Lapworth Museum of Geology




 

We had a great day at the University of Birmingham's Lapworth Museum of Geology on Saturday. We were provided with refreshments on arrival then began our guided tour with curator John Clatworthy.

Starting in the main hall we were told about the history of the building from its beginnings as workshops, through to its use for housing ambulances and finally to its use as a museum.

We looked at some rare fossils from the early periods of life on earth and also the famous ‘teenager’ Allosaurus, with its foot and rib injuries. Next we came to the ‘wall of stones’, which shows examples of many different igneous, sedimentary and metamorphic rocks, weighing in at over 3 tons in total.

We moved on to the minerals section which is conveniently arranged in colour order and contains wonderful exhibits from all over the world, including a lead mine in Shropshire. According to John, some of them are exceptionally valuable, with individual specimens worth tens of thousands of pounds. Many fossils and minerals in the collection would have been found by local miners and other workers who would supplement their meagre wages by selling them to mine owners or collectors.

After lunch, we moved into the Museum's private rooms and were shown some stupendous items which are not regularly displayed, including ‘bendy’ flexible sandstone, a sheet of pliable mica and some beautiful jet objects.

 

 

Our visit was concluded with a viewing of many old and unique documents, including original geology maps, top secret WW2 geology maps for the Normandy beach landing sites and workbooks from the 19th century. 


 

We would like to extend our thanks to John and the Museum for such a wonderful tour. Members of the public can visit the Museum for free and we thoroughly recommend it!

Oak House, West Bromwich

 


Oak House at West Bromwich is a classic 17th century half-timbered house with an excellent visitor centre and gardens. As part of their annual archaeology event at the house, the Council invited us to dig a test pit to search for evidence of earlier occupation and to show members of the public what hands-on archaeology is like. Although the weather was very bad on Tuesday, almost 70 visitors braved the torrential rain to see what we were up to. Over the next two days the rain gradually eased and many more people came to look and talk about our excavation.

We'd been told by staff that during landscaping and construction of the visitor centre, large amounts of rubble had been spread across the site and covered with grass. A pile of rubble left over after that was was simply formed into a neat hillock - like a bronze age burial mound! - and turfed over. The gardeners told us to expect at least half a metre of rubbish before we got to 'the good stuff' and they weren't wrong. Finding a screw top jar and a pair of ladies tights below half a metre was a little disheartening to say the least but we soldiered on in the hope of finding better. By the time we'd finished, our test pit was well over a metre deep but on its western side we were still finding modern and Victorian rubbish right at the bottom.

A dark band representing rubble could still be seen at the bottom of the test pit

It seems the spot we had chosen to dig may have been where rubbish was piled against a bank because the eastern side of the pit gradually became cleaner as we went deeper. This diagram (not to scale)  gives an idea of how our pit cut through the layer of rubble and into the bank:


Notable pottery finds included a few sherds of what seems to be Cistercian ware, several fragments of fine vessels made from Midlands purple ware and a couple of tiny pieces of brown-mottled ware. A number of clay pipe stems and some bowl fragments were recovered as we descended, with the earliest examples perhaps as early as the mid-17th century. While we didn't find any incontrovertible proof of occupation earlier than the standing house, some of the pot-sherds could predate it by several centuries.

Pottery fragments and a very substantial pipe stem

We hope to be digging more test pits at Oak House in the near future, possibly a little closer to the building where we just might find traces of an earlier house.


 

Our test pit was just over the wall  from the formal garden
