Calamites *Note: Photo 1 & 2 show obverse; photo 3 shows reverse. Rt 56 Bypass, Johnstown, Pennsylvania, USA Pennsylvanian Period (290-330 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. Further organ genera belonging to sphenophytes include: (1) Arthropitys (stems which are preserved in a mineralised form (2) Astromyelon (permineralised rhizomes, distinguished from Arthropitys by the absence of a carinal canal) (3) Annularia and Asterophylites (form genera of leaf-whorls which are paraphyletic). This is possibly Calamites suckowi. Kingdom: Plantae Phylum: Pteridophyta Class: Equisetopsida Order: Equisetales Family: †Calamitaceae Genus: †Calamites -

Hello my name is Sbob I'm new to the forum and am looking for help ID'ing my fossil . Found in West Allentown Pa. in the 1970's . It's been sitting on my window sill for years , Finally got the motivation to ID it. My area was not know for any type of fossils of this type ,primarily Limestone leaving me curious as how it got there? . Found with other small limestone around approximately 2' below the surface . The fossildude19 will be helping me with picture post shortly , Thanks in advance

I found these in the creek back in September, this is the only pic I took (just now happened upon it in my files) and I can't find them to retake pics. The largest rock, the black one in the right of the frame, is no bigger than 2" at it's widest measurement, if that helps. I'm just really curious about what would make these little bubble-like formations printed on a rock like this. Bubbles?

This was a dig find

I have no idea, but it's small enough that good pics have been tricky and my curiosity has gotten the better of me so I am posting what I have. Can you give it a guess?

This is obviously not a seed fern fossil, but the "fossil guy" at the flea market across the river in Jersey told me that it is a fern. My understanding was that it is petrified plant material, a petrified fern. I'm not confident in his identification as he, I now know, missed several identifiable pieces (crinoid columnals and a chunk of perfect rose quartz, for example) or simply wasn't as into looking as he said he was. So, I need another ID! Again, as usual, it was found under the bridge behind my house in Bucks County, PA along the creek not far from the Delaware river.

The fossil I want most to find, at this point in my addiction, is a tullymonster. A few months ago, I thought this might be one, but, now, I'm fairly certain it's just a geode and am just double checking by asking for an ID. I actually really dig (that's so punny, lol!) geodes, so I'll add it to my collection, but I have enough criniods and brachiopods. I'm throwing a little tullymonster fit!

I can't figure out what this might be, I hope you can see it well enough. It was very hard to get good pics of the crushed side. I think it could be a crab shell, it's crushed but firm tho it seems slightly pliable and even breakable. It's not. The "mouth" seems to be more of a dent than an opening since sealed over and the perfect little circle on the top reminds me of a horseshoe crab. Some of the pics are color saturated to enhance the detail as best I could. Please, help, so curious!

Hi everyone! I’m not a collector or even a hobbiest (yet!) but I came across this forum looking for a way to start learning and to help me ID some interesting things I found the other day. I was walking with my dog in Cranberry Township PA (20miles north of Pittsburgh) and noticed a number of darker, reddish, oddly shaped stones that stood out against the hillside of crumbled gray shale that had been pulled out (possibly from as far as 50 feet down or so) in digging a drainage pit for a new development. Most of what I saw just looked like concretions formed around river stones or something like that (some were split in half so they almost resembled clams) but in one area there were pieces that looked different, some with fairly conspicuous tooth or bonelike shapes. I rinsed mud off of them with warm water and started scrubbing a bit with a brush but I noticed that the lightest areas on a couple pieces are fairly soft (I can scrape them with my fingernail) so I thought I'd better stop until I figured out what was what. I don’t really know anything about this stuff yet, but I loved looking for ferns, etc and even found a trilobyte once as a kid and so I was kinda thrilled to have maybe found something interesting. Of course, they could just be a pile of neat rocks too, haha... So what do you think I have here? Just organic looking concretions or something cooler? Thanks! (note: I embedded the images instead of directly attaching them, so if you click on them you'll be able to see higher-resolution versions)

This was found in Raubsville Pennsylvania it is not magnetic

Hello! I am David Ruckser, from Johnstown, Pennsylvania - An area with both plant and marine fossils. I retired a bit early; I have been retired for a year now! And I am busier than ever! I have many hobbies and collecting interests - In the late 1960s I was very interested in fossils. That interest has been rekindled! I hope to venture out in the spring again to hunt - I've made two forays into the field so far, and found some magnificent fossils - Sadly, they were on rock weighing well over a ton. In Springtime I will do much better! Some fossils I have found, or my sister in North Carolina has found and sent to me... I have bought fossils from commercial sites. One high school friend has a HUGE fossil business a few miles away - They were regulars at the big Tuscon show and Tokyo show. I will search a bit for fossils on my next Taiwan trip - I do think there are fossils there, will have to check. I hope to interact with new folks and share information!

I'm so happy to have found this place and feel that I may find as many people willing to help as I have mysterious and amazing finds! I'm excited to meet my neighbors and learn about our world from all. I don't even know where to begin!

There is excavation for a housing development behind our home. On examination of some large excavated limestone boulders, I noticed what appeared to be a cross-section of thoracic (rib cage) of a skeleton. I suspect it is a fossil, being that there is a noticeable pattern within the same layer of sedimentary rock. I've attached a picture, please note the rust colored protrusions within the blue-gray limestone boulder. Thank you for any input on whether my suspicions are reasonable. If so, I intend to contact the construction company as to the location of where the boulder was excavated, and whether they are agreeable to removing it from construction use.

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
