HI all
Ive seen a few Tasmanian fossils in the past, on the River Derwent, Maria Island and North West of the state and never thought much about them other than dating the ages of the sedimentary sequence to get a better idea of the past. Today i found a Permian marine sequence West of Queenstown, chock full of bivalves and plants, so know its Permian. The reason its interesting to me, is plenty of exploration companies and geological surveys have explored the area when it was barren easy ground to walk on and only noted the plant fossils so may be a unique find? I have seen the same marine fossils at Black Bluff and further East at Bell creek and both areas have been associated with older alluvial gold trapped in sandstone. So try and compare. This is not in Silurian. The marine fossils i found today are abundant and only occur in a very small strip of land. Dating it is easy, its Permian. 250-290 million years ago, so relativity new. But everything i read in every report says it has to be earlier, Cambrian even, very confusing. I dont have my camera on hand but can show generic photos of them if needed. but they are not as advanced as the Parmeener Super Group fossils and im no marine biologist, but from their size know it was shallow breeding beds. they look like Pippies and barnacles with the odd seaweed thrown in. Its a rich strip of them, chock full of em.. and the only one i have hit here.
just wondering if anyone has any knowledge on Tasmanian fossils, if so, What i just found sub dates our west coast geology by hundreds of millions of years? With specimen in hand, The same colour sequence of the mudstone (misnomer?) is seen in the north scraping on Mount Lyell so know i need to drive further south to hit mineralization. It may not mean much to most but for me to be able to glance 6km or so away is pretty cool prospecting, found with my eyes. no extinct, 250 million year old critter in the greatest extinction rate the earth has ever seen, was harmed the process.
