hi i am wondering are there any fossil shows in Ontario that have lots of dinosaur fossils thanks
-
Favosites sp. from the Devonian Hungry Hollow member in Arkona, Canada. One of the more interesting corals I've collected, I'm trying to narrow down the species if possible. Any ideas?
-
I found this orthocone a while back at Arkona (devonian) and I thought it was dolorthoceras, but now I am not so sure. It has a strange mark protruding from centre of each chamber. Any help would be appreciated! d!

Hello there! This past Saturday, I went on a "field trip" to Hungry Hollow near Arkona, Ontario (mid-Devonian in age), and I found one weird item. It's an echinoderm of some sort, but which sort? A crinoid holdfast? Something else? Please see the photos below and let me know what you think. (By the way - I didn't make it home from work in time to take photos in natural light today, so I apologize for the fairly poor photo quality - if it's sunny tomorrow I can get better pictures then. And I also apologize for my blue finger in the photos - my students and I were looking at cheek cells under the compound light microscope today and some methylene blue got on my fingers - oops!) One end showing the pentaradial symmetry: The other end not showing much: Side photos: Thanks for your help! Monica

Today Deb and I made the two hour drive up to just outside the town of Formosa, Ontario, to have a look at the Formosa reef limestone, which is part of the Amherstburg Formation. This road cut is the type locality for this material, and it was humbling to be at the exact same location that researchers of yesteryear such as Ludvigsen and Fagerstrom derived their material that formed the basis of their published work on it. Here are some shots of the road cut. Hardly does it justice. This represents a single, massive biohermal knoll. I've wanted to visit this site for a while now, having read two key papers on it. Most of the non-coral fossils are found on the south edge of the cut, as it is assumed that this was the windward side of the knoll that captured much of the debris swept in by the currents.

Hi all, It's been a while since I posted a trip report but I was feeling like posting last evening as well as testing out my new photography rig. I moved houses two years ago and lost my lovely brick wall backdrop (the exterior of back of the house) which allowed photography in natural light. The new house is all vinyl siding outside and I have more shade so less opportunity for good sunlit pictures. However, one corner inside the house has a bricked area where a wood burning stove used to be so I have decided to set up some lights there. The pics came out ok so let's proceed with the report. I recently went up to the St. Mary's quarry in Bowmanville, Ontario on a scheduled trip with the local Scarborough club and also stopped off at Arkona while in Canada. I did pretty well at Arkona where I found four Eldredgeops trilobites and two Blastoids among other finds. Nucelocrinus elegans from the Hungry Hollow member of the Widder formation. Sorry, no pics of the Trilobites due to some back spasms but I got these pics of a nice Atactotoechus fruiticosus branch also from the Hungry Hollow Member of the Widder formation. Then I went to the St. Mary's quarry on Sunday where I took a tumble down the rock pile and hurt my ribs. Lucky for me my hard hat took the brunt of the impact my head made with the rocks. With nothing broken and still able to move around, I stayed closer to the ground and found this partial, eroded Isoltelus sp. that is inverted and still shows the Hypostome in place. I also found a plate with Graptolites but that was too heavy to hold and photograph last night. I'll post it tomorrow maybe. Finally, I drove home on Monday and stopped off at a place in New York where some of the Kashong Shale member of the Moscow formation is exposed and found these two surprises. A cephalon of a Dipleura dekayi with some of the shell material eroded away. I think the eye is intact and waiting to see again once some rock is removed. And here is a closeup of the shell on top where you can see the stippled pattern where sensory pits used to be. Lastly I found a pygidium that I am not sure of the genera on. Possibly a Basidechenella sp.? So not a bad trip at all, despite the injury. Good news is that I am healing nicely but still have some soreness and muscle spasms. I'm looking forward to my next trip up in the spring and hopefully will avoid the health scares.

Found this one in Bowmanville (Mid Ordovician, Cobourg? Formation) last weekend. My best guess is Thaleops laurentiana cephalon but id like to have a better idea what it is before I attempt any more prep. Have not tried yet but probing with air abrasion looks like it will be difficult since the matrix is full of calcite or some other crystals. @Malcolmt @Kane @Northern Sharks

My 5 year old found this near a river edge in Southern Ontario. Any ideas?

Hi yesterday I went to the Ancaster gem and fossil show I got a couple things just wondering what do you think of them? First to last theropod bone fragment from cedar mountain formation Utah the they said it was found with identifyable bones that are theropod next dinosaur coperlite from Madagascar mahajanga formation last triceratops tooth hell creak Montana.

We took our girls fossil hunting near our house for the first time. We found rocks with lots of little brachiopods but I also found this. Is this a cross-section of a cephalopod maybe?
-
I recently found this trilobite tail with a piece missing out of it on both positive and negative sides. Could it be a bite mark?

Unknown item (sponge?) from the Credit River in Mississauga, Ontario
Monica posted a topic in Fossil ID
Hello there! Last month, I visited the Credit River in Mississauga, Ontario, Canada (Georgian Bay Formation, Upper Ordovician) to look for some fossilized corals. In addition to a bunch of weathered colonial rugose corals, I found an item that I think is something, but I'm not sure what - perhaps a sponge? Here are some photos of it: Side view - dry: Top view - dry: Top view - wet: Thanks so much! Monica

Another trip to Etobicoke Creek, this time near Sherway Drive. There were lots of nice things, but quite the same as usual, so I concentrated on looking through the gravel for smaller pieces and ended up with a box of knick-knacks to explore. As usual, my wife found all the interesting items. At one point I picked up a rock and got surprised by a little snake. He was really steamed. We had a delightfully relaxing outing.

This was found in Cayuga Ontario (Devonian) in 1988 and is still marked in my collection as an unknown. I have had a number of suggestions over the years as to what it is but nothing that screams that's it for sure. I always thought that it was echinoderm of some type but others have suggested eurypterid. Any thoughts. It was found at surface level of an abandoned water filled quarry so there is no assurance that it actually originated at that quarry but it probably did as it looked like the same matrix as the surrounding rock. Please jump in with your thoughts... I would really like to figure out what it is as I have nothing else that remotely looks like this

I was determined to trace a shale layer into a hillside, and managed it: what a joy to discover more shell imprints. The genus I'm looking for is Rafinesquina, or something similar. Also got some colonies of things and trace fossils out of the muddy creek area. This place is the tip of the Georgian Bay formation that pokes into Oakville. It yields its treasures sparingly and you really have to work for it! The rocks were so heavy...I had a bag of goodies plus 3 heavy slabs...barely made it back to the car. I left 4 spectacular slabs that were too heavy to manage...might go back for them when I feel ambitious.

I found this concretion in what I believe to be Lockport dolostone, which is silurian in age. At first I didn't think much of it but then I noticed the surface has a faint texture of cracked shell. I was wondering if this could be a silurian ostracoderm like Tremataspis?

Etobicoke Creek delivers a home run in the bottom of the 9th
markjw posted a topic in Fossil Hunting Trips
I visited Etobicoke Creek again. This time it was near Evans Avenue at a recreational park. There was a softball game going on...the waif thought it might be something called 'rounders' and was intrigued to see how it progressed...I had to drag her the extra 30 meters to the creekbed. Orthocone nautiloids were scattered all over the place, embedded in rocks. The 'she' wanted to find a portion of several segments she could carry home...I get those, but she's never found one. (She eventually brought me a small trilobite, the first I've ever seen). The shell imprints were wonderful, but sometimes worn, and the same species as usual (Bysonnychia and generic bivalves). There were a couple of petrified sponge-like segments, but no good bryozoan colonies. It is fun to find nautiloids because you can sometimes find more than one in a rock (today we tied the record: 4!). Other times they are damaged so you can examine the interior structure. We filled my canvas bag quickly, serenaded by the sound of the softballs being hit off the bat. Finally, near the end of our expedition, the waif saw a segmented rock and tugged it out of the gravel...a portion of a monster cephalapod! Biggest of this genus I've ever seen...and two smaller ones had sheltered in the shell and perished there. What a great time we had.

Is this little ~1.5 cm /half inch disk a trilobite? I've never found one before, and my wife found this today. No detail on bottom...it's all in the image. My attempts to brush off the sand have caused pieces to break off and crumble, so I'm not going to try to expose more. It was in an area full of orthocone nautiloids and byssonichia shell imprints.

Hey guys, new collector looking for some wisdom. Over the past year, I've collected over 150 Fossil specimens from the Chatham-Kent Area. The Majority of my collection is Middle-Devonian Corals and Brachiopods, but I've also found some Petrified Wood and Fossilized Bone. I'm at the point where I can't keep track of my collection and want to start labeling and identifying my fossils for documentation and display purposes. What resources do you guys use to identify fossils you've collected in the field? How accurate can I realistically date things?
