Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not just western PA but West Virginia and eastern Ohio as well.

I am attaching images of calamite and annularius specimens in my collection. Because their appears to be some debate among the experts on the relationships between calamites and sphenophyllum and asterophylloides, I am also including images of these specimens. I would welcome comments, suggestions or corrections from viewers. Further species identification would also be appreciated. Image 1 is of a Mesocalamite specimen that was among other Pennsylvanian fossils from Kentucky. Image 2 is of another Pennsylvanian Calamites from Kentucky. Image 3 is of a Pennsylvanian Calamites specimen from Alabama. Images 4 and 5 are Pennsylvanian Annularia leaf specimens from Mazon Creek IL. Image 6 is a Pennsylvanian Annularia radiata specimen from the Westwalian A & B, Lower Silesian in Poland. The contrast between the fossil and the underlying rock is so poor that I did alter the exposure settings in order to better view the fossil. Image 7 is of a Pennsylvanian Sphenophyllum specimen from Mazon Creek IL. Image 8 is of a Pennsylvanian Sphenophyllum cuneifolium specimen from the Westwalian A & B, Baszkirian, Lower Silesian in Poland. Again, because the contrast was so poor, I altered the exposure in an effort to obtain a better picture. Image 9 is of a Pennsylvanian Asterophylloides specimen from eastern Kentucky.

I have some fossil grass-like leaves from a specimen that was associated with other Pennsylvanian fossils collected from near Middlesboro, Kentucky. The specimen is somewhat problematic for display purposes because it has a very nice mesocalamite fossil on the opposite side. The 1st and 2nd images are of the leaflike fossils with a closeup. The white spots are apparently where reactive iron sulfides have been exposed to atmospheric humidity and were oxidized to some type of iron sulfate. The grasslike leaves do not appear to have a strong central vein which might suggest that these are cordaites leaves. The 3rd image is of the very nice mesocalamite fossil on the opposite side. Suggestions would be greatly appreciated.

One of a kind fossil from MA
spinoking27 posted a topic in Partners in Paleontology - Member Contributions to Science
Last week on Fossil Friday, the Museum of Natural History and Planetarium in Roger Williams Park added the fossil I found from my post last time and still proud about it because they said on their Facebook page that its only one they have in the collection . Because its the first of its kind I discovered around New England until I find more fossils around that site in North Atteborough just waiting to be discovered with a story to tell.

Both of these were collected in Grayson marl, is the small one a calamite? Hadn't occurred to me they could be found there. The larger one was 2 straight pieces side by side but the host rock is so fragile and part of top layer crumbled and broke them. Have not seen any burrows in Grayson so not sure if that's what they are.

Your Guess is Better Than Mine: Fossil Calamite? Scaled bark? Animal? ( Missouri )
Samurai posted a topic in Fossil ID
Location is in Missouri The area is dated to the Pennsylvanian Formation: ???? Hello! it is I once again I was curious on what this might be as it looks different from what I usually see in this type shale I have found Pyrite Calamites in shale but they usually don't have this texture so I was unsure of what exactly it may be. Zoomed in picture of the texture: Other side of this shale: Not Sure if these will help with the ID but here is the picture with the end pieces visible also for those interested here is the pyritized calamite I found near this: -

Good afternoon, I have submitted photos of this fossil to multiple local groups in hopes of a possible identification to no avail, therefore I have turned to this forum and home to figure this out! I hope it to be a calamite cone fossil but I have been wrong before, so I am asking for a second opinion. Thank you very much! Important information: This fossil was pulled off a shale cliff that is abundant in calamite and fern fossils. The cliff is located near Carnegie, Pennsylvania (Western PA). The specific fossil has both calamite and ferns on the reverse side. Edit 1: The size is about 1.5 inches (3.81 cm). Information that is possibly helpful but may not be: The cliff has a few layers of coal and black colored shale, while the majority of the cliff is a grey colored shale. This rock was pulled off just above a black shale line.

I know these two are Calamites but I’m unsure how to identify the species. They were both found in the North Attleboro part of the Rhode Island formation and I’m thinking the larger one is C. Cistii?

One of my favorite Calamites due to how well preserved its internal anatomy is! I gave this to a friend's little brother who loves fossils. -
I picked up two additional fossils I needed. First one is a Calamites Leaf Tip, needed this to go with all my other Calamite fossils. Second is a Lepidodendron Leaf , I only had one small sample of this so wanted more. this is all Pennsylvanian age

This was found in Hamlin wV in a layer of sandstone approx 614 ft above see level it looks to be calamite but the needles or whatever you call them around the stem seem to close together. Theres a pop bottle cap up top for reference to size or whatever u call it Soda bottle cap in your area of the country. This came from my back yard theres a rock outcrop at the base of this hill and every square inch of this rock is smashed plant material like it was a leading edge of a flash flood how it carrys all the plants trees and trash that it picks up in that thick slurry cause 10 ft up and 20ft over theres nothing but mud notice that hollow stem there on the right

This was given to me from a third hand source. I’m only assuming it’s from Illinois—I really don’t know. I supposed it was a calamites horsetail, but I’m seeking confirmation before I catalogue it. Anyone?

Calamite Tree Fossil SITE LOCATION: eastern Kentucky TIME PERIOD: Carboniferous, Pennsylvanian Period (330 million years ago) Data: Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related. Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of more than 30 meters (100 feet). They were components of the understories of coal swamps of the Carboniferous Period (around 360 to 300 million years ago). A number of organ taxa have been identified as part of a united organism, which has inherited the name Calamites in popular culture. Calamites correctly refers only to casts of the stem of Carboniferous/Permian sphenophytes, and as such is a form genus of little taxonomic value. There are two forms of casts, which can give mistaken impressions of the organisms. The most common is an internal cast of the hollow (or pith-filled) void in the centre of the trunk. This can cause some confusion: firstly, it must be remembered that a fossil was probably surrounded with 4-5 times its width in (unpreserved) vascular tissue, so the organisms were much wider than the internal casts preserved. Further, the fossil gets narrower as it attaches to a rhizoid, a place where one would expect there to be the highest concentration of vascular tissue (as this is where the peak transport occurs). However, because the fossil is a cast, the narrowing in fact represents a constriction of the cavity, into which vascular tubes encroach as they widen. The trunks of Calamites had a distinctive segmented, bamboo-like appearance and vertical ribbing. The branches, leaves and cones were all borne in whorls. The leaves were needle-shaped, with up to 25 per whorl. Their trunks produced secondary xylem, meaning they were made of wood. The vascular cambium of Calamites was unifacial, producing secondary xylem towards the stem center, but not secondary phloem. The stems of modern horsetails are typically hollow or contain numerous elongated air-filled sacs. Calamites was similar in that its trunk and stems were hollow, like wooden tubes. When these trunks buckled and broke, they could fill with sediment. This is the reason pith casts of the inside of Calamites stems are so common as fossils. Kingdom: Plantae Phylum: Pteridophyta Class: Equisetopsida Order: Equisetales Family: †Calamitaceae Genus: †Calamites-

calamite seems to have many layers of bark like onion?
jeromebe posted a topic in Questions & Answers
It might be hard to see from the pic. But looking at the calamite fossil I found, it appears that it had many layers of bark. It almost seems like it had many layers of skin like onion. I know these tree would get up to 100 feets or so. I was wondering if anybody knew if it had diffrent layers of bark? -
So got out fossil hunting for a couple hours today in Washington, PA and found some new stuff, some better examples of previous finds, and a lot of the same... Some of which I still had to pick up but didn't go overboard... lol. I would like to start with something I picked up on the way back to my car. First one of its kind I have found at this site. Thoughts? In trying to adjust my eyes for more 2 or 3D plant fossils I found these. The second I have found a similar piece of in the past that was ID'd as an inner layer of a plant fossil. This is a new piece so welcome to any new thought on that or this other one... More to follow...
