I was very happy to have my first ebay bid won and this plate was what I got. I've always wanted some fossils from the Lake Simcoe area but I never had the capacity to travel outside that far out of Toronto. Apparently there are two types of cystoids on this plate. This plate comes from the Upper Bobcaygeon formation, Ordovician period from Simcoe County, Ontario. It's a very different fauna from what can be found here in the bedrock of Toronto. Cystoids don't occur in the Georgian Bay formation. Paying for this plate took a bit of a hit on my wallet but I think I think it's worth it considering that I don't have anything like this in my collection.

Hi! We were at Craigleith, Ontario (Ordovician, lower Whitby formation) today for a toddler's fossil hunt birthday party, and found this neat assemblage of brachiopods, bivalves, and (I am guessing) trilobite bits. At least, they look trilobite to me, but I was hoping someone would be able to explain them. Are they curled up? Could they be part of the larval stage? Something else entirely? I didn't get a scale shot but by my memory I'd say the bits I am trying to figure out are <5mm across each. Thanks! Gavy

I am in the process of writing up a small piece for the university paper with a focus on some of the fossils that are part of the landscaping and architecture. Whereas the landscaping features are all identifiable as local Dundee Fm, I lack the knowledge to pinpoint the formation from which these rocks were quarried, and my investigation has yielded nothing to determine these details. The building was erected in 1993. The limestone used contains several corals (rugose and colonial), some substantially sized gastropods, and nautiloids. It is a light beige, very much mottled by the presence of numerous corals and Thalassinoides. I have my doubts that they would have trucked in the materials from out of province (it is a fairly large building). I am providing a few pictures here and can provide more if needed to ID this formation. The building itself has alternating bands of roughly hewn and saw-cut finished limestone. Some of the specimens in it can be quite large, and a few of the nautiloids present clearly show the siphuncle. I'm not sure if this will be enough to get a more precise ID on the formation, but I appreciate any help! EDIT: Selkirk Member of the Red River Formation, Orodovician. Quarried in Manitoba.

Hello everyone! I went out to my local haunt this past weekend, hoping to find a trilobite, and instead I found another specimen that I had not found up until this point - a coral! It was found at Etobicoke Creek, Georgian Bay Formation, Upper Ordovician. I'm thinking that it is a solitary rugose coral - confirmation of this, or a correction if I'm incorrect, would be greatly appreciated! Here are two pictures of the 5cm X 2.5cm specimen: By the way, would it be possible to identify the specimen down to genus or even species, or (a) is it too difficult to fully identify rugose corals without taking sections, or (b) is my particular specimen too squished to be able to identify it any further? Thanks for your help! Monica

There is nothing quite like a good hike wending around the river through the Carolinian forest ecosystem as the black-eyed susans and goldenrod stand proudly as the mayapples wither, and enormous puffballs appear while chipmunks and squirrels scamper about to hide their finds before winter comes. My goal was to return to an area that looked promising, mostly composed of rounded deposits from when the river was much higher some 7-10,000 years ago. The limestones in this area vary in terms of composition and state of preservation, as well as the deposition of marine critters: some stones will crumble into chips that are filled with large clusters of very tiny brachiopods, while others will have small crinoid columnals, long worm burrows, rugose corals, large-ribbed spirifers (some with very long "wings"), and even the occasional trilobite pygidium. Today's trip did involve getting a bit dirty and sifting through moss, frightening at least one salamander, a few garden snakes, springtails, woodlice, and an arachnophobe's nightmare's worth of large and interesting spiders. As a formation, Dundee is not particularly exciting, and one may feel a bit spoiled in collecting in other formations in the Devonian. Still, it is where I live, and the limestone seems to be the landscaping material of choice around here First up is a fairly well preserved tabulate coral, "front and back."

On Monday Sept. 12 I had some chances to explore zome of parts of the Humber river in Toronto, Ontario, because soon the weather will turn colder and the river waters wont allow exploration. I was walking at a certain part of the Humber river above Bloor St. when I noticed that I could actually see the river's bottom which is made of up shale bedrock. I decided to check the banks from the water. The pictures below were taken when I was in the middle centre of the river where the waters reached up only knee high. Below Bloor St. the water got mucky and there are several marshes lining up the banks of the river. I didn't see any exposures of the Georgian Bay formation at this part and instead I chose to walk north. In addition to discovering the shallowness, I also saw a potential exposure of the Georgian Bay formation, although the exposure could use more erosion to remove all the debris. The area where I discovered the exposure is in a park where all the banks got bulldozed several decades ago to control erosion, which covered most exposures at this park. The exposure revealed limestone layers interbedded with shale. Some of these layers got thicker than 15cm. One limestone layer was fossiliferous which I thought could make some nice hashplates. This limestone layer contained gastropods possibly Hormotoma (?). I have discovered a tiny gastropod hash plate once in Mimico Creek back in 2014 near the mouth. There were also plenty of pelycopods in the layer. I could not recall finding any cephalopods in the entire length of the exposure. A piece of gastropod hash plate I took home. The shells are preserved as internal molds. A Cyrtolites ornatus. I found 2 of these and this was the one I took home. A piece of ramose bryozoa.

PHOTOS ATTACHED I found this along the shore of Lake Ontario, in the small town of Port Hope, Ontario. The stone itself is about 1 1/2 inch wide but the stem-like print is about 3cm long. The circular print is about 0.5cm in diameter. Some sections even seem to have a bit of a shine to them when the rock is shifted from side to side in the light.

I'm still a beginner, and IDing finds is challenging. Anyone able to help me along? This fossil was found in Craigleith, Ontario. Ordovician shale. I didn't have a ruler with me for scale, but it was about 1.5" long and 1/3" wide at the widest point. My first thought was part of a trilobite but after a closer look at the photos it reminds me more of an Orthoceras. Only I have never seen one this small. Please point me in the right direction! Thanks! P.s. I've also attached a photo of our trilobite find. Pseudogygites latimarginatus?

Here is a highly inflated 3-dimensional Homocystites sp that was found this past Saturday May 14 on a very cold rainy day. The only bright note to the weather was that the wet matrix made it a bit easier to see the fossils. This is from the Ordovician Verulam formation and was found in a new blast pile from the previous 7 days. The homocystites typically found is Homocystits anatiformis which is found in the Cobourg formation. This species is typically a little smaller and is under review as potentially being a different species. Homocystites has an ovate theca and a fairly long stem (most missing in this specimen). It has a distinct pattern of radiating ridges on the plates that are very geometric in shape. It was prepped in about 5 minutes using low PSI (10) and dolomite in the 200 to 325 mesh range. No airscribing was needed. There is no restoration or repairs. The specimen is 36 mm long with a 27 mm theca (body) It is 11 mm wide and about 5 mm extends out of the matrix . I am considering finishing off the prep by completely exposing the specimen 360 degrees around, essentially making it a free standing on its stem specimen. I have seen a few prepped this way over the years and they are focal points in people display collections. What do you folks think should I take the chance and go for it.

Here is an extremely rare association of a pretty much complete Ceraurus globulobatus trilobite and a ventral partial amecystite echinoderm from the Verulam formation of the Brechin area in Ontario , Canada. Over the next month or so I will be taking a number of forum members and clubs to this area to hunt. Hopefully there will be some nice finds that we can share. This specimen was found by splitting rock at the end of April 2016. We tend to find the best specimens at this locality by splitting rock. the shaley limestone does not weather well once exposed to the elements.The preservation observed is quite typical of the ceraurus from this locality. The exoskeleton is extremely thin and flakey. The preparation was done mostly with very low pressure (8-10 PSI) 320 mesh dolomite . Prep time was about 5 hours over quite a number of days. Some dilute vinac was used to help consolidate the exoskeleton which was just screaming to want to flake off. This is the only time I have ever found an amecystite associated with a complete ceraurus. They are both rare finds in their own right.

On an annual basis we get one day to collect in a pretty amazing quarry in Bowmanville Ontario. This year 2015 was no exception. My buddy Dave here on the forum had a pretty amazing day. I suspect many of us would kill for even one of the specimens he found that day. I just realized that I have never posted how his fossils turned out. Turns out he is popping by this weekend to pick them up before a mineral and fossil show up in Peterborough Ontario. Fossil Forum member Northern Sharks is a very active member of the club (Kawartha) that is holding the event. Here are Dave's finds for the day as found. They are all isotelus A pretty damaged isotelus .... but a large one A nice Double Another nice double A nice single

Well once again, what is becoming an annual trip to St. Mary's cement in Bowmanville Ontario Canada was an absolute winner this weekend. This is a world class collecting locality that unfortunately is generally not available for regular collecting. A number of forum members were present but a big hats off thanks to our very own Northern Sharks (Kevin) for leading and organizing the trip this year. This is the only day in the year that the very active quarry with 5 levels is open for collecting. Approximately 30 collectors took advantage of this and made it a very special day. The weather was amazing for late October and not a drop of rain unlike some other years. The quarry was quite muddy as it had rained non stop the previous day but that is a good thing because all the rock piles were nice and clean. I only saw what a few collectors found as Quarryman Dave from the forum here and myself were too busy making then most out of our limited collecting time (9:00 to 4:00PM). We are all here for the trilobites...... I did see complete isotelus, ceraurus (2 species), thaleops and flexicalymenes that were found by people. My saw got a fair bit of use cutting mostly isotelus and a few ceraurus out for people on the 3rd level. I think Dave and I did reasonably well, though we only found isotelus and perhaps a thaleops that were keepers. We did find a lot of partial ceraurus but nothing worth bringing home. Dave found two double isotelus plates and we found a number of complete iso's.... Everything that we found was on level 3 and 4 of the quarry. We did not have time to look at levels 1 and 2 and level 5 seemed a bit too wet and muddy for my liking. From what I heard from a few others nothing of note was found on level 1 or 2 this year. I know Peter Lee spent some of the day up there and he did not find anything but partials from what I recall. Here is the group picture of what we found all unprepped at this point (the trip was only yesterday) We should get a few nice ones out of this batch once I get them prepped. I will try to post some pictures as they get completed but that will not likely be for a while as I have a large backlog of material to prep for myself and others. Other members of the forum that were there please jump in and show us some of what you found. ..........

Sometimes you get a very pleasant surprise when you get your finds home and start prepping. I was very fortunate to find two relatively complete Amecystis laevis this Saturday October 31, 2015 up at the JD Quarry near Lake Simcoe, Ontario , Canada. They most likely came out of the very top part of the BobCaygeon formation as they were both found in a recently created pile and not in situ. If not it was from the very bottom of the Verulam This picture because of the lighting used came out a bit blue. I am not the best photographer around. The specimen is on an 85mm * 66mm matrix and is 79 mm long from tip of arm to tip of tail (about 3.1 inches) . The theca on the amecystis is 17mm wide by 22 mm long. The Amecystis is a dorsal orientation. The edrio is approximately 6 mm in diameter. I believe this to be a Amecytis laevis (Raymond) by the way Thanks for the correction Kevin (Northern Sharks) there are definitely no pore rhombohedrons on this specimen. It is a shame that the Amecystis and the edrio both have some slight damage to them from the quarry blasting. But they are still very good specimens. The amecystis is fairly well inflated and nicely colored. Here is a better picture showing the true coloring. But to my surprise it has a very nice attached travelling companion in a edrioasteroid which I believe to be an Isorophusella incondita. What makes this super interesting and probably quite rare is the fact that the edrio is attached to the amecystis and may well have been there when the amecystis was alive. I wonder if anyone else has ever come across this particular association. Edrios are often found attached to brachiopods in this locality. This was prepped using 40 micron dolomite under a zoom scope at 22 PSI using a Comco .018 high precision nozzle on a Comco air abrasion unit.

This week I got my monthly TTC Monthly Metropass for the first time ever and so with this card in my wallet I was excited that I had unlimited freedom to use the transit to go wherever I want in the city of Toronto for the whole September. Yesterday, while travelling with my card in wallet in Scarborough after finishing an assessment, I came across a creek right at Progress Drive and went down to explore it, in hopes of coming across the Whitby formation. I had seen bits of information regarding outcrops of the Whitby in Scarborough on the net, and I took this opportunity to explore as I live far away from Scarborough. I went down on a driveway I found behind a building and descended below to the bottom. From the edge of the creek I saw no exposures of the Whitby formation but instead saw outcrops of sand, a bit similar to what I saw at the Don Valley Brickworks. Some of the outcrops' bottom were ridden with overgrowth, so I chose the one that had the least, which was this one. The highest point of this outcrop would be around three storeys high and streches for several metres. There's also a substantial sediment material that has fallen off at the bottom and the vegetation on the bottom isn't as thick.

Hello, I am Speo, I am 45, I am located in Ontario, but born and raised in Eastern Europe. As a kid I used to collect some fossil snails from a river nearby my city and I still have few of them today. I was not really into fossil hunting, but they always fascinated me and two days ago, while stepping on a boulder from a wave breaker, something caught my attention. Please tell me that I am not crazy and this is indeed a fossil. Could it be a trilobite?

Hello everyone, For my parents 36th wedding anniversary I thought I would surprise them with a fossil hunting vacation as they are both avid fossil enthusiast. I would really like to plan a trip for them somewhere in Alberta or in Ontario but I’m not sure where to send them or how they should go about finding cool fossils. They are not the most competent outdoorsmen so day trips would probably be ideal. Any advice would be greatly appreciated

Hello fellow fossil hounds! Just picked these up in a truly wonderful shop in Lacombe, Alberta, Canada. I think they're from the Ordovician of Craigleith, Ontario, Canada. Pseudogygites latimarginatus? Same Id for both? The labelling was a bit unclear... 1. 2. Have a great day, and thanks in advance for any and all responses!

From the album: Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)
Little ripple marks caused by the gentle currents on the shallow late Ordovician sea floor of Toronto. Georgian Bay formation, Humber member(?), Humber River area, Toronto, Ontario. Limestone slab, the coin is a quarter at the bottom for scale. Hmm, I'm beginning to decide if I should have taken this home with me today. Also at the bottom are two clam negative casts: a Whiteavesia and a Modiolopsis.© (©)

Ever since summer vacation started I have been free to explore the Humber River area and made frequent hunts there in the late Ordovician rocks of the Georgian Bay formation of the city of Toronto. I realized that I did not have a substantial amount of material from this location that I discovered by accident, and so I decided and started to invest some time in exploring this particular location. Last year I only made seven visits, but I did not hunt productively, as I was in my first year of fossil collecting and as a result I had very little material from this location. I knew this location that I accidentally stumbled on had a lot of potential, considering that a great deal of the original exposures are still intact and there were few disturbances done by tractors, whereas compared to Mimico Creek a great deal of the original and actual exposures have been buried. I made three different visits, the first trip I believe was last week and the third today. On the first trip I only took home three specimens, but gradually as I hit the third visit the amount of my finds increased. On the first trip I only found at least three materials. The first thing that I discovered was a Treptoceras crebiseptum specimen. What made me surprised with this specimen was that this specimen actually had Cornulites sp. attached to it. I've never seen something like this in Mimico Creek. There were tubes of the worm attached on the orthocone and also the orthocone was not squashed flat because of the nature of the shale it is in. Actually, I noticed that certain shales in this location did not squash completely flat the orthocones that get preserved in them, which is very different from Mimico because most of the orthocones I find in Mimico shale are compressed. Sorry if I didn't carry any macro lenses and a good camera to capture the Cornulites, the location's flood from a recent rainfall made the place really mucky and wet and the flood waters were just starting to recede. Out of all the Treptocerases that I discovered on that trip, this was the only one that I decided to take home.
