New Members G Mac Posted July 29, 2018 New Members Share Posted July 29, 2018 These inclusions are in Broome WA Australia sandstone possibly just higher than the famous dino-foot prints. The shape, relative thickness of wall and lumen, the layout and spacing on the platform, and some of the detail on them, all remind me of sponges. Can anyone confirm. If so there is about an acre of them! The longer ones all lie prone or are aligned in the same direction. A fossil sponge garden or cruel geological hoax?

ynot Posted July 29, 2018 Share Posted July 29, 2018 They could be sponges, but I think they are concretions. Particularly in the third picture there is clear layered bands, not very sponge like (in My opinion). 1 Darwin said: " Man sprang from monkeys."

FranzBernhard Posted July 29, 2018 Share Posted July 29, 2018 Sure not a geological hoax . Its something quite spectacular and beautyfull, whatever it is. Are these things somewhat rusty? In other photos, they appear green - are there algae on them? Is the area wet in some pictures? And: In the last photo, it seems that one ot these things is missing at the right edge of the photo - ?? Franz Bernhard Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted July 29, 2018 Share Posted July 29, 2018 I would lean towards some really weird concretions, but they could possibly be stromatolites? Very interesting. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
abyssunder Posted July 29, 2018 Share Posted July 29, 2018 I think, they might be close to the Thalassinoides XL mounds / openings shown below. Fig. 6. Sedimentary facies. (C) Muddy sands (facies C).

I agree; the shape of many of those objects (red arrows) does not fit with the hypothesis; moreover, if the one indicated by the yellow arrow is part of the whole, it does not even have an opening.

Plausible?????? 1 Link to comment Share on other sites More sharing options...

Franz Bernhard I've had the same doubt when looking at this pic so, just a wild guess: modern thrombolites? https://www.google.it/search?q=thrombolites+lake+clifton&tbm=isch&tbs=rimg:CYU74pb9AKLTIjhGhl6hmX_1AUvl4jpRPlE8umtsbGF389pVQYL7Z_1HtdgJPV1g5_15HnXtHFabr2_1l4sEobxasaU93SoSCUaGXqGZf8BSEe8ynPUYom4WKhIJ-XiOlE-UTy4RV53Ju8BCjK0qEgma2xsYXfz2lREY3GyoE0eC4ioSCVBgvtn8e12AEe_1TaxsKsc1PKhIJk9XWDn_1kedcRHte5YHQ2ytQqEgm0cVpuvb-XixG-x7BvFnMDYCoSCQShvFqxpT3dEQoa98hRjjll&tbo=u&sa=X&ved=2ahUKEwjGj5OG7dLcAhWSyoUKHdG0DEIQ9C96BAgBEBs&biw=1517&bih=705&dpr=0.9#imgrc=YfF5gma1ywi0zM: Link to comment Share on other sites More sharing options...

fifbrindacier Posted August 4, 2018 Share Posted August 4, 2018 Hi, your specimen make me think about paramoudras like the ones we can find in the North West of Spain in the site of Jaizkibel, Basque country. Those concretions are the fossils of the activity of micro-organisms that digged galleries in the marine soil during the sedimentation. Those perforations must have acted as canals during the diagenesis, permitting the circulation of water and so, the precipitation of silice at their periphery. 3 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux." (Antoine de Saint-Exupéry) "We only well see with the heart, the essential is invisible for the eyes." In memory of Doren Link to comment Share on other sites More sharing options...
