Its one of the basic rules of plants - don't have veins cross each other as they are basically one way from roots to leaf. Link to comment Share on other sites More sharing options...

Fossildude19 Posted July 10, 2021 Share Posted July 10, 2021 That is because I think it is some type of plant matter. Agree to disagree. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

I agree with Tim that looks like a plant leaf form but which Genus/species I dont know...Could be something else but for comparison here is a closeup of a present day Ficus lyrata leaf and its similar venation/cell structure. Regards, Chris 19 hours ago, G Mac said: I was wondering what these leaves are? Very neat finds! Not sure if there is enough fine detail/venation/attachment detail preserved to determine what the first 2 are. I'm hoping someone else will recognize the last specimen for you as I dont--its outstanding though! Regards, Chris 1 1 Link to comment Share on other sites More sharing options...
piranha Posted July 10, 2021 Share Posted July 10, 2021 The closest match available from McLoughlin 1996 (posted above LINK 1) is a fragment of Hausmannia sp. My guru of Australian paleobotany has replied this specimen is: Hausmannia crenata a dipteridacean fern. 3 1 Link to comment Share on other sites More sharing options...

G Mac Posted July 11, 2021 Author Share Posted July 11, 2021 Thank you for the references - they are very helpful. Hausmannia crenata looks like a good match for the specimen that has excited comment. Although this specimen appears move circular in each of the two lobes and less crenulated. The leaves in Photos 1 and 2 are fairly common in the sandstone but the possible Hausmannia is the only one I have seen. I was here over the wet due to covid and spent lots of time searching! I will print the papers for reference and keep tract of where I see what. All these are from Gantheaume Point Broome. 1 Link to comment Share on other sites More sharing options...
