From the album: Cephalopods Worldwide
4cm. A slice through the middle of a goniatite from Winterberg quarry near Bad Grund in Harz, Lower Saxony, Germany. The stratigraphy is interesting. Although the micrite sediments in which they and other fauna were found are early carbiniferous, they were deposited in a tectonic fissure within the local devonian reef limestone, which made for a bit of riddle work when they were first discovered. Below is another one of them.-

A very common genus, ranging from Ordovician to Upper Carboniferous to ?Permian. This specimen shows good internal detail of the narrow corallites (1.2 - 1.5 mm), including septal spines which are not diagnostic and may not always be present (this may be preservational). The long, infundibuliform (funnel shaped) tabulae are characteristic and show in some of the longitudinal sections. Scale bar 1 cm long.

Hi! I just recently found this piece for sale, with no identification. The bumpy texture made me think of Arthropleura, but could also be something like a Stigmaria root. Please let me know what you think!

A second large Clam or Oyster? I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer so that I could actually pick pieces up. After the heat this weekend, they were easy to pick apart once I got them home. Yesterday, I found the first piece. This is the one I found today. When it came out of the rock I was a bit shocked at how large it was. I carefully tapped around the specimen and was able to remove most of the surrounding rock carefully. This is the larger of the two pieces I found this weekend. I have less confidence in identifying it as has less features than the first piece. You can see shell material flaking off in the 3rd and 4th photos below. The fossil after I found it: Then, once I removed it from the rock:

I love and hate finding large fossils. They are really interesting and striking to look at, but I have a hard time getting an ID on them. I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer. After the heat this weekend, they were easy to pick apart. Yesterday, out popped this piece. There is another one I found today that I will be posting after this one. This piece has several wavy ridges. The shell material looks pearly, and perhaps some calcite replacement has happened. There was a piece of shell stuck on the mold portion as well. I'm seeing about 6 distinct ridges. Anyone know what it might be? Before I removed it from the rock: Several views after removing, trying to show the ridges:

fossils and minerals/vs carboniferous
fifbrindacier posted a topic in Member-to-Member Fossil Trades
Hi everybody. I friend of mine entrusted me with his fossils and minerals because he wants to make tradings against carboniferous items. If you have coal to trade he'd like something with a mineral Inside (he's from the north of France, so he has plenty of coal). Please, PM me your proposals, i'll show him your photos.

5/13/19 Oglesby, IL Roadcut- Pennsylvanian shark bits, brachiopods and more
deutscheben posted a topic in Fossil Hunting Trips
A week ago today, I took the day off work to hit one of my favorite sites, a roadcut above the Illinois River in Oglesby, Illinois. This cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation and produces abundant brachiopods as well as occasional other fauna including gastropods, cephalopods, coral, trilobites, and shark teeth. The weather was perfect, sunny but not too warm, when I pulled up. The cut is a somewhat unstable slope of cobbles and boulders of varying size, almost all with at least some fossils in them. To get up to the slope, you have to hop across a small ditch with running water. I have a good sampling of the common brachiopods from here, so I am looking for unusual fossils when I go now. I was very happy to quickly find a piece of trilobite as I started to search the rocks at the base of the hill. (I will put pics of everything I brought home in a response post) One interesting find that I was not able to bring home was this Linoproductus brachiopod with some shell preserved and a really pretty dendritic pattern on it- it was very delicate and firmly embedded in the middle of an ~80 lb boulder. I was able to stay for 4 hours, and I felt like I gave most of the site at least a quick look. I am very happy with what I found- I was able to check off many of the rarer things I was looking for, including shark teeth, a trilobite, cephalopod material, and a brachiopod with spines attached, as well as some nice crystallized brachiopods. I will post all of my finds below.

@piranha @GerryK Can anyone confirm this is Paladin transilis? I found this in the Carboniferous of Illinois. Not sure if they've ever been described here...... And yes it's preserved in pyrite.

Tonight I found a new limestone ledge sitting 6 inches from a stream water level. My father and I started hammering away at the shallow edges and removed a ton of interesting specimens. While there were some nice cephalopods, lots of brachiopods and clams, this piece caught my eye. I’ve read about Bryozoa and I’ve seen similar things on fossil plates. I believe I remember seeing pieces of them in limestone while digging, but never anything big. So, is it a Fenestella? Or something else? I’ve never found one worth showing. I saw a species list for it and it is very long.

Two mystery mini fossils. I’ll include scale photos, with marks at 1/2 mm. I’m on the lookout for Carboniferous Trilobites, and examples I’ve seen are very tiny in this formation, no more than 1/2 inch long.

This head spine has just reappeared in my collection - I must have found it about 20 years ago in Linton. Is that an Orthacanthus or Xenacanthus head spine? The length is about 8 cm / 3". Thanks Thomas

Help Identify. Petrified Wood? Petrified Cactus? Something else?
SCSeaGal15 posted a topic in Fossil ID
Found this antiquing. Was only marked "petrified rock"..It is black & charcoal gray in color with a vertical ribbed texture and some rounded ends. Measures 6.5" tall x 5.5" x 4" and weighs 8lbs 1.1 oz. Is it petrified wood ? Petrified cactus? Or something else? It's only letting me upload 1 photo. Took pics with phone and guess their too big. Will try to post more.

I’ve just joined and am looking for some help identifying some fossils I’ve picked up over the years. Trouble is I can’t remember where I found some of them. A neighbour told me his kids were interested in fossils and I was going to give him a box of mine for them to keep but they’re quite young and may be baffled by them unless I can give them a name so they can look them up and find out some more for themselves. I’ve spent hours being amazed by the information in the members’ galleries and learned quite a bit about some of the fossils but I’m still stumped by several. So I’ll take some good pictures and post them up later and any advice would be really gratefully received. I did study geology and fossils as a small part of my education, but that was soooo long ago that I’ve forgotten most of it now. But I just love finding stuff! And knowing what that stuff really is... makes it so much more intriguing.

One of my first exciting finds was a piece that looked like a tooth back in March. Turned out to likely be just a cool shaped rock. Fast forward 3 months and I finally found this today, which I believe is an actual tooth. But I'm no expert, is my identification correct?

I've recently become aware that there has been Pennsylvanian plant material found in the vicinity of Lansing, MI (Saginaw Formation I believe). All academic papers I've found on the subject are quite old, and I've read conflicting reports from here and other websites as to whether these localities are productive at all. Has anyone had experience hunting these areas?

Yesterday i found a very rare Megalichthys jaw with dozens of teeth still attached in the Carboniferous of Illinois, USA. This is possibly the best known example of this fish found in Illinois. Not sure yet though. I still need to do more research. You can see four larger teeth in cross-section on the matrix waiting to be prepped out. Then there are smaller teeth in-between the larger ones, maybe 4× smaller. I also found several large scales. I'll attach the best one. All of this material still needs a proper repair and prep job. The preservation on this material is just stunning. I'm not sure it could get much better. These bone fragments and scales are often found with Orthacanthus teeth and Calamites. So it gives us such a beautiful snapshot of the environment at the time. Just awesome! Happy hunting

Hi! Here is a trip report on visiting a locality near Carlin, Nevada (one of our early videos). I'm not sure if what we decided to call "octopus beaks" (see 1:44 and image attached) are the real thing and not just fragments of brachiopods. Perhaps, somebody more knowledgeable can weigh in with the right answer. Thanks in advance!

Went looking on a old pit spoil that is slowly giving up it's nodules,the site is in the British coal measures of Derbyshire as with Mazon Creek it is well overgrown but the nodules here are not easy to find ....Yet! These are 2 nodules from the spoil that i'm sure will one day give up it's treasures. Asterophyllites sp Lycopsids Cheers John

I'm wondering if there are any Carboniferous coal deposits that are in the north east of England, I've been to seaham and found some nice plant material but I'm wondering if there are any other locations where nice plant material can found in the Durham area?
