Dino bone from the famous Lightning Ridge opal mines leads to first ID of this rare type of predatory dinosaur in Australia. A second, 20 million year older example also recognised during their studies. https://m.phys.org/news/2020-01-predatory-dinosaur-added-australia-prehistory.html

Fairly recent bit of opal fossil research
The Amateur Paleontologist posted a topic in General Fossil Discussion
After learning about Weewarrasaurus, I thought it'd be nice to report the 'lesser-known' recent bit of research about the opalised fossil site Lightning Ridge (New South Wales, Australia) It's basically the most up-to-date paper dealing with the geology - including age, stratigraphy and lithology - and vertebrate paleontology. The paper provides many new details about the Griman Creek Formation (GCF), a Cenomanian (mid-Cretaceous) formation which crops out in the area around Lightning Ridge. The GCF is a formation especially known for its diverse vertebrate paleo-ecosystem; of which many spec- 3 replies

Hello All, I was hoping that someone could help me identify this bone? its from the mid-Cretaceous Griman Creek Formation of Lightning Ridge Australia I don't think its a yabby button or turtle shell, as the piece is not rounded like a yabby button and there is bone texture. the piece is bilaterally symmetrical and there appear to have joins or groves where the bone meets. The underside is not flat like I would expect for turtle shell... Looking forward to your replies Rod

I love the useful information on the fossil forum. For something different I have posted some pictures of where I "mine" fossils from 20m underground in an old opal mine. I am extending an old mine tunnel to find occaisional opalised fossils. The first picture below shows my current tunnel and the second picture the "rock" layer that contains traces of opal and opalised fossils. The rock is quite weathered and can be dug out with an electric jack pick. The majority of fossils that I find do not have gem opal colour play, but they do have exceptional presevation.

From the album: Opalised Fossils
Name: Opalised Pine Cone Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 16mm long Notes: This is an opalised pine cone from Australia. It is quite a rare specimen and is a great addition to my opal fossils collection. This specimen was kindly given to me by my friend Shaun. Thanks mate! -

Name: Opalised Bivalve Shell Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 25mm Notes: This is an opalised bivalve shell from Australia. Unlike the marine shells from Coober Pedy, the other hotspot for opalised fossils in Australia, the shells from Lightning Ridge are less common and come from a freshwater river environment. This one is open, and clearly shows the ridged pattern of the shell it once was. A nice addition to my opal fossil collection. -
