This sample contains a sample of radiolaria, which are the remains of ocean dwelling proterozoa (a diverse group of unicellular eukaryotic organisms), which form silica rich skeletons. They are commonly 0.1-0.2 mm across, and form the siliceous ooze that covers much of the deep ocean floor.
The sample belongs to Geoff Mould and was mounted by Brian Darnton using 'Numount' embedding medium.
Cabinets of curiosities were personal collections of natural and man-made objects displayed in a single cabinet.
It was a fashion that reached its peak in the seventeenth Century, but something that is returning in modern times as uncategorised virtual or travelling physical exhibits, sometimes crowd sourced and changing. The original cabinets of curiosities were the personal and often idiosyncratic collections of wealthy owners, and their main function was to provoke a sense of curiosity and wonder in the viewer. Our Cabinet of Curiosities is a collection of curious things that we came across in museums, and a few things we've found in mineral shows. There isn't a learning objective – they're just interesting.
