassic 'burn-down' events explain patterns of organic matter richness in Kimmeridge Clay Formation The sediments of the Kimmeridge Clay Formation were deposited during the Late Jurassic between around 160 and 145 million years ago, the age of the reptiles. They are the main oil source rock in the North Sea. However, within this unit beds rich in organic matter are interspersed with organic-poor sediments. New evidence demonstrates that organic-poor sediments were probably caused by post-depositional loss of organic matter during so-called 'burn-down' events. The Kimmeridge Clay Formation is named after the English village of Kimmeridge on Dorset's 'Jurassic Coast,' a favourite haunt of fossil hunters. The sediments comprising the formation, which is particularly well exposed here, were probably deposited in shallow marine environment with an average water depth of 50-100 metres. 'We were particularly interested in the transition between organic-rich and organic-poor sediments' - Dr Ian Harding of the University of Southampton's School of Ocean and Earth Science at the National Oceanography Centre, Southampton (NOCS), and a member of the team that investigated the underlying processes.
