Triassic Plants ID

[Psittacosaur9]

Hello everyone, and hope you've all had a good day so far.

 

I am currently having a break after putting most of my bookcase together. Here are some fossil plants found in the Triassic layers of the Sydney Basin I would like identified if possible. As before, I would like the most specific identification possible, but don't mind genus or clade names if they'd be more accurate. I know the general location for these, so don't worry about that. If you need more photographs for a proper identification, I can take more in a couple of hours or tomorrow.

 

Specimen 1: Shale plant fossil

 

This fossil was found by a friend in the shale rock layer in the Northern Beaches region. This makes it Triassic in age. I read this document (https://www.researchgate.net/profile/Gregory-Retallack/publication/241677571_Geological_excursion_guide_to_the_sea_cliffs_north_of_Sydney/links/55d2119008ae0b8f3ef776a9/Geological-excursion-guide-to-the-sea-cliffs-north-of-Sydney.pdf) and after comparing the plant to various images on the document, I came to the conclusion that the plant was a specimen of the seed fern Dicroidium. Is this an accurate identification?

 

 

Specimen 2: Plant Assortment

 

This assortment of various plant fossils was found by another person I used to know in the Sydney Basin. I assume it is Triassic, as the vast majority of exposed sedimentary rocks in Sydney are of that age, although it might be Permian. I do not know the exact region. There seem to be multiple different plants on the slab, and they seem to be more poorly preserved than the shale layer plant. Does anyone know what they are?

 

 

Also, do any of you have any tips for getting better images? If I take any more, I'll probably use my SLR camera, as my phone's camera is terrible.

 

Thanks for the help!

 

Edit: Changed the title to make it more obvious this is a new thread.

Take your photos outside, in natural daylight, ... or at least near a window.

Noted, I'll take my future photos outside.

First one looks like a Dicroidium

I agree with Dicroidium for the first specimen, nice one! The second is likely Glossopteris, it's very common in the Permian around Sydney. I have a similar specimen which is apparently from around Wollongong somewhere, the preservation is attractive so would be good to figure out where they're from!

Now that you mention, it does look like fragmentary Glossopteris

Ok, thanks for the responses. I was wondering if the second one was Glossopteris anyways. Bit of a shame, as I've already got a better preserved Glossopteris specimen, but oh well. Thanks for the help!

I have a bit of a Glossopteris obsession 

With multiple specimens in my collection, ranging from nice complete leaves to plates of shrapnel bits. Am happy with them all

I can see why! They're very attractive fossils. I've got a nicely preserved specimen in my collection, and when I sort my display case out I'll post a photo!
