I am attaching photos of Sigillaria fossils in my collection. Members of the Forum have been helpful before and as always, suggestions/comments/corrections are welcome. The first image is of a Pennsylvanian Sigillaria syringodendron specimen from Czechoslovakia. The second image is of a Sigillaria specimen from the Pennsylvanian in Eastern Kentucky. The third image is a Pennsylavanian Sigillaria specimen from the Westphalian in Czerwionka, Poland. The fourth image is of Pennsylvanian Sigillaria leaves from Podrovskoe, District of Donetsk Region, Ukraine. The contrast is poor but these leaves do have a remarkable similarity to grasses (although grasses did not evolve until hundreds of millions of year later). The last image is of a Pennsylvanian specimen from Kentucky that was identified by a helpful Forum member as a Sigillaria cortex specimen.

Went to a site in central PA today and collected some Llewelyn formation ferns and other Carboniferous plants. Second opinions on the following are appreciated! 1, I thought this is an Alethopteris but the leaves look like they can also be some immature Neuropteris with compound leaves with the leaves pressed together. 2. Is this Sigillaria bark? 3. Wasn’t sure if this is Lepidodendron bark. These crosshatched stem-looking prints are quite common at the site 4. is this a Calamite print? 5. I am fairly certain this is Neuropteris but just would like to be sure. That’s all. All and any help is appreciated! Thanks in advance and let me know if scale is needed.

Blair County Pennsylvania (USA) (Private property) ..... Recently I explored some heaps of old mine talus which I think is the whitish sandstone from the Pottsville Formation. These rocks commonly have imprints in various degree of detail, especially cordaites and lycopods. The pics below show one large boulder with what I think is a very large imprint of sigillaria. The tape shows 8 feet. I'll readily admit that I'm a noob and susceptible to seeing what I want to see. From my pics someone who knows 'way more than I will ever learn opined the "ridges" are really geochemical in nature. I think they were implying that being mineralogically different they were more resistant to erosion. I'd like to learn more about what to do to followup, and try to verify one interpretation or the other? FWIW, I can't help but think of how I've never seen similar ridging in this formation, assuming I correctly identified the source as Pottsville formation sandstone. There's a lot of this material in Blair/Cambria old mine areas. The leaf scars, if they're there, don't show up in great detail. But then again, I have much smaller samples where you can see leaf scars clearly on one part of the rock and they fade out in another. The pics below are either from early morn and noon, so sun is at different angles. The way I read this rock, the cast is more or less lying in the bedding plane, and there is a calamites along one side. Short of microscopic or chemical analysis in the lab, is there anything more I can do in the field to help firm up an ID one way or the other? Very consistent Some exfoliation allowing a peek at a cross section A Calamites (sp) next to the maybe-Sigillaria Exposed back and back-right corner of boulder, trying to get an idea of bedding planes (This series of three starts at the back side and moves around to the left as we face the rock Is there something else I could do or look for when I return, to help verify its either a Sigillaria imprint, or a (boo hoo hoo) another "Foss-iLarm"?

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.

I found this in a stream bed yesterday in Preston County, WV. There are several tree fossils in the area, but this is my first significant find in this location. It was sitting in the bank erosion/water line of the stream. From my amateur sleuthing, I found similar pictures of sigillaria fossils. Not the typical bark pattern though. Thoughts?

Hello and thank you for your input. This slab is 20" x 15" and has a folded, what I believe to be a sigillaria leaf that is about 30" long. I am not sure though? I have color changed one of the photos so you can see the specimen in the center.

From the album: MY FOSSIL Collection - Dpaul7
Sigillaria Tree Fossil SITE LOCATION: Eastern Kentucky TIME PERIOD: Carboniferous, Pennsylvanian Period (307-331 Million Yeas Ago) Sigillaria is a genus of extinct, spore-bearing, arborescent (tree-like) plants. It was a lycopodiophyte, and is related to the lycopsids, or club-mosses, but even more closely to quillworts, as was its associate Lepidodendron. This genus is known in the fossil records from the Late Carboniferous period but dwindled to extinction in the early Permian period (age range: from 383.7 to 254.0 million years ago). Fossils are found in United States, Canada, China, Korea, Tanzania and Zimbabwe. Kingdom: Plantae Phylum: Lycopodiophyta Class: Isoetopsida Order: †Lepidodendrales Family: †Sigillariaceae Genus: †Sigillaria-

Would anyone have any sort of idea of how much this Stigmaria fossil might be worth? It is approximately 12 in. x 6 in., I do not know where it originally is from. It was found within the landscape rocks of my sisters house, which is in southwest Ohio. From what I know of these, they are Carboniferous and not typically found around here, since most of the fossils found here (Cincinnati, OH) are usually Ordovician. I was thinking this stigmaria might have been transported with rocks from a quarry for landscaping purposes. The house is over 50 years old, so I have no way of knowing where the rocks came from. I was thinking of offering my brother in law something for this fossilized tree root (He does not collect fossils by the way.) What would this stigmaria be worth to someone who collects fossils like me? Thanks to anyone who replies, your opinions will be appreciated.

Looking back at one of my older "fossils" - Distorted root or siderite nodule?
icycatelf posted a topic in Fossil ID
Among my first posts here was a piece that I initially thought was some kind of coral, but those who reviewed it thought it may have been Lepidodendron Stigmaria, although still puzzled by its appearance. After countless times of looking it up, I've yet to see any Lepidodendron fossils (root or not) that look quite like it. I was reading up on fossils again recently and came across another Pennsylvanian fossil (related to Lepidodendron) that, in my opinion, looks far more like my specimen. Do you guys think it may instead be Sigillaria? Attached are some examples. EDIT: Close-ups added later in topic (post #9). Edge close-ups in post #26. -
Dear Forum, All six of the following photographs show Sigillaria fossils. But what species? I know there are a couple of lycophyte specialists here on the forum, and any help with identification is much appreciated. All specimens were found in the Westphalian (Upper Carboniferous) of Belgium or the Netherlands. Scale bar = 1 cm (all images). So far we have: 1 S. mamillaris 2 S. 3 S. 4 S. 5 S. boblayi 6 S. tesselata Kind regards, Tim 1 2 3 4 5 6

Very Interesting "mutation" In A Peice Of Carboniferous Bark... Help!
pecopteris posted a topic in Fossil ID
Here is one of my newer plant fossils from Poland. Sigillaria bardii sp. What is with the weird deformed part of the bark in the middle of the specimen? Can anyone elaborate? Is it the end of a growth cycle or somthing? Thanks, Peco- 35 replies
