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.

Nice part section of a fossil tree fern from Jurassic Tasmania .

Grandfather Clocks and their cases – Brian Loomes

A first edition of this classic work published by David & Charles Newton Abbot, London in 1985.

Largish quarto, 352 pages, illustrated throughout. A very good if not better copy. Heavy, unsuitable for Overseas postage, subsidised by Voyager in Australia.

Brian Loomes was a Yorkshireman and new more about clocks than anybody. The book contains images of some of the greatest clocks the likes of which will surely never be made again. Now a collector’s book and maybe for the digitally challenged.

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!
