A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

Howdy all, Found this Vinlandostrophia last year near the end of the warm season and decided to make it into a necklace without first identifying the exact species. I'm guessing it's a rarer flavor as this is one of two angel-winged vinlandostrophias I've found in my four years of hunting the Drakes Formation and out of the hundreds of vinlandostrophias I've found.

Howdy all, Found these in my usual spot in the Drakes formation. The first two look like some sort of bivalve, not a brachiopod. The second looks like some sort of coral.

Howdy all, This is something I've wondered for a while. What is the relationship between the Drakes and Kope formation and what are the differences?

Howdy all, Been finding some crinoid stems in my usual spot in the Drakes Formation and I'm wanting an ID on them. They look similar to stems from Agaricocrinus americanus from the Carboniferous of the eastern U.S., though they were found in an upper Ordovician deposit. Any ideas?

Howdy all, I've been wondering about this piece for a while. I picked it up thinking it was just a strange rock but someone said it was a worm burrow. What do y'all think? (Found in the Drakes Formation of Louisville, Kentucky).

This is a molt fragment of Isotelus sp. that I found in the Drakes formation in one of my usual spots. I've found isotelus pieces before, but this one is odd to me. In particular, I don't know what the lines on it are (not the cracks, I have the lines I'm talking about outlined in the pictures). I thought they might be a possible injury but I'm not sure.

I've been fascinated with Aegirocassis for a while now. The fact that a complex, giant filter feeder occured so many millions of years ago astonishes me. Its just such an alien animal. I've found little fragments of arthropod molts in the Drakes formation which belong to Isotelus. That got me wondering. What are the chances that instead of these all being from isotelus, that they're instead from another arthropod such as a eurypterid or ordovician radiodont. Another question I have is, does aegirocassis or a radiodont related to aegirocassis occur in any places other than morocco. The Drakes formation seems to have experienced a submarine landslide (don't quote me on this) and most to all of the fossils there are of creatures that were overtaken by said landslide. (Not entirely sure if this is true) But, what if there were such radiodonts like aegirocassis living in the Drakes formation but the only fossils we would find of them is molt fragments like the ones I've found that fell off of the animal and were buried in the sediment, instead of whole body fossils because they were able to escape this landslide. Though, I suppose the only way to confirm that such a radiodont lived in the Drakes would be to find an actual fossilized corpse of one. Really I just think this is a fun idea but it definitely would be cool if it is true.

I found these two pieces in the Drakes formation of Louisville, Kentucky a little while ago. I'm 85% sure that these are molt fragments from Isotelus maximus but needed a second opinion. One could argue that these are simply iron coatings on pebbles, but if you look at the second one, the "coating" dips down into the pebble, and is also mixed in with a few other fossils such as vinlandostrophia. Then again I could still be wrong, I have been before.

I found several remains of an orthoconic nautiloid yesterday while hunting in the Drakes Formation. I was showing it to @FossilNerd and he was unsure if it could be from the Ordovician Drakes Formation, or if I found it where the Drakes overlaps with another younger formation. Is there anyone who knows of such a formation or if this is indeed an Ordovician nautiloid? If it is Ordovician, that would most likely make it Endoceras, as this is the only nautiloid that I have found to have some kind of record in this area. The area in particular of the Drakes Formation is the Bardstown Reef. Here's some websites I frequently use to identify things from the Drakes. https://www.mindat.org/paleo_loc.php?id=19139 https://www.uky.edu/KGS/fossils/fossil-kinds-found-in-ky.php

I've found a few of what looks like remains from a trilobite or some other Ordovician arthropod at the Drakes formation in Louisville, Kentucky. Is that what these are?

I found this death plate during one of my hunts in the Drakes Formation and am unsure if it is Rafinesquina ponderosa or some other related species. Found in Louisville, KY, Drakes Formation (Bardstown Reef Site).

I know this is a long shot, but does anyone have any idea what this bivalve steinkern may be? It was found in the Upper Ordovician (drakes formation) of Kentucky. Brachiopods are overly abundant in many of the areas that I hunt, but bivalves seem to be scarce, or I am too used to seeing brachs to pick out the bivalves. Anyway, this is the one and only bivalve that I have found, besides a few possible fragments. I know it can be near impossible to identify any steinkern, but does the shape, size, or provenance give anyone an idea as to what this may be? It just looks so lonely on my shelf; I feel like if at least needs a name. EDIT: I should note that I have looked in the literature that I have (which is limited on bivalves) and can not find anything that I am confident in to use as an ID. My internet searching has not come up with a good ID either. If I can provide better pictures or different angles don’t hesitate to ask!

Monday morning was dreary here in Central Kentucky. The sky was cloudy grey, and the rain was sputtering off and on. I didn't let that dampen my spirits though. I had planned to go fossil hunting and nothing was going to ruin my day! I grabbed my hunting gear, a cup of coffee, dropped my daughter off at daycare, and headed out. I arrived at the Upper Ordovician (Drakes Formation) spot that I had found this year. The last time I visited this place I didn't have time to really enjoy myself. It was more of a smash and grab. A rush to see if anything was actually there and to grab what I could. This time I was determined to spend more time at my new found hunting grounds. Not even a little wind and rain would stop me. After about a 45 minute drive I arrived at the road cut. The last time I visited, I looked through the scree at the base of the cut and found items that, over time, had washed down from the rain. Many of these pieces didn't fair well with the 5-6 meter drop. After a few minutes of looking at the strata of the cut, I determined that the most fossiliferous layers were at the top 2 meters or so. I decided that I needed to check out the top instead of the bottom. I'm glad I did! After a short walk and hike up the gentlest slope I could find, I made it to the top. This is what I found. A loose layer of dirt (well mud since it was raining...) with coral heads and fragments everywhere! All different shapes and sizes. whole specimens just a few cm across to ones that where half a meter or more.

I made a trip to my new favorite Upper Ordovician (Drakes Formation) spot today (working on a field trip report ). I came across a few of these cylinders, which I believe are orthoconic nautiloids. I found them in many different sizes. Some taper as I would expect from an orthocone. However, they do not have the suture lines or septa that I am used to seeing. Some have what appears to be a possible siphuncle in the center while others do not. Here are a few pics of some of the more interesting ones. I can provide more if needed. Thoughts? Thanks in advance for any assistance! This one is about 3cm in diameter and 7.5 cm length. Number 8 in first pic. There are also a couple that have this twisting pattern on the outside. This one is about 5cm in diameter and 3.5 in length. Number 4 in first pic. Possible Siphuncle? 1 cm in diameter. Number 7.

Hello All, I was able to scrounge up a few hours of free time a couple of days ago. I decided to head towards the Bardstown Kentucky area to scout out a couple of spots I had on my list of possible collecting sites. The first 4 stops proved to be fossil barren. Feeling a little bummed I decided to get some lunch and regroup. After the quick bite to eat, I realized I was running out of time, but I figured I had enough for one more stop. I headed to a road cut that exposed Ordovician rock. More specifically the Drakes Formation. I'm not sure which Member of the Drakes Formation yet. Still working that out. It took a little longer than I anticipated to get to the road cut that exposed the formation, so I ended up with only 30-45 minutes of collecting time. After about 5 minutes of looking, I realized that my perseverance had paid off! I quickly collected what I could in the limited time that I had left to me. The site is definitely on my list now and I will be paying a visit again when I can stay longer. Below are some of my finds. Here are some in situ pics... A couple of nice brachiopods. I haven't had a chance to try and identify them yet, and I am not as good with brachs as I would like to be, so if anyone has a suggestion feel free to chime in. This little guy is hiding. Can you spot him? Sorry for the lack of scale ( I was in a hurry ) This colonial coral is about 6 inches across and not the largest that I found! (Favosites sp.) Possibly Foerstephyllum sp. Here are a few more pics after I got to the house... Here is the little guy that was hiding. Both valves were together. With a little clean up he should look nice. This one is nice, but very delicate as it has completely weathered out of the matrix. Another one of the nicer brachiopods that I picked up. It too had both valves. I picked up this hash plate. A lot of brachiopods, but there is also a layer of iron just below them. You can see it rusting a little in the top left of the photo. I'm fairly certain that this is a stromatoporoid. It is heavily crystalized and has a thin layer of matrix over the top, but I think with a little prep it will reveal its secrets. Last, but certainly not least, is a very large coral. Favosites sp. Foerestophyllum sp? It measures around 9 inches long x 7 inches wide x 5 inches thick.

I realize that this is very weathered and would be extremely difficult (and most likely impossible) to put any sort of specific ID on, but I was wondering if anyone thought it might be a gastropod? What is left of one anyway. I picked up the rock because it has a couple of brachiopods on the other side, and only noticed this after I got it home for a closer look. It’s Ordovician from the Drakes Formation near Bardstown Kentucky. Sorry for the lack of scale, but it’s about 1 inch (2.54cm) across.
