Oak, Beech, Chestnut Family Trees Found In Eocene Deposits of Gondwana
Scylla posted a topic in Fossil News
The ancestors of these trees are almost never found south of the equator, until now. https://m.phys.org/news/2019-06-argentine-fossils-oak-beech-family.html -
Last week took a short drive (11 miles of road and 3 on beach) to our local fossil area. 99.9% of our finds are plant parts. Mostly Alder and Willow leaves with some Meta Sequoia tossed in. Some times a birch leaf will find its way in. In the right rocks I've found a number of what I believe are alder cones as well.. After I get back home I'll start working on IDs. Unfortunately the literature is scant but was given one that has some local info. Some planes will have single leaves in good shape. While others are stacked on top of each other but the leaves are damaged. It looks like they preserved after they started to rot. There are other areas with a wider selection of leaves but you have to take a boat. And with our tide changes (between 7-25ft) it can take some planning. I will add more once back home and can work on more photos

Hi, I found these in the Carbonado Formation Washington State. 42 - 47 million years ago. Eocene under a coal seam. I found this bark of some mysterious looking tree. Around the same rock were tons of leaves, all similar to one species (except one leaf which I will also include). I am hoping people can identify the family of tree for me. I also am posting some strange "cattail" / "horsetail" like stem / leaf because this could possibly be a branch from this tree. disclaimer: I am still trying to figure out my phone. The last photo is more clear, larger and detailed. The only difference was, I held my phone sideways. Maybe this is what I will do in the future. First I will post the bark

I found this fossil in Newcastle, Australia. I believe it is three glossopteris leaves and some fragmenary material. Is this correct?
-
How’s everybody doing? I’ve got some fossils I need ID’d. They are from the Manning Canyon Shale in Utah. They are Late Mississippian/Early Pennsylvanian in age. Thanks!

Much has been already said about Florissant, so I’ll be concise with my words. 34 MYA, lake environment, ash fall, pay dig. Controlled hunt: they dig and dump piles, you select chunks and split them at picnic tables. Not the death defying adventure I crave, but fun to do once, fill a Riker with common finds, and say I’ve been there. You can buy the same rock and have it shipped to you, but since we were in the area, I prefer the on-site experience and selecting my own rock from the piles. Hint: Skip the blocky and/or grainy stuff and target the thinly laminated, shaly stuff that is beginning to split on its own. If you see black organic matter, even better. Exploit those planes. A montage of pics follows.

If you go to the beaches around Newcastle, Australia, expect to find many glossopteris fossils!
FrostbyteFossils posted a topic in General Fossil Discussion
These are some fossil glossopteris leaves from different beaches around the Newcastle area. The rocks they are found in tend to be very hard to break, but yield lovely fossils. Good luck! -
This weekend I went on another fossil hunting trip with my dad. We went to a place called Bacchus Marsh which is around 65 km east of Melbourne. Here we went looking for Tertiary plant fossils such as Laurus and Cinnamonum. The site was a creek bed under an old bridge. The bridge was located next to the Western Freeway which connects Bacchus Marsh to Melbourne, and extends north to south, eventually emptying into the Werribee river (about 2km away). The creek also goes under the freeway through two tunnels and you can look for fossils on both sides of the freeway, but the side near the bridge had the best rocks. The rocks we looked for were Ferruginous sandstones which are late Paleocene (59 million) to Middle Miocene (14 million). The creek was dry and it didn't look there had been water in it for a long time.

This is not a great photo, it was taken after sunset at the site of discovery, and it's a bit dirty. I still need to trim the huge chunk and wash it off, and it now sits in a spot with poor lighting, so this is the best I can do for now, but maybe someone who knows Cretaceous flora can suggest an ID for these leaves based on the general outline? The one on the right especially has 3 clear lobes, and note the stems. Platanus? I have never found this type before, in 9 years of collecting up there.

I have shown many people these... I believe they are leaves... Can anyone else see the overlapped leaves? Or negative images... Not your typical leaf fossil I know... Curious if anyone else can see it....

I received this relatively large fossil about 4 years ago as a Christmas present from a friend. All the information I have about this specimen is that "it comes from the Carboniferous", it was bought from a peddler at the local Christmas market without asking for the provenance. Now I am trying to definitively identify it. I compared it to all my fossil ferns and to many pics online, and some photos of Pecopteris polymorpha are particularly similar in shape. ^This is one of the images I found online. There is a surprising similarity even with the surrounding matrix, could my fossil come from the same formation? My specimen measures about 180 x 140 mm.

Are there any better resources to ID Green River flora/fauna?
Shamalama posted a topic in Questions & Answers
So I've been trying to do some research on the fossil flora/fauna of the Parachute Creek member of the Green River formation and so far I can only find the following reference mentioned as representing any kind of significant effort to catalogue the fossils: "The Eocene Green River flora of northwestern Colorado and northeastern Utah, HD MacGinitie - 1969 - University of California Press". The problem is, it is out of print and not even listed on the U of C Press site. I found a copy available from a book seller but I'm not sure if it's worth the money to buy it sight unseen. I already have plenty of other books like that already on my shelves. There is a database of sorts that the Denver Museum of Nature and Science has online, but I'll be darned if I can figure out how to work it. Any other suggestions? -
Hi, I would like to show you some plants that I found in the (middle probably) Bathonian of the soutwestern France, near the edge of the "Massif Central". So, I will describe the context of the find quicly : We can find some vegetals in micritic layers intercalated in sublitographic-limestone layers, very often they're fragments of lignitized wood (sometimes with a wonderful conservation and visible tracheids) but it can be reddish wood not lignitized or fragments of leaves. The first mention that I found is Monteil (1977) who indicates the discovery in a neighboring township of two leaf imprints of Otozamites sp. But this source isn't necessarily the most reliable because there are many inaccuracies or errors, but this is the only mention found this period and this area. So, for my own samples, this would be a flora from "wetlands", unusual for the french Jurassic (I believe that only one was found but a little younger, from the upper Oxfordian) and, more interesting, one (at least) of them was supposed to be Sagenopteris sp., a species of Caytoniales ("seed ferns"), never found in France. So here are the leaf imprints (or leaves) of some samples (normally the scales are correct but it is possible that I made a mistake). If someone has an identification idea or a suggestion I would be very grateful to him. 1a : Fern ? 1b 2 Fern with sporangia 3 ? 4 Fern with sporangia 5 Fern with sporangia 6 7 8 9 Fern with sporangia ? 10 Fern with sporangium 11 12 13 14 Fern ? 15

I found this today, I believe it is a smaller sample of one on a previous post. Someone thought it may be inner bark? I wonder if it is a leaf? The other image is the fossil on the same specimen, not sure what it is.

Fossils found in Florissant...

Went to the Florissant fossil quarry, and found some nice fossils. Wondering if I could possibly get them ID'ed, since I'm a novice. Thanks.
