I have edited the image using a basic photo editing app to highlight its features using filters on an iPhone XR but no false colours used, also a normal image without editing at all.
Any clues/help on this?

It is very unusual to preserve soft parts of animals (eg a tongue).
Gimp, it is not quite that simple. The volcanoes do not PRODUCE fossils but volcanic activity can preserve fossils - so volcanic rocks and fossils are closely related. Fluid lavas are only one type of volcanic rock. Tuff (the fine volcanic silica "ash" blown into the air by volcanoes) falls on animals and plants and buries them - think of the human fossils at Pompei and Herculaneum. Mud flows, caused by the release of water and liquification of volcanic products like tuff sweep down mountainsides and bury everything in their path, a common problem in places like Indonesia and the Philippines - this also occurred at Mt St Helens. The volcanic rocks of the Dandenong Ranges are mostly not lavas but are welded tuffs (tiny shards of volcanic glass that was still hot and plastic when it settled out of the air, so the shards welded together as they accumulated, forming a hard rock. Streams flow in the intervals between each volcanic eruption, depositing sand, gravel and clay with dead animals and plants - thin layers of the resulting sandstone, conglomerate and shale then occur between thicker layers of welded tuff and lavas, as in the Dandenongs and nearby volcanic complexes. And fossils ARE associated with them - fossil fish and plants are the most common (e.g. Briagolong, Mansfield, where I used to collect themGimp said:I think you might have missed basic geology at school. Ancient dormant volcanoes do not produce fossils. You need deposition not volcanism
I think a lot of input here are only guessing so yes need someone with knowledgeGimp said:Seeking amateur opinions on here is only falsely stroking your incorrect ideas
Yep - get them into the museum as I am sure there are many here that would like a definitive answer from experts.Martyz said:Hi Fossilon. The responses to your posts are based on incomplete evidence so they can be considered opinion and are, in part, probably only meant to be that. That does not mean you are being given amateur opinions.
Its great that youre sharing your finds and Im looking forward to learning more.
Not so (strictly). Australia has active volcanoes on Heard and McDonald Islands. Aborigines witnessed active volcanoes in South Australia and Victoria only a few thousand years ago, and that volcanism is not over. We still have molten magma in magma chambers under Bass Strait, and it is likely that they will erupt some time in the future. "Davies said the plume is now placed under the Bass Strait, which lies between Victoria and Tasmania". "Geologists suspect an earthquake that originated 50 kilometres from King Island in February 2002 signalled the reawakening of the hot spot - this is known as the East Australian Hotspot"Ded Driver said:Australia doesn't have any actual 'Dormant Volcanos'.
All volcanos in Au are extinct.
All true but no connection with ops finds. Devion fishes are a long way geologically from frogs, crocodiles and even further from hominids.goldierocks said:Gimp, it is not quite that simple.

However I am a but sceptical about the interpretation of these examples as fossils, but one needs to see more than just photos - hence my advice to take them to Melbourne Museum. I have mates who specialise in this (mainly dinosaurs and megafauna). IF they are fossils, they probably relate to post-volcanic streams and lakes that postdate the volcanics though, the volcanics there are Late Devonian and these species would probably be younger (but I am no expert).

"the whole province is volcanically active and the new one could literally be anywhere, but the most likely place will be between Ballarat and Geelong.
Yes, I would not hold your breathe.....Ded Driver said:I never trust what I read in the media. They have a habit of adding fertiliser ( oop: ) to make it seem bigger, scarier & about to happen to everyone.
So as Goldierocks pointed out, there is a hot spot under the Bass Strait, but the likelihood of it rising to the surface & erupting tonight, or tomorrow, or any time very soon, is very unlikely.

But .... lets just hope Melbourne doesn't look Pompei next week :skull: layful:
