Curiosities

Fossil Fern – Lune River Tasmania – Early Jurassic Forest circa 182 million years old.

A nice slice of petrified tree fern from the Lune River area deep in the southern reached of Tasmania.

The dating of the examples in this location to the middle of the early Jurassic Period (182 Ma) was by isotopic measurements on zircons found in the volcanic sandstone hosting the fossils (Bromfield et al 2007). Also refer the excellent guide by P. Manchester.

Weighing 70gm and 16cm by 5cm.

This region is the area of the world where these plants developed. Twelve tree paratypes (arborescent) ferns and one bracken-like (rhizomatous) fern have been studied in the region. All of the tree ferns belong to the genus Osmundacaulis. This example shows clear and tight trachioles

These plants evolved in this region, the Australian portion of Pangea, all that time ago. Gradually they have spread elsewhere and appear in North-west USA … examples were only discovered in Eurasia in the year 2000.

Queensland Mineral – Rain Forest Jasper [Spherulitic Rhyolite] from the Mount Hay Volcano

Mount Hay is to the west of Rockhampton in Queensland. It is an extinct volcano and it was the volcanic environment that gave rise to this unique form of rhyolite. It is called rainforest jasper because of the rainforest like colour palette.

The underlying rock form is high in silicon and the long cooling process from the volcanic activity allowed for numerous inclusions of quartz, chalcedony etc.

A sizeable example 14.0cm by 9.0cm, 1.0cm deep, weighing 390gm

Striking Mount Hay Jasper – a nice piece

Rare Microscope Slide by Harry Webb – Transverse Section of Mistletoe – c1860

Harry Webb (1816-1866) was a professional mounter who lived in George Street, Balsall Heath, Birmingham England. His initials are embedded in the custom-made decorative slide papers.

A nice transverse section of the mistletoe stem.

There is a brief reference to Harry Webb in the key work by Brian Bracegirdle – Microscopical Mounts and Mounters (page 100) and an unattributed example (Page 39-P). we have this information from a later reviewer who knows their stuff – but we struggle to agree that the example shown in the book is from HW.

Webb’s work featured in several international shows and he is thought to have been awarded at least one prize. He was recommended by top line microscope makers. Unfortunately, something went very wrong and he took his life drinking phenol – which would not be a nice way to go.

Rare maker with definitive slide papers – 165 years old!

40 Patience Games – Bernard Stanley

This super little book came from a series of sometime unusual titles published by Universal Publications, London in the 1960’s.

For your amusement other titles in the series included … Thirty-Two Novelty Dance Moves; Recitations for All; Funeral Formalities and Obligations; Self-Protection; Fun with Matches and Matchboxes etc … we think the world has passed most of these by … but not without some loss.

Soft cover, 89 pages, plus adverts for other peculiar publications. Very good condition and the forty diverse variants of patience well explained often with diagrams as to how to go about them … we have played several and they were fun.

Patience the way it used to be played – not with the ipad but with real cards
