Today I decided to go and visit a roadcut that I red on one of the Silurian literatures I got my hands on (a big thank you to those that led me to those PDFs relating to the geology of the Niagara Escarpment). It turns out the roadcut on the Niagara Escarpment is near my home which is a pleasant suprise to me, considering that I have been disappointed by the Queenston formation. This roadcut is actually several exposures that run on an access road that can lead one to the upper part of Hamilton, Ontario. Here is the exposure I decided to explore. I chose this exposure as the access is a busy boulevard with cars driving by with no sidewalks and pedestrians. I had several people honk and call out to me as I was exploring the site. Maybe I should have worn a safety vest of some sort? Is that even necessary?

Exploring the Queenston Formation along the Red Hill Creek
JUAN EMMANUEL posted a topic in Fossil Hunting Trips
Today I managed to explore and observe an exposure of the Queenston formation up close here in Hamilton, Ontario. I chose a site along the Red Hill Valley Expressway that was easy to access and get down to for a close look. The creek is right next to the highway. I have always passed by this exposure and anticipated the day I'll be able to observe it. The Queenston formation is the last Ordovician formation in south-western Ontario before the rocks hit the Silurian age. The Queenston is what overlains the Georgian Bay formation, the formation I use to hunt in frequently in Toronto, Ontario. This is Red Hill Creek as it passes by next to the Highway. -
Honestly I seriously thought about not posting this find from yesterday. I did not want any of you thinking that the fossil gods where being grossly unfair. But then I decided that in all likelihood most of my comrades here on the forum will never have seen one of these, never mind one this is pretty much as good as you find them. Promise not to submit it for IPFOTM. Four of us were out collecting splitting a lot of rock and excavating near the area that I found those two amazing Astrocystites a few weeks ago (August Invertebrate Fossil of the month) After a very unproductive 5 hours two of my friends gave up and headed home leaving the two regular diehards (Myself and J.) Seeing as no one had found anything of note splitting rock in the blast piles, we both decided decided to work on excavating the wall about 25 feet from the area that produced the astrocystites and a wealth of other cystoids and edrioasteroids. After about 8 hours of wall excavating J. was rewarded with a gorgeous complete extra large pleurosystites. As for myself I somehow once again lucked out finding this spectacular Amygdalocysties florealis. Only a few of these are found each year at this site and rarely are they as complete as this. This is a class of echinoderms known as paracrinoids. There are only two species represented in southern Ontario the Comarocystities and this one the amygdalocystites. These only occured in the Ordovician. I guess they were a failed experiment. This specimen was found at the top of the BobCaygeon formation. Here is what they look like...... very weird........ but cool Believe it or not I spent about 5 hours prepping this with 40 micron dolomite, .015 nozzle and 18 PSI. Here is the before picture. I actually knew what it was in the field because of the distinctinve pattern of the plates. I aslo could see that it had a stem and at least one arm in the field. I had to field douse it thoroughly in Cyano as it looked like it was ready to flake off the plate at the slightest tough. Here it is as found.... (not much to look at) Here it is prepped The finished creature is 35 mm x 20 mm wide The whole plate which also has a small crinoid on it.

Hello everyone! Yesterday, Viola and I were able to visit Hungry Hollow (near Arkona, Ontario), and we had a wonderful time! When we last visited the site back in April, it was cold and cloudy; yesterday, it was hot and sunny, and there were no bugs to bother us, so we were in the South Pit collecting fossils the entire time (about 3.5 hours). Unfortunately I didn't take many pictures, but I blame that on all of the fossils that were calling to me - they wouldn't let me take a break to take pictures! In all seriousness, though, it was a fantastic day out with my little girl - please enjoy the pictures I do have to share with you. Oh, and for those of you that aren't familiar with the rocks at Hungry Hollow - they are Mid-Devonian. Picture #1: Viola just before we headed into the South Pit Picture #2: Viola searching for brachiopods (as usual!) Picture #3: a spiny brachiopod - does anyone know its identity? @Kane Picture #4: a couple of "mommy and baby" Mucrospirifer thedfordensis (I think!) brachiopods - Bob O'Donnell found and gave the one on the right to Viola, while I found and am going to keep the one on the left so we each have one to remember our times together fossil-hunting Picture #5: a gastropod - Platyceras sp. - does anyone know the species name? Picture #6: I found my own Tornoceras sp. - hooray!!! Back in April, Bob found one and gave it to Viola, and I have to admit that I was a little envious because they're so pretty. Well, yesterday I found this specimen, and it's a really pretty shade of purple - I'm in love (Is the species name arkonense, by the way?) Picture #7: A coral with an epibiont on top of it - someone yesterday (I believe his name was Darren - he also gave Viola a bottle of water while we were in the pit - a very nice guy!) told me what it is, but I can't recall what he said. Any ideas? Picture #8: This is probably my favourite hash plate that I found yesterday because there is so much going on - bryozoans, corals, and crinoids - oh my! And perhaps a bit of a trilobite peeking out near the top...? Well that's all for now. I'll likely add more photos after we wash Viola's finds and look through all of our fossils more carefully. Thanks for reading! Monica

Hi, I found this fossil a few years ago on the shoreline of lake ontario right in the city of Kingston Ontario. I believe the exposures here are upper Ordovician age limestone (Gull River formation) however there may have been fill brought in from elsewhere to stabilize the shoreline so this fossil may not be exactly local. It looks to have a siphuncle (acentral) and sutures (relatively close together) so I thought it appeared to be some type of orthocone nautiloid of some type. Based on Bill Hessin's field guide "South Central Ontario Fossils" I thought i might be Gonioceras anceps or Actinoceras but I really don't know. The pics here are not great, but hopefully someone has some ideas. Thanks

The older I get, the more spring has an appreciable effect on my energy and outlook. But, it also signals an end to cabin fever and getting back into the hunt. Spread out over two non-consecutive days, I took to getting back into practice by doing some collecting nearby. There are no "wow" specimens here, but certainly typical ones I find from a wide mix of stratigraphic units all in one place. The first is one of the areas I focus on, which are mostly little gullies where some larger rocks are exposed, and smaller ones get sifted.

It is the last hurrah for me before the school year begins and I'm back riding the lectern. As some of you already know, I am due at a very special quarry near Lake Simcoe to collect with our intrepid @Malcolmt after his jaw-dropping Astrocystites finds. This space will record some of my journey there, and of course our time in the quarry. We made our way out from London going north by northeast this morning and took the back roads. Those of you who have traveled the Grey Highlands and Blue Mountains area know how breathtaking the scenery can be. We found ourselves in Craigleith by about 2 pm. As some will know, the Craigleith and surrounding areas along the lake are full of Whitby Fm shale from the Ordovician, similar to that which one may find in Ottawa's Billings group. They are full of Pseudogygites latimarginatus moults. Of course, it is not legal to collect at the provincial park. The first is a display piece of a full Pseudogygites.

I had an amazing day up at my local spot collecting. There had been no new blasts or work at the quarry so I decided to scour the pit wall near the north end of a pond area near the road way down into the BobCaygeon formation material. Those who collect there will know the general area. . To my surprise I found very quickly a fortediscus edrioasteroid about 1 1/2 inches across. Will likely post something on it once it is prepped . I quickly noted that there was a crinoid layer about 3 inches above the layer the edrio was on and that there was a layer about 3 inches below the edrio that I could make out tail sections from pleurocystites. Well five hours later we had taken out probably a ton of rock between two of us.We had to remove about 4 feet of overburden to get to the first layer. If only we had brought a 6 foot pry bar we would have been golden. Regardless we excavated about 10 feet of wall going back about 2 1/2 feet. My reward an edrioasteroid, a cyclosystoid, a plate with two unknown at this point large crinoid calyxes, 13 cycstites (a combination of pleurocystites and amycystites). My friends reward an edrioasteroid and some crinoids.... We will be back next weekend with some heavier bars and my friend the excavating machine Kane...... Here is some pictures of the first one I prepped this morning.... We are blessed with some great collecting up here in Ontario Canada...... A number of you have been up to hunt with me over the years..... Hopefully more will make it in the future......
