barkersaurus Posted October 9, 2012 Share Posted October 9, 2012 Found this gorgeous little fella today in some Triassic sediment that had eroded out of a cliff near here. It was in a layer that also had a lot of Dicroidium leaves. I thought it might be a cupule, just looking for an accurate ID.

Fossildude19 Posted October 9, 2012 Share Posted October 9, 2012 (edited) Very cool seed! Maybe some form of Cardiocarpus? Thanks for posting this, Susan. Regards, EDIT: Susan, have you any idea which formations you are hunting in?

barkersaurus Posted October 10, 2012 Author Share Posted October 10, 2012 I believe it to be from the early Triassic, narrabeen formation of the Australian Sydney basin. Will check out possibility of cardiocarpis though! Susan 'soozasaur' Barkerfeatherspredatebirds.blogspot.com.au Link to comment Share on other sites More sharing options...
barkersaurus Posted October 10, 2012 Author Share Posted October 10, 2012 Just did a bit of digging, could it be a Caytonia structure? Susan 'soozasaur' Barkerfeatherspredatebirds.blogspot.com.au Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 10, 2012 Share Posted October 10, 2012 (edited) Susan, I suppose it could be, but I'm not sure the heart shape of your specimen really matches with reproductive structures, at least from the google image search I did. You might try to see if you can find some kind of flora list for the Narrabeen Formation. If you could get your hands on a flora found list, that would be helpful to narrow down the possibilities. Cycad seeds are a possibility as well - try Googling Cycadinocarpus. I believe it is known from the Triassic, but not sure if it is in your area. Oh the possibilities. Keep us posted as to what you may uncover. Cool seed, in my opinion.

Midwest Posted October 11, 2012 Share Posted October 11, 2012 Great fossil! Could be Pseudocidaris mammosa Echinoid... I am not an expert but that would be my guess. Link to comment Share on other sites More sharing options...
squali Posted October 11, 2012 Share Posted October 11, 2012 Great Find!! I don't have any suggestions for you regarding what it is but the detail is nice. I enjoy seeing fossils from around the world. The distribution and diversity of species on a global level is a fascinating subject. It's hard to remember why you drained the swamp when your surrounded by alligators. Link to comment Share on other sites More sharing options...
Coco Posted October 11, 2012 Share Posted October 11, 2012 Hi, Great fossil! Could be Pseudocidaris mammosa Echinoid... I am not an expert but that would be my guess. Do you want to explain what leads you to think that this fossil (in the 1st post) would be a Pseudocidaris mammosa ? I see nothing which looks lile a sea urchin. Then I would be very incapable (not able) to give a name.... Can you learn me more please ?

Coco Coco, You could certainly teach me a lot more than I can teach you. I thought it resembled a club spine when I replied last nite. Now that I look at it again and read everything again... I guess I am wrong. Link to comment Share on other sites More sharing options...

Now that I look at it again and read everything again... I guess I am wrong. I've been wrong too many times to count, so don't be discouraged. Sometimes it helps to have a different view of things. One of the things I've learned on the Forum here ( the hard way ) is that you always need to take a good look at the pic, and read through all of the posts carefully, or you could miss something relevant and important to the discussion. No harm done. Regards, Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

piranha Posted October 25, 2012 Share Posted October 25, 2012 It looks like the corystosperm seed: Alisporites These are found in association with the large fertile cupules of Umkomasia and foliage of Dicroidium at Narrabeen. Link to comment Share on other sites More sharing options...

Thanks for posting this Scott. I've been watching this thread hoping someone would bring something to the table. Should've known you'd come through for us!
