I am not always able to understand when I am looking at a sponge. Thx in advance.
-
I have a lot of coral but none like this one. I don't know whether it's size is the result of the fossil process or coral type. It's 3.5 cm tall; circumference is 12.5 cm.

Is this an echinoderm?
-
I was wondering if this might be a plant fossil, or is it an imposter? Found in Kosciusko County, Indiana. Silurian? Devonian?
-
I am wondering if this sample is a trilobite. The second pic contains an additional sample. Both taken from the same rock.

I was wondering about this pattern. Thx.

This is a macro shot of a samples measuring btn 1/8"-1/4". I was wondering if it's coral.

I pulled this from the creek and wanted to know if it has enough information to posit an ID.

I am looking for help in making accurate IDs of some fossils from northcentral Indiana, wondering if they are bryozoans. All are approx 1/4"-1/2".

Hi all, first post here. Central PA, Slab from roadside float from Mifflintown-Bloomsburg (undivided). A thin layer contains a lot of small (1/16" dia), flattish fossils that I think might be inarticulate brachiopods. I have a number of specimens from other parts of the exposed layers and these do not appear in any of the others. One old paper on this formation mentioned "inarticulate brachiopods". I'm new enough that I didn't know about the articulate and inarticulate division in this group, so I'm already learning stuff. Awesome. Googling some pics returned some images that kinda look like what I have. But not quite. What do you think? If not inarticulate braichiopod, what else could they be?

Central PA, Mifflintown-Bloomsburg (undividied) Block collected from roadsite float. Its pretty variable, with a flaky/fissile layers alternating with slightly more cohesive ones. Lots of broken brachiopod bits. For an experiment to I dropped an unremarkable flake the size of a large coin in some vinegar and let it soak for a day. The flake had a couple brachiopod bits and I wanted to see if they would fall free or dissolve in place. The brachiopds disappeared and I was left with this (see pics). Of course I got really excited and thought I had an early fish spine, but now I think I dissolved a crinoid stem and what we see is the matrix that filled in the soft bits. What do you think? Total length is 3/4"

Much of this past week has felt less like a winter break and more like a switch from school work to government work. It seemed like many a day this week slowly chugged along, clogged by bureaucratic paperwork, followed by some bureaucratic paperwork, topped off with...more bureaucratic paperwork. As I'm sure many of you can understand, this left me a little restless. Having only the internet to provide you much of any entertainment will only last you so long. Thus, I decided today would need some much-needed paleo zest. A couple of days back I was scanning through Fossil hunting videos on YouTube, looking for new things to do (or watching the Ditch Weasel's Megalodon tooth hunting videos for the billionth time). Then I came across a video I hadn't watched in a long time, about a mysterious GA site I had never been to before. With a quick look in the description and comment section, I learned that it was near Dalton. With this in mind, I Googled "Dalton Fossils". To my surprise, the first result was a trip report @Nimravis wrote a little more than a year ago: With GPS coordinates now saved to Google Maps, My step grandpa and I headed out, partly guided by my phone's robotic voice. We arrived at the site, greeted by a thick fog: I put on waterproof boots, grabbed my hammer and chisel, and crossed the street to begin my search for Silurian treasures from the Red Mountain Formation. When we crossed the street, going around the leftmost portion of the wall (parking lot perspective), We heard a rustling off to the right. A decent sized Boulder slid down from the top of the hill, taking a decent chunk of dirt with it. In the end, it was a relatively small event, but we kept an eye out in case of other potential instabilities in the rock face. At entrance, facing the direction the mine lankslide occured Full attention on finding fossils, it didn't take very long at all to find some brachiopod plates.

Fossils on Wheels received another generous donation to our education programs this week. TFF member @Herb sent us a box of super cool invertebrates. He sent us a diversity of fossils from the Southern US that cover a wide range of eras. These fossils will be given to students in fossil starter kits and used in hands-on activities. Herb's donation is also awesome because this pushes me to learning a lot more about invertebrate fossils. One of the best parts of teaching kids about natural history through fossil exploration is that I get to learn a lot. Good teachers learn and challenge themselves so they can challenge their students. I do not have a lot of knowledge about these types of animals but I am so excited to start learning. Among the fossils we received were- Mississippian Corals and Brachiopods from Kentucky, Crinoid stems and Silurian sponges from Tennessee, Cretaceous Gastropods from Texas, and Eocene Bivalves from Alabama. Thank you Herb for a generous donation that will get put to good use

A little Lower Silurian Collecting in Dalton, Georgia
Nimravis posted a topic in Fossil Hunting Trips
Today I made a quick stop on Dug Gap Mountain Road in Dalton, Georgia and did a little collecting in the Lower Silurian Red Mountain Formation. At this location you find imprints of shells, though I cannot find any information on them.

Hi, I have another mysterious fossil. Silurian. Ostracod? Any ideas? (Bottom right): Side View:

HI, Curious what this could be? It measures only 1mm found in Silurian deposit northern Illinois embedded in matrix along with pelecypods and gastropods. It looks like it could possibly be a tiny shark tooth, but I don't know anything about shark teeth. Are teeth ever found that small? At first thought maybe conodont but doesn't really have the caramel sheen to it. Any ideas? Any help appreciated.

Until I am able to start a Gallery Page I am going to fetaure some of my Waldron Shale specimens. Featured here is one of only a few known specimens of a complete Eucalyptocrinites crassus complete with root system. I collected this specimen near the type locality in Shelby County, Indiana. I prepared 90 percent of this specimen with some final matrix work being done by Scott Vergiels. Specimen measures 8 inches high.

Hello, I can't seem to ID this fossil found in Silurian reef rock, Chicago area. I made some slices. Any help appreciated.

Coralline red algae from the Silurian of Gotland is much older than previously thought

Okay, this is way, way out there, but it's a maybe. I am sitting on the fence for going real or mother nature. I was strolling around the mountains today. On an Silurian plateau I spied this piece of cherty material with what may or may not be a small crinoid. It is a bit banged up, kind of rusty looking, but seems like an immature crinoid??? Otherwise, a very interesting want-to-be. Material is missing from some areas which would have been helpful and it wraps around the edge of the rock making it challenging to photograph. On the entire chunk of rock there are no other features of note. Size from 8 on the ruler as it wraps around the other side comes out to about 35mm
