Hi everyone! I'm finally starting to go through some of the things that Viola and I found when we visited Hungry Hollow back in April in preparation of doing a trade, and I was looking for some help with identifying the following items: Item #1, front and back: A tabulate coral perhaps? I think I can see corallites in the "back" photo... (or maybe a bryozoan...) Item #2, front and back: Another tabulate coral? (or perhaps another bryozoan...) Item #3, front and back: A bryozoan? This one looks different - it kind of looks like frilly layers... Thanks in advance! I may end up posting more stuff so keep an eye out for more requests for help!!! Monica

The missus had an errand to run and asked if I'd like to be dropped off at Arkona for a few hours. Of course, I never turn down an opportunity to get out and collect! It started drizzling, and then pouring. I was still adamant on going, and glad I did. Planning around the weather this year in SW Ontario seems an exercise in futility, as it has been a largely wet and unpredictable season as opposed to more even keel prior years. One of the slim advantages of going to Arkona in the rain is that you can actually see things much better when the ground is wet. As I was going in to the south pit, some intrepid fossil collectors were on their way out, soaked to the skin. They had had enough. They probably thought me foolish for thinking of going down there. And it was indeed mucky. At one point, with the accumulated sticky Arkona clay under my boots, I briefly experienced what life would be like four inches taller. The rains varied in intensity, from a mild drizzle to a somewhat frustrating downpour. Undaunted, I was going to make the most of my two precious hours even as I felt a whole lot heavier being soaked through, runnels and rivulets of rain running roughshod over my ragged mien - lol. I was not gunning for my usual fare this day given the short amount of time and the weather conditions, so it was more about casual surface collecting in the south pit. And so poking through the Arkona clay, I figured I'd beef up my goniatite collection. Here is a row of them in ascending order of size. I am actually quite surprised and proud to have found a fairly large one in this formation, as those generally are nested in the matrix of the Widder Fm above:

Whitby Formation now Blue Mountain Formation??
JUAN EMMANUEL posted a topic in General Fossil Discussion
I feel like I'm behind this but is it true that what was called the Whitby formation in southwestern Ontario is now called the Blue Mountain formation? Does anyone know the real story behind what happened officially? -
Hey!! Are these cephalopods? More specifically Dawsonoceras? Found in Vaughn Ontario near a stormwater pond - I have a feeling it's from a local quary since this pond is a man made structure. TIA!!

Brechin, Ontario with Malcolm and the New York Paleontological Society
Jeffrey P posted a topic in Fossil Hunting Trips
The weekend of June 24th and 25th I participated in an outing with the New York Paleontological Society led by my friend, Ray McKinney to Brechin, Ontario. TFF Member Malcolm led our group into the James Dick quarry where both Bobycaygeon and Verulam Formations are exposed. These are Middle Ordovician from the Trenton Group and contain a wide variety of invertebrate fossil fauna. Also met other TFF members Kevin (Northern Sharks) and Joe (crinus). Most of the quarry is the Bobycaygeon and the very top is the Verulam- only accessible near the entrance, but I got some excellent well preserved matrix plates from there. I spent the second day combing the spoil piles. This first picture is Lake Simco by Beaverton where we stayed. Malcolm in the middle, explaining the quarry geology to NY Paleontological Society members.

From the album: Credit River Fossils from Streetsville, Ontario (Georgian Bay Formation, Upper Member)
Homotrypa sp. (streetsvillensis?, Dyer, 1925) Georgian Bay formation, late Ordovician. Plate of unidentifiable bryozoa. Found as a loose specimen on an exposure on the Credit River at Streetsville, Mississauga, Ontario. Approximately 12 cm long and 10 cm wide. Comes from the Homotrypa streetsvillensis zone layer of fossiliferous limestone full of bryozoans. The layer is around 18 inches to 2 ft thick, as described by W.S. Dyer in his "Stratigraphy and Paleontology of the Credit River" on pg. 50.-

Found at a quarry in Eastern Ontario. We chiseled it from the rock at the quarry. Not sure what it is, we think it looks like teeth but we have no idea what from. Any help would be great

Just got back from Brechin and had a lovely time collecting with TFF members Malcomt and Ludwigia. Managed a pretty decent haul for my first time up there, and definitely my thanks to Malcolm who is a real veteran of the place in pointing out where to look and how to work the rock. It was a bit of a drive for us, but it was lovely. We had to leave a bit earlier to beat the traffic. So, pictures equal thousands of words, and all that. A few of our other members will probably have some other stuff to add to this thread. First up are hash plates. I am personally fond of them, and since these are in an Ordovician formation (Verulam) I've never collected before, it is all a great novelty to me. Gastros, brachs, byrozoans, trilo-bits, etc: And, a healthy serving of gastropods. I particularly like the large, high-spired ones (Fusispira sp.?) that weathered right out of the rock for easy surface collecting.

Beyond being able to pick out a fenestellate bryozoan, my knowledge of bryozoans is quite poor. I was hoping for an ID on this one (bryozoan? sponge?), which is among the most peculiar I've found around these parts (these parts being fill deposited from Bois Blanc / Amherstburg Fms). Those large, circular pores were what persuaded me to take it home. Is it even a bryozoan? It is about an inch (though no saying how large it might have spread).

When I found this fossil it has some green algal growth on it as I found it on the grass. The algae did not cover the entire fossil but is there some way I can remove the yellow coating of this fossil? I've been scrubbing it with a brush under running water for a while now and some of the dirt does come off.

Lately if you have seen some of the topics I've started, these trips revolve around an Ordovician reef I came across by the Credit River in Mississauga, Ontario. One of the few things I discovered while exploring these spots is that there are plenty of Stromatocerium sponges which I red is a stromatoporoid. My question is, can anyone lead me to any papers about the growth forms of Ordovician stromatoporoids? I have found specimens of stromatoporoids and from the way I see it, some of the specimens I found of the same species have different growth forms. Some have those things they call monticules on the surface, and some don't exhibit them at all. Instead these specimens exhibit cracks and splits on the surface of the organism with irregular bumps and overgrowths. I'd like to know what causes this. Some of these sponges, from what I have collected, colonize some pieces of Prismostylus on the top.

Finally Reached That Exposure- Credit River by Streetsville
JUAN EMMANUEL posted a topic in Fossil Hunting Trips
Yesterday, after countless trips and exploring at the same old spots on the Credit River in Mississauga, Ont., I finally mustered the courage to go and wade on the water to an isolated exposure out the Georgian Bay Formation at Streetsville, Mississauga. I wanted to collect fossils that were not worn out as these were all I was finding in my old spots. I have been setting my eyes on this exposure from the other side of the Credit River for some time now ever since I started collecting along the Streetsville area and it could possibly harbour fresh material. The temperature of the afternoon was around 16-20 degrees Celsius so the water was not chilly as I was expecting it to be. I crossed the water barefoot with the water reaching up my knees at this tributary that separated the exposure from the main path. The Credit has many tributaries flowing and where the these tributaries converged the river, many exposures can be found along these places. After crossing I reached the other side without slipping on the slimy bottom. The exposure had thin footing for exploration but I was able to walk back and forth without slipping onto the water..thumb.JPG.92eb43aab8e77866c42e31c8c3ed9a80.JPG)

Amecystis laevis (Ulrich and Kirk, 1921). Upper Bobcaygeon Formation, Middle Ordovician. Simcoe County, Ontario, Canada. This specimen is among the ten specimens on a hash plate that was won in a bid and bought over online auction site. The specimen is missing the two tentacles at the top of the head. Length of the specimen was measured by using a measuring tape.

Lingulichnus verticalis (Hakes, 1976). The elliptical shaped and concave burrows or holes were made by a linguloid brachiopod burrowing in the sediment. I took this plate home as I have never seen so many Lingulichnus burrows on one plate. Rock is limestone and was most likely mud before it lithified.

Hi everyone! Well, Viola and I have officially expanded our fossil-hunting area to include Hungry Hollow!!! We joined in on a field trip organized by the Niagara Peninsula Geological Society this past Saturday, April 29th, and we spent 3 fairly cold and windy hours scouring the South Pit for fossils. Luckily, the pit's rocks are incredibly fossiliferous, so we came away with many specimens. Here are a few pictures of our adventure... Picture #1: Viola in the centre of the pit, looking for little things like brachiopods and bactrites: Picture #2: Viola at the side of the pit holding up her favourite solitary rugose coral: Picture #3: Most of our haul for the day: Picture #4: Some nice hash plates from the pit, mostly containing brachiopods and Tentaculites sp.: Picture #5: SO many rugose corals in the pit!!! Picture #6: A bunch of things, including brachiopods (Mucrospirifer arkonensis and others), crinoid bits, bryozoans, corals, smaller hash plates, and my favourites: pyritized bactrites: Picture #7: A pretty star-shaped encrusting bryozoan (Botryllopora socialis) on the side of a rugose coral: Picture #8: Some organisms on a Mucrospirifer arkonensis - perhaps a couple of gastropods or ammonoids, a bit of encrusting bryozoan, as well as a couple of tiny ostracods (maybe): Picture #9: An Eldredgeops rana cephalon (partial): Picture #10: A trilobite pygidium - it's orange and oh-so-cute!!! I have to thank @Bob for showing Viola and I around the pit, and telling us about the fossils that we were finding - he was an amazing help!!! We had such a great time - hopefully we'll be able to visit again soon!!! Monica (and Viola)

Found this large broken tooth turned up in a agricultural field, 1/4 mile from a large river. the tooth is 2.5" long & i would say that the broken root end was probably an inch longer. Any help would be appreciated. Found in SW Ontario, Canada.

Well I went out collecting on Saturday which turned out to be a cold and windy day. Got there after a two hour drive at about 7:45. Was too cold overall with the windchill, ended up leaving about 2:30, usually stay till about 4:00. I was pretty disapponted on the day as I only brought 5 pieces of matrix home with me. My two regular collecting buddes had no better luck (perhaps even less) than I did. One of them even gave up at 11:00 which was very unusual. For me, a crappy disarcticulated isotelus about 2 inches long but it had a nice cephalon with perfect eyes. A starfish which now that I look at it under a bright light and scope is probably a species I have never found before and two cute little hash plates with a bunch of cephalons from Flexi and calyptalaux on them. What actually made my day now that I have finished prepping it is a split that I did that showed the outline of a trilobite. In the field under cloudy conditions I thought it was perhaps a flexicalymene (nothing to get excited about) although it was fairly large and prone. Here is what it looked like before any prep. You can see why I was not too excited, it is not much to look at. I should have recognized in the field that this was a ceraurus with some potential but being a dull cloudy day it went into the bucket with little thought as to it being anything good. Well at 10 minutes into the prep using dolomite <325 mesh abrasive in a Comco air abrasion unit at 30 PSI with a .018 nozzle it was obvious that it was a ceraurus and if the pygidium was there under all the matrix then probably a fairly nice one. Usually the ceraurus found at this location are not buried in the matrix and are very flaky. Here is the bug at 10 minutes of prep. Definitely starting to show some potential

I'm new to this forum but thought you might be able to help. I found this fossil near to the whirlpool rapids in the Niagara River gorge in southern Ontario, Canada. As far I can figure out this looks like a leaf, perhaps some sort of angiosperm. It is a few centimetres long. However, the geology of the area is almost completely Silurian rocks. This wasn't found in situ so could be from rocks in the cliffs above, younger rocks no longer found in the area or introduced by people (unlikely). So two questions really. 1. Type of fossil? 2. Geological time period/range of fossil? Thanks!

Hi Everyone, I live in Toronto Ontario. I've had a lifelong interest in science, particularly biology. I studied marine biology at Dalhousie University in Halifax and spent a lot of time studying many of the invertebrates (extant and extinct) that I've seen represented in the fossils pictured on this forum. I don't have any real fossil hunting experience and never really thought too much about fossils until I started looking closely at the rocks on a beach near Tobermory Ontario with my daughter. After learning that the area was a tropical shallow sea during the Silurian period, and that the fossils we were finding were of a long vanished coral reef I started to get hooked. I'm interested in learning about fossil hunting from the knowledgeable members of the forum, and of course, viewing the photos that members post.

The day began with a morning hunt at my honey hole at "riprap hill," and I was pretty much skunked. I think, after four years, I've picked the place over. There is virtually nothing left for me to split, and given a mild winter, nothing new has weathered out. But I at least was graced by the sight of the living in the form of this majestic animal: image.jpg_1

Well every now and then you get lucky and don't even realize it. Was out collecting on Sunday and found what I thought was a few exposed spines of a meadowtownella trilobote. To my surprise when I got home and prepped it , turned out to be something totally different.. Trilo was prepped using 200 mesh dolomite at 20 PSI with a .015 nozzel. Prep time about 15 minutes, very fragile but no consolidant , glue or restoration. Drumroll... as I have never found this species before at this location or anywhere else..... This was found on the surface of a good thousand pound slab in a recent blast pile from the upper part of the verulam exposure at this quarry. Thankfully I had lugged my diamond saw down to the bottom of the pit otherwise this fella would have ended up in the crusher. My buddy Northern Sharks was at the quarry hunting the upper level and never made it down to the bottom (a long trek). I had commented to him over email that I had had a so-so day getting 5 or 6 trilos but nothing spectacular. Now that this is prepped I have changed my mind... I now rate it as a pretty good day. (also found a couple of isotelus, a couple of ceraurus, a very nice syringocrinus and a flexi) I believe it to be an inverted and essentially complete Hypodicranotus striatulus (Walcott) (perhaps pirahna will jump in here with his expertise Notice the partial hypostome whose shape is quite indicative of this species. In fact I may actually have another hypostone in a hash plate matrix that I found a few years ago in the same general that I thought came from a septapsis Trilo is 21mm long by 15.3mm wide

Hi guys I just wanted to share some of the more interesting and unusual cephalopods that I've managed to amass over the past and nearly 4 years of hunting along the creeks and rivers of Toronto, Ontario. I was cataloguing them on my computer and I figured out that I might as well share them. The ones below all came from Mimico Creek. All the fossils belong to the Georgian Bay Formation, and are Late Ordovician in age. A Treptoceras crebispetum (author unknown) covered in an unidentified bryozoan. Length is around 15 cm. My first complete specimen and the same species as above. Complete ones like these found in the shale are often squashed. The body chamber is intact and the specimen approaches nearly 40 cm in length. The smallest complete specimen of the species that I have. This has the body chamber. Length is approximately 10 cm.
