From the album: MY FOSSIL Collection - Dpaul7
Pecopteris Fern Fossil From Pleasantville Mountain, Somerset Co., Pennsylvania, USA Pennsylvanian - Carboniferous (323.2 -298.9 million years ago) 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. These samples are well preserved in gray coal shale as many Carboniferous leaf fossils. Kingdom: Plantae Phylum: Pteridophtya (meaning vascular plant with transport system for nutrients and fluids) Class: Filicopsida (Ferns which reproduce with spores) Order: Marattiales (primitive ferns) Family: Marattiaceae Genus: Pecopteris -

In between all of the 4th of July weekend barbecues I was able to make it down to Cory's Lane, Rhode Island for a few hours of shale splitting. The day started out slow with only a few small plant imprints found, but I eventually managed to rip up a 5 foot slab of rock with a larger fern section on one end of it. After cutting the slab down to a little over a foot and a half in length this Pecopteris arborescens manages to go down as the largest fern I've found at this locality! It was a nice start to the long weekend, but the real win was the awesome weather .

Positive and negative imprint of Pecopteris arborescens. All that was left of the negative imprint was a small mid section of the fern. Found in 2017 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:

Hello everyone, I've some questions about this Pecopteris fossil (pic 1) from the Carboniferous of France. On the other side (pic 2) there are other leafs. Can you help me identifying them ? Thank you

Here is the negative and positive imprint of a Pennsylvanian aged fern that I found. This fossil belongs to the Pecopteris genus. Found at Corys Lane, Rhode Island. -
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.

Hi. I'm Ben. I'm revisiting the interest I had in fossils and rocks as a kid. A few months ago I was out adventuring with my camera when I found a small fern fossil. I immediately started to search for more but that was the only one I found. With a little research I found out it's probably a pecopteris. Here is the fossil (with cashew for scale).

From the album: Pittsburgh Fossils in Handmade Museum Boxes
I believe this specimen would be pecopteris? approximately 300 mya. Collected in Rennerdale, PA. Approximately 3 inches in length. It is housed in "museum" box I made with two modern fern fronds which were preserved with a special oxidization-inhibiting sealant. -

These fossils are from our second visit to St. Clair (Aug 4) - several are fossils we haven't seen before so we appreciate help with IDs. Special thanks to Fossildude19 for the excellent starting points. Note: some of the images are out of order when you look at the photos below, because I am renaming and reposting them as they are being identified: 1 - Pecopteris Squamosa - This is small and the leaves are very close together and parallel - based on Lesquereux - amazing that some of the best fern identification sources are from 1879! 2 - Calamites Stem Fragment - A thin Calamites branch. 3 - Unidentified Plant - Nancy calls this a "flower" - of course it isn't, but it seems to be a different shape from others we collected at St. Clair. 4 - Alethopteris and Annularia - Included this because it makes for a nice artistic layout. 5a-5b - Asterophyllites equisetiformis - This interesting pattern appears over a large area several meters square in one part of the St. Clair site, and covers the surface of a very large flat boulder in one area of the site. (source: 6 - Siggilaria - This is our second Siggilaria trunk impression. Some of the trunk and branch fossils (Calamites, Siggilaria) are very exotic and interesting to collect. 7a-7c - Trigonocarpus (Seeds of the Alethopteris Fern) - The same shape appears in three different samples collected on our two trips and according to our friends on the site and reference materials, they appear to be Trigonocarpus seeds, which is very exciting because we keep reading about seed ferns but these are our first fossil seeds. One reference describes Trigonocarpus as the seeds of Alethopteris (which is the most common fern found at St. Clair) - other sources give these the nickname "fossil pecans" because of their physical resemblance. 8a-8b and 9a - Cyclopteris - Fan Shaped Leaves - Some of the reference books show round fan shaped versions of some common ferns but this looks like something separate so we're going with Cyclopteris. We'll try to find a separate, more articulated sample on a future trip. 10 - Unidentified Fern. 11 - Assume this is Sphenopteris. 12 - Assume this is Neuropteris - Where Neuropteris sometimes has rounded leaves (??) 13 - Sphenophyllum - Including just for fun. I'll update the names in this list as the IDs are confirmed. One of our goals continues to be, finding scarce specimens we haven't come across yet, as well as articulated fossils, designs and larger pieces for display. As you can see, we're already making great headway identifying these. Thanks to everyone who helped us ID our finds in the past 2 months, and especially for helping with these...we're really surprised how many different species there are at this single site, all very close together.
