  1. Mazon Creek Fern ID Help?

    Hi again! I feel very fortunate to have such great minds helping to ID fossils here. I have one other Mazon Creek fossil that I would like some help with it. It’s a fairly large (5 inch) fossil fern nodule from Mazon Creek. My first question is, is this the common fern species variety Pecopteris? I think it might be but I see some variation within the leaves (that is the fern degree terminations). Is it unusual or rare to find ferns with them still attached to the plant stock/shaft from Mazon Creek? Last question, are the oriented dots on some of the ferns fossilized sporangia? I can’t find comparable examples like this online. Thank you!
  2. Large Pecopteris Found in Rhode Island

    From the album My Collection

    My current personal best from the Carboniferous aged shale of Rhode Island. A large, Pecoptertis sp. section.
  3. Plant!

    From top to bottom it is 5.5 cm. Leaf size about 2-3 cm depending on which you’re looking at. Area is Betteshanger, a Carboniferous area
  4. 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.
  5. Carboniferous Terrificous

    Here are some fossils I found in the town of St.clair in Schuylkill county , Pennsylvania. Llewellyn formation. 300 Mya. preserved in black shale.
  6. Pecopteris sp.

    From the album Cory's Lane, Rhode Island Fossils

    Pecopteris sp. Found in 2019 at Cory's Lane fossil locality, Rhode Island.
  7. I'm looking for opinions on this one..... I consulted a VERY old volume and found what I believe is a match... ESPECIALLY since the book's diagram was from my immediate area of Johnstown, Pennsylvania USA. This is from my Wednesday Feb. 21 hunt. The data on the fossil: Rt 56 Bypass, Johnstown, Pennsylvania, USA Pennsylvanian Period (290-330 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. (From A Dictionary of the Fossils of Pennsylvania VOL II:) Pecopteris velutina. Les. Geol. Pa. 1858, p. 866, pll. 12, fig. 3, 3 a; 3.from Johnstown, Cambria Co., Pa., venation not visible under the thick skin; but in a specimen afterwards obtained at Cannelton, Beaver Co., Pa., also with a thick shining skin some of the leaflets show the style of venation.Lesq.—Kittanning coal. XIII. Pecopteris is a very common form genus of leaves. Most Pecopteris leaves and fronds are associated with the marattialean tree fern Psaronius. However, Pecopteris-type foliage also is borne on several filicalean ferns, and at least one seed fern. Pecopteris first appeared in the Devonian period, but flourished in the Carboniferous, especially the Pennsylvanian. Plants bearing these leaves became extinct in the Permian period. 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 Species: †velutina
  8. Carboniferous tree fern

    Two days ago I bought this nice fossil for a very convenient price at a local shop. Unfortunately, the seller could not remember key informations about this specimen, but he told me that it probably was Pecopteris and came from Germany. I want to identify it for a proper display alongside my other Carboniferous fossils, but I need again some help from a more experienced collector. In my opinion it is very similar, if not identical, to an other Acitheca (Pecopteris) polymorpha specimen I previously identified on an old topic thanks to this wonderful community. It may be the same plant, but I'm not sure. I am also skeptical about its German origin, is it reliable? Here is the upper side of the fossil: Pinnules detail from the other side (not exceptional quality, but I tried to make them more clear with a flashlight) Thanks in advance for your help!
  9. Multiple Plants A.JPG

    From the album MY FOSSIL Collection - Dpaul7

    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

    Large Negative imprint of Pecopteris arborescens. Found in 2017 at Cory's Lane fossil locality, Rhode Island.
  18. 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 .
