BobWill Posted December 31, 2018 Share Posted December 31, 2018 Yeah Gerald finds some amazing fossils there with great preservation. Is this one fossil? I see several different surfaces so maybe it just has many sides with a variety of looks. The ones with the ring of knobs resemble some trace fossils identified as conostichus but they seem to come with a lot of different looks. Link to comment Share on other sites More sharing options...
dragonsfly Posted December 31, 2018 Share Posted December 31, 2018 Herb, A couple of them remind me of mammalian carpal bones. Don't know about that last one though...any 3D jellyfish ? Link to comment Share on other sites More sharing options...
dragonsfly Posted December 31, 2018 Share Posted December 31, 2018 Mawsonites, listed as problematic in DK's pub FOSSILS, Walker & Ward 1992, Listed as found in Australia, bears some similarities. No US findings listed however... Looking again at the last photo...could those be tube feet near the lobes, isn't the structure similar to an echinoderm? Head scratcher fo sho.

doushantuo Posted December 31, 2018 Share Posted December 31, 2018 slightly reminiscent of new Aspidella find: image from: Ediacaran discs from South America:probable soft-bodied macrofossils unlock the paleogeography of the Clymene ocean Maria Julia Arrouy,Lucas V.Warren,Fernanda Quaglio,Daniel Poire ,Marcello Guimares Soares,Milena Boselli Rosa,Lucia E.Gomez Peral * Nature Scientific reports (6) 30590 However: barring some weird form of reworking,totally unlikely in view of your remark about the stratigraphy Link to comment Share on other sites More sharing options...
Miocene_Mason Posted December 31, 2018 Share Posted December 31, 2018 Reminds me of petrodus denticles, perhaps related to that? 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
