Pterosaur

[Andre Pterosaur]

Look guys I am not a Paléontologue I just say what Paléontologues told me , just tell me what do you think about theses rare opalised Gastropods.

Now the opalised fossils, Gastropods , shell, worms tubes, barnacle etc in that sandstone is just incredible.

on the second pictures you can see the green pine fire on the opalised Gastropod coil .

talking about soft organ mummified I know a man died at the table on his sailing boat , he has been mummified by the salt of the sea, 

the same as the people of Pompéi they were mummified by hot ashes.

we learn every day of new facts 

Theses opalised bones were hollow and the replacement by silicate is just incredible.

If the "mummified snail" was that extraordinary, it is odd that the paleontologist did not offer for you to donate it for study. Until it is published in a peer-reviewed science journal, it remains wishful thinking or unsubstantiated opinion. 

 

So, in terms of your specimens, what precisely do you want us to say about them? Have we not been commenting on them already? 

[Andre Pterosaur]

It’s pity’s that the camera can’t take the sharp  colours as real, on the video the colours are dull but it give a nice looking.

People’s working for museum are very strange I had 3 bad experiences.

i try to give my opalised bones , my collection of opalised Gastropods etc . Under the government cultural gift programs, 

they told me it’s to much paper works . !

so I gave them a split opalised wood , at one end it’s completely opalised and at the other end it’s petrified. So a rare specimen.

my collection of opal will turn into jewellery and the rest will go to my family.

This sounds very fanciful. I know of no circumstances that could cause something like this.

 

Kear (2006) states; "The opal at Andamooka and Coober Pedy commonly occurs along cracks, faults or within cavities left by fossil remains. It may also on occasion directly replace fossilized organic remnants (probably secondarily), as evidenced by the frequent preservation of internal and soft tissue structures."

Thanks 

Now i learn more about theses opalised fossils .

I am specifically questioning this statement: "...an event appended, that snail got mummified instantly with the heat, and salt , it didn’t had time to retreat into the shell..."

[Isotelus2883]

I once read about a similar specimen but I cannot find it. I think it is possible that a snail got trapped in a pocket of high salinity water and dried out.

Lightning Ridge NSW Australia

Sommes miner’s are lucky if they find opalised Yabbies buttons a few pictures of them, the precious opal blue green is in display at the Opal center museum.

Lighting Ridge .

[Andre Pterosaur]

So beautiful.

[jpc]

I knw yabbie is a very Australian word, but what is a yabbie and what is its button?

Yabbies are Cherax destructor, an Australian crustacean of the family Parastacidae, which are freshwater crayfish found only in the Southern Hemisphere.

Not to be confused with gilbies ( Cherax quinquecarinatus).

Yabbie buttons are their gastroliths.

Exactly , Gastroliths , So beautiful.

 

Opalised wood

Lighting Ridge opalised fossils 

a pine cone, horn corals, 

 

[jpc]

horn corals?  In the Cretaceous?  

[Andre Pterosaur]

I bought a cylindrical volcanic rock.
it had a red pine fire that got my attention, so I cleaned it.

it must be one of the rarest black opal you can find .

it’s from Jundah Queensland Australia 

 

 

[Andre Pterosaur]

That horn coral not sure if it’s from Cretaceous but it’s beautiful, it could be a tooth otherwise !

but it doesn’t has the structures of a tooth 

[Tidgy's Dad]

Horn coral is sometimes incorrectly used to describe some solitary cone or horn-shaped scleractinian corals.

Though I am not saying that your specimen is one.

Edited October 24, 2023 by Tidgy's Dad

[Andre Pterosaur]

Ok so it could be a Nobby in similarity shape of a horn coral .

[Andre Pterosaur]

Does anyone can tell me what is it in that long 

opalised structure ?

 

[Tidgy's Dad]

Opal.

[Coco]

Opal is a mineral, it does not necessarily attach to fossils. All that is opal is not fossil.

 

Coco

[Andre Pterosaur]

Of course it’s opal 

but inside the opal the preserved remains is from the skull of the pterosaur or the jaw , because it was attached to the tooth .

i had to remove it from the boulder rock as it was in the way to remove more sandstone to clear the fibula .

It could have been one of the front tooth and a part of the bone of the jaws,

my theory is the pterosaur try to free it self , by biting an animal and got its jaws crashed by the plesiosaur or crocodile and died instantly and then got buried quickly at the right place where rich silica gels occurred so after millions of years the bones and teeth cavity were replaced by the silicate preserving the last remains in decaying stages.
