Mike from North Queensland Posted October 13, 2014 Share Posted October 13, 2014 A while back when looking through some matrix I noticed a flash of colour coming from the side of one of the small pieces. As I have now recently purchased a 5 mp digital microscope for my computer I can now better show the specimen. The fossil appears to be fish vertebra and was found in the Toolebuc formation in the quarry just outside Richmond Queensland Australia. this formation is marine hence the fish and is contemporary in age to the opal fossils found at lighting ridge. The nearest opal field is about 300 kilometres south at Opalton hence opal fossils are not known to be found in the quarry. This as far as I know is the only one, but shows that there may be more. As for scale the longest side of the piece of matrix is 12 mm long. enjoy Mike D Link to comment Share on other sites More sharing options...

Mediospirifer Posted October 13, 2014 Share Posted October 13, 2014 Very cool! It's always neat to find something unexpected in the fossil collection. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted October 21, 2014 Share Posted October 21, 2014 What is the color of the mineral that has the specks of color? I wonder if is pyrite or mother of pearl. The colors don't look like most opal that I have seen. My goal is to leave no stone or fossil unturned.

Herb Posted October 24, 2014 Share Posted October 24, 2014 (edited) very cool It does look like Bornite crystals though.

The colors don't look like most opal that I have seen. I agree. It looks like the first stage of an oxidizing metal ore like pyrite, bornite or haematite. Greetings from the Lake of Constance.

Mike from North Queensland Posted August 4, 2015 Author Share Posted August 4, 2015 This is one I had forgotten I had posted. It looks and flashes like a normal opal in the hand and the vertebrae are only partially opalised The specimen is so small but interesting.
