From the album: Missouri Plant Fossils
One of my favorite finds comes in at roughly 2.8cm and has two beautiful leaves next to each other! -
I found this fossil in the north attleboro part of the rhode island formation, and I need help with an ID. It’s just shy of an inch in length.

A very small group of us ventured into the wilds of northern PA last weekend, equipped with masks and a permit to poke around a state wildlife preserve with Carboniferous Lewellyn Formation exposures. It was a gorgeous day and the colors of the limestone really shone in the sunlight. As we got there, a pair of permit-less fossil poachers were just leaving. How do I know that they didn't have a permit? Because they absolutely did not follow the rules. Since it is a wildlife preserve, it is important that anyone looking for fossils not leave craterous holes in the ground and replant any plants that were uprooted in the process of digging said holes. They left holes everywhere. Our intrepid permit holder filled in most of the holes so that she could keep getting permits in the future. For this reason, I'm not going to be any more specific about the location. That said, there were so many wonderful plant fossils to find! The site is remarkable for its red, orange and yellow limestone, which makes for some terrific, high-contrast fossils. Many of them had crisp details. What's more, there was quite a variety.

found this piece in a CP(early P or late C) stratum west of beijing, China, in which the most common stuff is neuropteris ovata. The vein is obvously neuropteris type, as can be seen easly under the sun, if not in the pic. The stem is about 5mm wide, which can be used as the scale. I have never seen neuropteris with this shape and size.

Conditions in Western PA have been unusually warm recently, with highs in the 40s and 50s. I decided to take advantage of this warm spell by getting a little bit of fossil hunting in. I decided to do a hunt focused on plants as I’ve been hunting for vertebrates for the better part of the last year and a half and, although I could never get tired of vertebrates I thought some variety was well overdue. So I headed to one of my favorite plant localities in the area. It is located in the Connellsville Sandstone of the Casselman Formation, which is in turn the upper half of the Conemaugh Group. The sandstone is around 305 million years old. The Casselman Formation holds the record of the tail end of one of the largest plant extinctions in our earths history. The prolonged wetness that had existed for much of the Pennsylvanian gave way to dryer conditions, and, as a result, the lycopsid forests fragmented. Many of these lycopsids went extinct during this event, which is known as the Carboniferous Rainforest Collapse. Conifers took advantage of these newly opened ecological niches. Their fossils have been found in this area, although I have never personally found them. Anyway, on to the fossils. Today I mostly found partial Pecopteris fronds, Neuropteris pinnules and Annularia leaflets. I’m going to include some of my better finds from other trips as well, as this trip was rather unproductive. Pictured below is the best Annularia I found today. Or Asterophyllites. I’m not sure. We’ll just go with Calamites leaves for now.

I had my first taste of the Carboniferous period. I made the trip to Centralia PA for a look at the fossils there. I went to coal deposit up the road from the cemetery on 2nd street ( pic below ). Centralia was not a "ghost town" not when I was there. There was a lot of people around. Many looked like they where their for the Graffiti Highway and other for some kind of four wheel event across the street from the spot I was at. The Shale was very soft and I had a hard time picking up anything bigger than 2 inches. I pulled away 3 layer but still had the same problem. I don't know if it would be them same if a kept going. Over all the sit was easy to find, and had a good view. With many fossil to pick from.

From the album: Massachusetts Fossils
Various Neuropteris sp. Found in 2018 in North Attleborough, Massachusetts. -
These were fossils my dad found over 20 years ago I think and gave to me maybe 10 yrs ago. I had completely forgotten about them. My dad use to be a land man for an oil and gas company. So he traveled the area extensively trying to get leases to drill for gas. I believe they are from somewhere near Mansfield, Arkansas from the Atoka or McAlester formations, both of which are Pennsylvanian. Any my help with ID would be greatly appreciated. First Piece The longest blade is about 55 mm long by 13 mm wide. A close up of some of the blades on the left side. I think there are 2 varieties here, not sure if the arching one is like the ones in the center and to the left of it. The center one is the top side of the blade and the one to the left and arching one appear to be the underside of the blades. It’s cool to be able to see that much detail. Then there is a different variety on the top left corner. I’ll take some close ups of those and post in a bit. A pic of the right side a bit closer up. I think in this pic there are at least 3 varieties of ferns. The ones on the top right pointing downwards which may be the same as those on the top left above. Then the long blade in the center running vertically. I think it is the only one of its kind represented on this plate. Then at the bottom running mostly horizontally. I have no clue as to the genus or even group of Medullosans. If I had to guess I’d say Neuropteris for all 3, but it’s a wild guess. Second piece is an Annularia of some kind I believe. You can se the long slender stems and then many long, slender leaves, which appear to have numerous veins running the length of the leaf. They are all cross crossing each other so it’s a bit chaotic to try to isolate one cluster. This is the back side. It has a couple stems running across it. There is more stuff in between layers on both pieces.

Neuropteris Leaf Rt 56 Bypass, Johnstown, Pennsylvania, USA Pennsylvanian Period (290-330 Million Years Ago) Neuropteris is an extinct seed fern that existed in the Carboniferous period, known only from fossils. Major species include Neuropteris loschi. It is a fairly common fossil in bituminous coal with Alethopteris and similar ferns, especially in the Carboniferous Alleghany Mountains of Pennsylvania, they can be found near St. Clair, Pennsylvania. One common leaf fossil found during the Carboniferous was once called Neuropteris scheuchzeri. In 1989, it was reclassified as Macroneuropteris scheuchzeri. This specimen looks like Neuropteris loschi Kingdom: Plantae Division: †Pteridospermatophyta Order: †Medullosales Family: †Neurodontopteridaceae Genus: †Neuropteris -
Can't help with the initial question but when checking the seller's offerings I just had to spontaneously buy a fern fossil as it looked so amazing and the price seemed also very ok! I've never bought a plant fossil before but also never seen a Carboniferous fossil which looked so well preserved and colorful to me. Oddly I can't find any of these anywhere else on the web and hardly any information about the locality. Does anyone have any information about the locality or the formation? Greetings from Germany

Multiple Plant Fossil - Neuropteris, Pecopteris, Annularia Plant, other leaves. *Two-sided fossil Ferndale area of Johnstown, Pennsylvania, USA Pennsylvanian - 323.2 -298.9 million years ago Fossils on both sides of specimen. This fine specimen shows two leaflets of Calamites, a member of the Calamitales which belong to the Sphenophytes. Whorls of small leaflets are arranged concentrically around a thin stem and are called Annularia or Asterophyllites. Calamites itself is the name originally given to a stem section, but now applies to the entire plant. These were indicative of humid to wet habitats such as along rivers and lake shores. There appears to be small "branches" of calamites as well. Also on this piece, Neuropteris leaflets - they are usually blunt tipped and are attached by a single stem as opposed by the entire base, like Pecopteris. Also, Neuropteris has an overall heartshape. Fern leaves called Pecopteris grew abundantly in the coal swamps of the Carboniferous Period. These leaves dropped off of a 35 foot fern tree called “Psaronius“, one of the most common Paleozoic types. With its sparse and expansive branches, it resembled the modern day palm tree. It produced as many as 7000 spores on the underside of its leaves. Kingdom: Plantae -

From the album: Cory's Lane, Rhode Island Fossils
Imprint of a Lepidodendron branch and Odontopteris reichiana pinnules. Found in 2016 at the Cory's Lane fossil locality, Rhode Island. -
I purchased this fern fossil some years ago from a rock shop in Colorado. It was identified as a Neuropteris sp. from the Braidwood formation, Johnson County, Missouri, from the Pennsylvanian period. I have several questions. First, when I do a Google search I see quite a number of fern fossils being offered for sale with the same provenance. But when I dive deeper, I can't find a Braidwood formation listed for Johnson County, Missouri. Here is the USGS listing of geologic units in Johnson County, and I don't see a Braidwood formation listed: https://mrdata.usgs.gov/geology/state/fips-unit.php?code=f29101. The only Braidwood I have found on Google is the Braidwood biota, part of the Mazon Creek fossil beds in Illinois. Has this been misidentified or am I missing something? Also, I'm not sure I can tell the difference between neuropteris and pecopteris species, can anyone give me a good identification? Thanks! 12X magnification: 25X magnification:

Here is another plant material plate I found over at Cory's Lane, Rhode Island. This medium sized plate has a lepidodendron branch going through the middle with calamites and neuropteris leaves around the edges of the matrix. -
With winter in New England fast approaching, I decided to spend the afternoon at Cory's Lane in Rhode Island. I found a number of Pennsylvanian aged plant imprints, but one plate of Neuropteris imprints has me stumped. This plate has a mystery object in it (A mystery to me at least). The long imprint going down the middle of this plate looks like an imprint of a stick, but I had thought sticks didn't preserve well in the Rhode Island Formation. Can anyone id the large, straight shaped imprint? Thanks!

Pittsburgh PA. I need to get a better camera.... The nodule (?) has a vein like pattern in it, and the other an area of perfectly straight lines. Hope pics are good enough to maybe ID. Also not sure if the second one is just an imprint.... Thought? http://www.thefossilforum.com/public/style_emoticons/#EMO_DIR#/smile.png

Fossil Plant - Neuropteris And Annularia - Mcintyre Mountain Pa
hitekmastr posted a topic in Fossil Hunting Trips
We collected these Neuropteris fern leaves and stems, and Annularia (Calamite tree) leaves at McIntyre Mountain in June 2012. This site is at the very top of the mountain, where the coal pits have been reclaimed and converted to a forested park. The veins of the leaves show up very clearly in the closeup photos.
