19th September - Two Somerset Quarries

FRIDAY 19th September
Ashen Cross Quarry, near Somerton and Bowdens Lane Quarry, Langport
Simon Carpenter and Richard Ashley
This meeting visits two working quarries. In the morning we will visit Ashen Cross Quarry where the very lowest beds of the Blue Lias are worked. Following a pub lunch in Somerton we will visit Bowdens Lane Quarry where beds in the White and Blue Lias are worked. 
Please note that this meeting is being held on a Friday, as access to these quarries cannot be obtained on the usual Saturday. Hard hats and high visibility jackets or vests are required and the party will be limited to 16 so bookings are essential. Collecting is permitted.
Meet at 10.30 am at Ashen Cross Quarry south of Somerton. Grid reference ST 495 275.

Giant swimming dinosaur

A giant fossil, unearthed in the Sahara desert, has given scientists an unprecedented look at the largest-known carnivorous dinosaur: Spinosaurus.
The 95-million-year-old remains confirm a long-held theory: that this is the first-known swimming dinosaur. Scientists say the beast had flat, paddle-like feet and nostrils on top of its crocodilian head that would allow it to submerge with ease.
The research is published in the journal Science.
It had a long neck, a long trunk, a long tail, a 7ft (2m) sail on its back and a snout like a crocodile. When its body proportions are examined, the animal was clearly not as agile on land as other dinosaurs were, so it probably spent a substantial amount of time in the water.

New branch of life?

A mushroom-shaped sea animal discovered off the Australian coast has defied classification in the tree of life. The tiny organism does not fit into any of the known subdivisions of the animal kingdom.
Such a situation has occurred only a handful of times in the last 100 years.
The organsims seems to have several similarities with the bizarre and enigmatic soft-bodied life forms that lived between 635 and 540 million years ago - the Ediacaran Period.
 These organisms, too, have proven difficult to categorise and some researchers have even suggested they were failed experiments in multi-cellular life.
Two new species of mushroom-shaped animals have been recognised: Dendrogramma enigmatica and Dendrogramma discoides. Measuring only a few millimetres in size, the animals consist of a flattened disc and a stalk with a mouth on the end.
