I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

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

Hello to all! Hope everyone is doing well, cause after my recent finds I am definitely doing well . So a little backstory: 10 years ago in grade school when I used to collect fossils with my father, we would never find any good fossils in shale. Always layer upon layer of the bland gray rocks with nothing even close to a fossil. For the longest time I never even bothered glancing at the large sections of shale dotting the many rivers of Toronto. jump ahead to the beginning of the month when I read some posts from @JUAN EMMANUEL showing some very nice nautiloids from shale. At first I didn't think anything of it and figured I'd never find anything THAT nice in shale. But, jump to a week later: While exploring a new location, I happen across a large section of layered shale on the riverbank and figured I'd try my luck - and started doing some digging. I pretty quickly came across a shell. A second shell. Then a third, fourth, fifth, and after chipping back the layer I found dozens of very tightly knit shells to my surprise. I was shocked to find anything after thinking for years that Toronto shale held almost nothing of interest. But still - they were ambonychia shells which I already have plenty of in my collection. So I keep looking around and chipping away at other layers, thinking maybe I'll find something a little more exciting. An hour goes by while digging in a somewhat awkward position, and my legs start to fall asleep so I readjusted my legs and out of the corner of my eye I noticed something right near my knee. My heart absolutely skipped a beat as I realized what I had found: A perfect and complete trilobite in the shale. After taking a closer look I realized there was in fact TWO of them right near each other! I hadn't found a trilobyte of this quality since grade school when I used to go with my father - let alone two. I just sat there for about 2 minutes staring at them, thinking they were going to shatter as soon as my pick got anywhere near them. Ultimately, luck played in my favour and the trilobites came out perfectly! But, the story doesn't end there, oh no! So now I'm going back to all these old places, primed with the fresh new knowledge of how to hunt shale. Although the work is pretty messy and uncomfortable, it seems to pay off quite nicely. And before I know it, a couple days later I end up finding yet another trilobite. But the crown jewel of the month came last weekend when I found two different nautiloids - one being an absolute MONSTER specimen, and the other being my most complete nautiloid ever (it even included the tip at the very end!). I just gotta give a big thanks to the people on this forum. Without the knowledge shared on this forum, I would likely have still been stuck in my ways avoiding any piece of shale in sight. I also have also included some other fossils that I found this month. [All fossils found in Humber, Etobicoke and Mimico river/creeks riverbanks - located in Toronto ON, Canada // Georgian Bay Formation // Ordovician (485.4 - 443.8Ma)] The first set of trilobites In Situ from humber river. The first two trilobites on the left and the later one on the right. The many pieces of nautiloid that came out during extraction. They unfortunately broke VERY easily so I figured there was no point stressing about it coming out in less than a dozen pieces. Here is what it looked like when all the pieces were assembled together (with the help of a little super glue of course). It even seems to have the very tip of the nautiloid as well (which would be a first for me)! here are a couple other decent pieces I found as well:

A very successful hunt (for me) in the Toronto area!!!
Monica posted a topic in Fossil Hunting Trips
Hi everyone!!! I had the afternoon to myself today because William and Viola are at day camps this week and my husband was busy, so I decided to check out Mimico Creek (Georgian Bay Formation, Upper Ordovician) by myself for a couple of hours. I didn't make many finds, but the finds I did make were super-amazing (by my standards, anyway ). As I was walking along the creek when I first arrived, I was checking out the wall of rock when I noticed a pattern: After gently prying out the rock, this is what I found: Hooray!!!!!!!!!! My first Flexicalymene granulosa!!!!!!!!!! For those of you who have read my trip reports and ID requests in the past, especially when I first started fossil-hunting in 2016, I always went out hoping to find a trilobite, and today I succeeded!!!!!!!!!! I then spent about an hour mucking about, not finding much, when I decided to hammer a big slab of rock that had some worn bivalves on the surface. Lo and behold, hidden underneath that layer of rock was the most beautiful Treptoceras crebriseptum orthoconic nautiloid that I had ever seen!!!!!!!!!! The bottom part of the fossil doesn't appear to have septal divisions, and it's a little flatter than the rest of the fossil - could it be the living chamber?!?!?! I cannot believe my luck today - this has been my best day of fossil-hunting in the Toronto area in the past 3 years!!!!!!!!!! I'm so excited!!!!!!!!!! I do have to play it cool at home, though - I don't want Viola to be disappointed that she missed out (I haven't yet told her what I did today - it'll be a secret for a while). @JUAN EMMANUEL @Wrangellian @Ludwigia @Malcolmt - I thought you might like to see- 63 replies

I was able to get some much needed "me time" yesterday. With all the worries of the world I have been in a foul mood lately, but I am happy to report that my mood has brightened significantly. . There is nothing like crawling around on a road cut, and hunting fossils, to really lift one's spirits! I spent a couple of hours at an upper Ordovician road cut that has been on my list to check out. It is an exposure of the Grant Lake Limestone. Shortly after I arrived, I realized that I was in for a real treat! This particular exposure is more fossil than limestone. Brachiopods are everywhere! Vinlandostrophia dominate the exposure; with Hebertella coming in a close second. Other brachs are also found, but less abundant. Orthoconic nautiloid fragments are frequently found and bryozoan encrusting is a common sight. I also found a few gastropods, and one trilobite piece that I am excited about. Unfortunately I did not take pictures in the field. It was a conscious decision. I just wanted to enjoy my time, relax, and focus on the hunt. I'll get some next time as I will definitely be going back. I did take a few pics of my better finds at home. Enjoy! First up are the Brachiopods. I found some nice whole Vinlandostrophia, and Hebertella, and what I think is Rafinesquina ( @Tidgy's Dad ) . I also took home a few single valves for study of the internal structure. I think with a little bit of clean up these will look great! I was happy to find some orthoconic nautiloids. They have been sorely lacking in my collection. I will have to research what species are found in this formation to come up with an ID. I have a few ideas, but need to confirm. Here are a few gastropods and bryozoans. I can't resist the alluring whirls of a gastropod. They seem to be uncommon in the areas that I hunt so I grab them whenever I see them. I believe these are new species of bryozoa that I will be adding to my collection. Which is exciting! Here is a tril-o-bit that I found. I'm very happy with it. Typical trilobite fragments from this area are not usually identifiable. Except to say they are possible trilobite pieces. This is a cephalic doublure of an Isotelus. Thanks to @piranha for help with the ID. All in all it was a great time. I got to relax a bit, forget my troubles, and brighten my mood. I also added some nice pieces to my collection. It was a good day!

Hello everyone! On Monday, I found a beautiful Treptoceras crebriseptum orthoconic nautiloid in a huge rock at Mimico Creek in the Etobicoke/Toronto area (Georgian Bay Formation, Upper Ordovician). It has been suggested that I might have a complete specimen, so I was hoping that someone out there might be able to let me know if this is the case or not. Here are some pictures... Whole specimen: Close-up of the base of the specimen (specimen has been turned over) - note that it is smoothly rounded and shows no septa - is this the fossilized living chamber of the animal? Close up of the tip of the specimen - note that it seems to end before the rock edge - is this the very tip of the animal? Close up of the piece that shattered off the tip of the specimen - note that it also seems to end before the rock edge: Thanks for your help!!! Monica

Here is an orthoconic nautiloid (cf. Treptoceras duseri) from the Cincinnatian of Ohio that I just completed. It is ~30cm (12 inches) in length. Unfortunately, I forgot to take "before" photos. I cut away about 75% of the plate it was in. About 50% of what you see of the fossil here was covered with matrix.

Is this what I think it is? A camera steinkern of an orthoconic nautiloid? This is from the middle-Devonian Silica Shale of Paulding, Ohio (although because it is quarry spoil, there is a possibility it could be the underlying Dundee Limestone). I don't think I've ever found an orthocone in the Silica Shale, let alone one this large. I hope this is not something that has been intentionally or unintentionally salted in from another site... That really burns me up.
