Photographs from the Harrow & Hillingdon Geological Society ‘Rock Show’ which was held 12th – 28th February 2020 at Uxbridge library. The three large ammonites below (15″ to 17″ across) are from the show and are from the collection of Bob Maurer of the H&HGS with his permission. Bob is a regular speaker to the AGS and also an exhibitor at our annual Mineral, Gem & Fossil Show.
The exhibition is well worth a visit with cabinets and tables full of interesting labelled rocks, fossils and minerals. See the Harrow & Hillingdon Geological Society website early next year (2021) for the exact February date.
Tropaeum bowerbanki (open coiled Hetromorph)
Lower Cretaceous 100 – 115 million years ago. From the Lower Greensand Ferruginous Band, Crioceras Bed, Atherfield, Isle of Wight. Evolved from an open coiled form in the Jurassic era to a closed coiled form in the cretaceous era.
Ammonite trapeum sp
Australiceras gigas, open coiled Hetromorph. Cretaceous era, 90 – 120 million years ago. Whale Chine, Isle of Wight.
Ammonite trapeum sp.
Australiceras gigas, an open coiled Hetromorph. Cretaceous era, 90 – 120 million years ago. Whale Chine, Isle of Wight.
Uxbridge Underground station, Metropolitan & Piccadilly lines, with carvings in Portland stone, a freestone, depicting railway wheels and carriage springs. Built in 1938 in an Art Deco/Modernism style there is some wonderful stained glass inside.
Just down the road from the station is ‘The Chimes”, or ‘Intu Uxbridge’, a large shopping centre with some wonderful polished limestone floors on the lower ground. They are covered in belemnites and ammonites, almost too good to walk on. Part of the phragmocone, or flotation chamber of some belemnites is preserved in many cases. In addition, the septa or chamber walls of the ammonites are also very obvious in many of the examples. The floor is Solenhofen limestone from Germany, Jurassic, 180 million years old.

35cm diameter x 2cm ‘Stepping Stones’ photographed in a U.K. garden centre. Too nice to walk on. Some Liesegang rings (?) and iron staining give a wonderful multicoloured appearance. These sandstone slabs possibly come from Bari Nagour, Rajasthan, India. It is named ‘Teak and Rainbow’. Watch the slide show……

Mike Howgate’s ‘walk’ on Thursday 6th April 2017 –
‘The Pulhamite Industry’ in Hertfordshire’.
Pulhamite is an artificial stone which was produced at a site near Broxbourne station from the 1830’s to the 1930’s. It was used in the manufacture of rockeries, fernaries, grottos and landscape features some of which look remarkably geological. We met up at a cafe alongside the river Lea then went to see the remains of the works, a kiln and bug wheel. After lunch we visited the Lowewood Museum to see their exhibition on the Pulhamite industry, which is on until the 28th. of April then it was on to the High Leigh Conference Centre to examine a Pulhamite ‘Millstone Grit’ gorge.
Southbank Foreshore walk with John Wong + some hardy AGS members 2nd March 2017
This is just a small amount of the interesting artefacts and even fossils that were found. Flint from being used as ballast in the past, as well as an old building material. Chalk from the ‘barge beds’ that were laid down on the shore for the flat bottomed barges to settle on when the tide was out. Large amounts of animal bones from restaurants and suchlike alongside the river in the past. Countless pipe stems and bowls from smokers past. A small bowl from the days when tobacco was much more expensive, larger bowls from more recently. Countless pieces of pottery, plain, decorated, glazed. Numerous pieces of iron work and steel from old boats broken up on the Thames shore. Coal from the loading wharfs that were scattered along the Thames. Lots of sand that had been deposited onto the shore for the 1951 Festival of Britain. Oyster shells, remains from an old fashioned meal. Tons of brickwork and stones from the Blitz and old wharfs and buildings that have gone to the Thames…..and a suspected Septarian Nodule or Concretion.
More photographs of the remaining part of the day……
