Hello, I made a schematic of the Paleozoic the other day. schematic is probably not the right word for it but it's the best one I can think of, it's supposed to show the periods inside the Paleozoic and while not being perfectly accurate the idea of this thing is to give you a visual general idea of how long were the periods of the Paleozoic and some important events. It's not meant to be perfect but if I have any mistakes in the timeline I would love to know about them especially because my sources of information weren't great. I know it's not scientific at all and pretty poorly made, I am sorry if this is not appropriate to upload here because I know it's not directly fossil related. So as I said I would love to hear anything you have to say about this tiny project.

When was the Great Ordovician Biodiversification Event? (GOBE)?
Daniel Fischer posted a topic in Questions & Answers
Hello, I have a question about the great ordivician biodiversification events (GOBE). I know this series of events happened between the late cambrian and the late ordivician but are there more specific dates for it? For example like the great dying was about 250 million years ago. I couldn't find anything more specific then late cambrian to late ordivician but if you know something more specific or you know that there isn't a more specific date please tell me, I would love to know! -
Can anyone help ID these fossils given to me with no info on location/period?
TRexEliot posted a topic in Fossil ID
I prefer to find my own fossils, but over the years I've been given a handful of things by friends and family. Most of these were given with no accompanying information about the location where they were found or the geological age. I'd be very appreciative of any information people here can give.

Hello everyone, I recently got some fossils from Russia, some plant remains from Perm Krai where I grew up and a couple of Productid brachiopods from Sverdlovsk Oblast. They are from the Artinskian stage of the Permian period, one is around 2.5cm in width while the other even though incomplete is absolutely gigantic, the largest I have in my collection. I am not great at identifying Productid brachiopods and the Permian is probably the period I have least experience with within the Paleozoic so I have not been able to ID them myself. The large one looks similar to some Reticulatia sp. I've seen online but all of those are smaller so I don't know if that's accurate, the smaller one I have no idea. Thank you for any help, Misha

Can anyone help me identify these potential fossils that I found at Sunset Beach in Cape May, NJ?
Suchascenicworld posted a topic in Fossil ID
Hello everyone, I apologise in advance for the lower quality photos, my phone is quite old and the camera is going. Anyways, I was down in Cape May this past weekend and I decided to beach comb on sunset beach. i found several interesting items, and I was wondering if I can get some input regarding what they are. The first two images seem to be a similar type of fossil (if it is one). I am wondering if it could potentially be Paleozoic (if anything?). However, I am not sure exactly what it is, nor the material that it is made of. The third image I think could be coral, but I am not sure what type or how old given that it is out of context but any info would be appreciated. The last two images involve an interesting one. Now, for context, I have a background in Paleoecology and Taphonomy, and have had to id thousands of bones that date back as far as the Pliocene. While this could undoubtedly be a rock, (it always can!). However, for me...it really, really, looked like water rolled bone. In the last image, you can see that it is quite porous (in a way that looks more like cancelous bone) and the rock in itself is quite light. If it is bone, it would be quite old...but still, i am undoubtedly open minded that I could be wrong and it could just be a rock! What do you think? Anyways, thank you so much for taking a look!

I found what I think is a geode in a small stream here in Vigo County, Indiana. Brought it home and discovered all these unusual circular patterns along the narrower edges. Looks like urchin but I have not been able to find a similar type online. It does not feel hollow. Has anyone seen a similar surface patter on another specimen?

I've had these for close to 20 years now and have shown some of them before but figured it was time to do a proper job of looking for info. (If I did before, I can't find the topic) I know nothing about these, either ID or location. They were part of a batch of fossils I received from an old rockhound couple in Nanaimo, which wasn't too carefully curated (a common problem with rockhounds/casual fossil collectors). Looking for info on the mystery items from that lot is what brought me to the Forum in the first place more than 10 years ago. I know Riley's Canyon, Utah has red corals, but lately I'm seeing them from other places like Arizona also, so I'm not at all confident. It's a reasonable assumption that they're from somewhere in the US Southwest as it was (and is) common for rockhounds in our area to travel down there in the Winter for better weather and abundant rockhounding options, but that doesn't narrow it down much. Any ideas? Not all of them are preserved in red color, as you'll see below, so I'm not sure they're from the same place, but they were kind of bundled together when I received them. For reference, I'll number each pic. 1: The lot 2: 3: 4. Sliced end: 5. Sliced pair: 6. Some seem to be water-worn to some degree - these ones more so: 7. Is this a sponge? 8. Chaetetid? 9a/b. These are the ones that have little/no red, so I'm not sure if they're from a different location or just a different preservation from the same site: The larger piece is sliced. 10. This one looks different again, so it could be from a third site....

Sponge fossil from the late Paleozoic of southern Nevada?

Is anyone familiar with the Paleozoic formations on Bear Mountain, just northwest of Silver City, New Mexico? I have collected there a couple of times but am unsure as to which formation I was sampling. My first guess is that it is the Andrecito Member of the Lake Valley Limestone (Mississippian (Early Osage) but I know that there are also fossils found in the underlying Devonian Percha Shale, especially east of Silver City. There are a variety of brachiopods, bryozoans, rugose corals, and some crinoid bits. The photos show one of the larger brachiopods. Do you recognize it? Thanks.

This colonial rugose coral was found in Clarksville, TN and was sent to me just a few days ago and i’m not very well versed in Cnidarian classification, any ideas on a species?

After publishing some posts on this website it is time to introduce myself. My profession is teacher from west of Norway. As a child I lived in the western mountain each summer in a farm and liked to look at stones in a river nearby. I was very fascinated by the different shapes and colors of the stones. Unfortunately the area do not have any fossils, because the many glacier movements in the area crushed or removed any fossils in the past. But the area is very interesting when it comes to geology as the ladshape is formed by the collision betweeen Laurentia and Baltica in the silurian period and by the great Jostedal-glacier with beautiful hanging valleys and long fiords. The area has many sites with silurian rock which is clay slate or shales changed into phylite, used as a material for house building from ancient time. My interest in paleontology started just 2 years ago, when I began to see viseos and read articles about the subject. I have a master degree in philosophy and wrote a thesis about Aristotle's philosophy. Last spring when me and my friend drove by my car in the countryside north of Oslo, I was thinking of what I read in an article where a fossil hunter wrote that, "when i see a road-cut, I feel at once both sad and happy, sad because they destroyed a part of nature, but happy because i can see into the past". And there I did see a road-cut which seeemed to be a place with fossils. The rock was shales, clay-stones which was very easy to divide with the bare hands. After looking for just 3-4 minutes I found my first fossil, a big part of a trilobite. It was a beginners luck. Later I know the location is from early silur. After that I decided to become a fossil hunter. It was a perfect time to become a hunter in the beginning of corona time. I mostly seach in the Oslo field, where is camrian, ordovician and siluran formations. But this summer I went to the Bremanger area in west coast of Norway where there is 3 devonian formations pushed into land from the ocean. The formation I visited has sandstones in a high altitude, often above 1000 meters on top of mountains. There I only found one stone with some shells, but i hope to visiti the place again with ore knowledge of where to find fossils. I hope to learn more from other members of this forum of my own and others finds and also contribute what I can with my limitied knowledge. Here is a picture of my first fossil, the smaller part seems to be an extension of the bigger and the second largest from the opposite side. The length of the bigger part is 5 cm. I do nt know which species it is. Maybe some other member recognize that? Martin

I don’t know where it was found or how old was it is. I found it at one of the cave the mounds sleuthing sites in Dane county Wisconsin, its about 3cm long and looks a bit like coral.

This fossil was found at the North Attleboro fossil site, and I’ve had it marked down as a species of Sphenopteris but i’m not 100% certain

I was given this Eurypterid fossil a while back and I was looking to see if anyone had any ideas towards a species, i’ve got no idea where it came from other than somewhere in the New England/Canada area. Someone has told me it looks like an Adelophthalamus but id like some more opinions. Thank you
