IN THIS ISSUE

FROM THE EDITOR Hello friends! Another year draws to a close, and we both look back at a year of great trips and forward to adventures to come.

We also pause to celebrate the life of Yvonne Davidson who passed away recently, and reflect on her years with the club and her dedication to it. Our thoughts are with her loved ones; she will be missed. Your intrepid editor is just back from dig #2 at Yass, working on my thesis - and looking forward to another trip in February or so. In this issue I’ve included some photos of the critters that acid-leaching, thin-sectioning, and microscope work reveals; in latter issues I’ll describe these laboratory techniques in detail. And - fingers crossed! - I’ll have some new, larger Silurian beasties to share, too... quite a menagerie is being unearthed at Yass, and I look forward to sharing it with you. - James Strong, Editor, Sydney

BELANGLO - Text by David Hindmarsh, Trip Leader Saturday 13th October 2012 The second attempt to get to this quarry this year was abandoned late on the Friday, before, due to the severe weather event of those days. Speaking to the owner late that day, I was told that the area was receiving heavy snow, rain and very strong winds. Who am I to argue, when trying to get a group of rockhounds into a working quarry! Considering that the January trip was also canned at the last minute, due to similar The Fossil Club NSW

weather- although without the snow- it makes me think that we are being told something However, the invitation still stands for us to visit. Who is going to put their hand up and claim a pleasant, mild, summer day for a club visit? The quarry shuts over Christmas/ New year, but we could try again late January or February.

INVERELL ROCKARAMA - Text by David Hindmarsh, Trip Leader Pat Edwards, Joan and Bill Zealy joined us, as well as ten members of the Illawarra Lapidary Club.

October 2012

Dealers and displays were held at the Town Hall, Friday and Saturday, with field trips to various localities, Friday to Thursday. I had emailed a booking some six weeks earlier, to guarantee going on the only fossil trip, (for bulbs!), on the Monday, but was denied that event when the property owner was called away on the day.

From Thursday 18th October, Diana and I joined others from our club, to visit the northern New South Wales town of Inverell, for their 2012 Rockarama. This annual event is run by the Inverell Lapidary Club, which, like our club, is affiliated with the NSW Gem and Lapidary Council.

Field trips every day included Sapphires, of course!, with a mix of visiting very old mine sites, for minerals such as Tin, Lead, Silver, Pyrites etc or Quartz and variant crystals, and other locations having us collecting Tourmaline, Grass Stone, or sieving for Jelly Bean crystals, and some very lucky few, Diamonds. What Diamonds found were very small.

Shire, for road construction, and is being trucked out each day at a great rate!

Image: King Conrad Mine A quick search gave us several nice finds. The Council workers present were, in the main, unaware of what they were carting away!

Other than a few “planted” Sapphires, of reasonable size, but questionable quality, all Sapphires found, including those taken from commercial fossicking localities, were of a small size, with very few “cutters” being claimed. This is now typical of the whole Inverell/ Glen Innes Sapphire area. As usual, most people came home with a special find, with the more serious Sapphire hunters, giving up on sieving, and fossicking with their wallets at the Town Hall!

Returning home had us stop at Cessnock, to drive the fire trails. Several large, complete, special finds were quickly bucketed; A Spirifer with 9.5cm “wingspan”, and two “scallop “ type shells, 6cm and 8 cm. This location is still my favourite, and never fails to give up superb specimens. I will take them to the Christmas party for identification. IF ANY MEMBER HAS CURRENT INFORMATION ON ANY LOCATION THAT THE CLUB MAY ACCESS OR VISIT AS A FORMAL CLUB OUTING, PLEASE EMAIL OR PHONE DAVID.

Going to Inverell, we stopped at the Singleton location recently visited by the Club, and collected a bucket of Glendonites, then the Tamworth quarry to get Lepidodendron fossils. This quarry, as typical, is used by the local The Fossil Club NSW

CLUB MEMBERS CONTRIBUTE TO GEOLOGICAL SURVEY PUBLICATION

recent Inverell outing did not work to other people’s timing.

It’s here - and it’s a beauty! The June 2012 issue of the Quarterly Notes is on the “Permian fossils and palaeoenvironments of the northern Sydney Basin, New South Wales” and features perennial club favourite, the Mulbring quarry - and includes specimens collected by club members, some very rare. Ian Percival, Senior Palaeontologist at the Geological Survey of NSW and fellow member of our Club, will deliver a talk to the Club on the Mulbring fauna in February. If you haven’t seen a printed issue, you can download a PDF copy here: http://www.resources.nsw.gov.au/__data/assets/ pdf_file/0009/447048/QN138.pdf

With the temperature forecast for mid thirties, it was a hot run North, from the South Coast of New South Wales. We arrived at the property at 2.30pm on the Monday, thunder to the near South, very hot and calm. The van was quickly unloaded, smaller – lighter- columns were gathered, and loaded, as BIG raindrops splattered on us. Quickly we reloaded our gear over the stone layer, the tailgate and rear window then shut to keep contents dry.

GLEN INNES: BASALT COLUMNS - Text by David Hindmarsh Trip Leader’s ramblings: Diana and I did a four day round trip to Glen Innes area to get a box trailer load of basalt columns as garden landscape decorations. This trip happened as the planned event following the The Fossil Club NSW

With lightning all around us, thunder reverberating off the surrounding hills, and rain increasing, we quickly sourced a selection of longer columns, using a trolley and timber ramps to load the trailer. Everything loaded and covered, a well earned cool drink, and we headed back to the blacktop road two hours after arriving, now hot, wet but very happy with our haul. Having planned to spend the night at Glen Innes, but with black, lightning filled skies around us, there was no real decision but to turn South, keeping out of the heaviest rain, to spend the night at Uralla. With the continuing forecast of very high temperatures, and more storms, we drove South, stopping at Singleton, for a quick bucket of Glendonites before heading on.

The offices of NSW Trade & Resources & Energy, 516 High Street, Maitland, is well worth the visit for Geology and fossicking information and maps.

CLUB ON FACEBOOK Hi all: Well our Club has taken another step in the direction to try and keep the Club interactive for all members. We now have a Facebook group page called The Fossil Club of NSW and you can request to join by searching the folowing link: http://www.facebook.com/groups/ TheFossilClubofNSW/ This is an interactive site that is designed only for members of The Fossil Club of NSW where all members can upload comments, questions, start coversations and put up as many photos for everyone to see. So far we have four members and the disscussions have already begun about fossils and fossil locations. -Mick

YASS: UNDER THE MICROSCOPE - James Strong, Editor What follows are a few micro-snapshots from specimens collected at Yass as part of my studies. The work will conclude in the latter part of 2013 - but I’ll be sharing some preliminary discoveries and write-ups with you during the course of the year.

Above: We have no idea (yet) what this is... a small number have turned up in the thin sections. The main body is about 3 millimeters across, with a “spine” on both sides. It is also in the image below.

Above: A thin section from the Barrandella Shale: a slice of rock is mounted to a glass slide and then ground down to translucency - and then it’s put through a microscope scanner. Expanded to full size, each pixel in this image is only 1.7 microns (millionth of a meter) - which makes for an enormous image. Seen here are brachiopods (the “large” crescents), crinoid debris, trilobites in cross section, minute corals, and various mysteries. In the coming weeks I’ll mark up several of these images in detail - stay tuned! The Fossil Club NSW
