Triassic Seed/cupule?


barkersaurus

Recommended Posts

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. Cheers,

Very cool seed! B)

Maybe some form of Cardiocarpus?

Thanks for posting this, Susan.

Regards,

EDIT: Susan, have you any idea which formations you are hunting in?

I believe it to be from the early Triassic, narrabeen formation of the Australian Sydney basin. Will check out possibility of cardiocarpis though!

Just did a bit of digging, could it be a Caytonia structure?

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. :unsure:

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.

Regards,

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.

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,

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.

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 :blush: ) 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. ;)

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.

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! ;)
