Here are a couple more I picked out of the Arkona mud. I put my guesses at the bottom but would like to see what you guys think. #1 These range from 5-10 mm The shape is roughly a 3 sided pyramid with 120/30/30 degree angles Some are pyritized but the others have a very faint lateral ridge pattern #2 My guess: #1 - Conulariid #2 - Fragment of a Devonaster arm Edit: adding one I forgot #3

Hey guys. I've been browsing this forum for a couple weeks now so decided to post. I am located in Mississauga Ontario. I spent a lot of time walking my dog near the etobicoke creek this summer and rediscovered my interest in fossil hunting. Other than the creek, I made drive up to Craigleith Ontario last weekend, and Whitby Ontario a couple times before. No spectacular finds yet but enough encouragement to keep looking. I would like to do some digging in a quarry but I assume only organized groups are allowed. If anyone has info on where to get involved that would be awesome! I've got no problem driving a couple hours on most weekends to meet up if anyone is planning a trip (hopefully even this season if winter doesnt hit too soon). Feel free to shoot me a message! I'll post some pictures after work of what I've found, for now here's my dog:
-
Okay, so i recently ordered and received this "tooth" from a 100% trusted seller. It was sold to me as a chirostenotes tooth but that doesn't add up cause i thought they were jawless. There was a jaw specimen found but later redescribed as Richardoestesia. Maybe its another type of small oviraptor? Does anyone know what this is? (The tooth is only 3mm long so it was really hard to take a picture of it and only 4mb allowed to upload pics so just ask and i'll reply with more).
-
Hi folks! Thought I might try leaning on the expertise of the forum gurus - I've owned this tooth for a few years and would like to hear any opinions of what the specimen should be classed as. It was sold as Daspletosaurus Torosus, but I'm aware of how hard it can be to label Tyrannosaur teeth (or just leave them as 'indet'). The tooth originated from Alberta, Canada. As it isn't the clearest to see, the denticles (which are very fine and equal in size on both sides) on the anterior edge curve off to the right (viewing the tooth face on), whilst the posterior serrated line is straight. PS: Apologies for the quality of photos too...my phone doesn't enjoy photographing anything magnified.

Hi, I found this little gem in Southern Alberta. Any ideas about what creature it looks like it might belong to?

Fossil hunting (with camera) in Churchill, Manitoba, Canada
digit posted a topic in Fossil Hunting Trips
Tammy and I spent our anniversary in Churchill, Manitoba (Canada) this year in an effort to see both Polar Bears by day and the Aurora Borealis by night. We succeeded in the first half of this mission but cloudy skies that had Churchill socked-in for the duration of our stay occluded any views we had of the nighttime sky (actually, the daytime sky as well--we never saw the sun while we were there). We had learned about Isotelus rex (the world's current record holder for most enormous species of trilobite) and were able to visit the specimen collected in Churchill when we visited the Manitoba Museum in Winnipeg: http://www.thefossilforum.com/index.php?/topic/78783-manitoba-museum-winnipeg/ We knew that the beaches would have some nice outcrops of Late Ordovician fossils where the giant trilobite was discovered and we looked for an opportunity to pay homage to I. rex with a pilgrimage to the type locality on our trip. Walking the beaches during Polar Bear season requires some caution and some extra preparation--like some sled dogs to help alert us to the presence of bears and a guide (Gerald, the owner of our B&B in Churchill--Blue Sky Bed & Sled). There are large boulders of Precambrian metagreywacke (aka "Churchill Quartzite") that are big enough for Polar Bears to hide among and pop-out with little notice and these limited sight lines make it necessary to take extra precautions when fossil hunting (bear dogs and shotguns are not normally required fossil hunting gear). It didn't take us too long poking around the lighter colored Ordovician limestone cobbles to start spotting fossils. Surfaces with dense deposits of bivalves were pretty easy to spot. There are apparently both similar looking bivalves and brachiopods occurring in this outcrop and we didn't inspect the fossils closely enough (it was quite chilly out with the stiff breeze) to decide which we were seeing. I'm not familiar enough with these types of fossils to be able to quickly distinguish. We also saw some evidence of gastropod steinkerns but they were not nearly as common as the bivalve/brachipod type of fossils. We also saw an interesting patterned rock that may be a fossil, ichnofossil, or maybe simply something geological and abiotic. It was pretty wild looking whatever it was. We didn't spot any rugose (horn) corals but did see what appeared to be some tabulate corals and one colonial coral that forms a tessellated pattern of what look like chain links--quite distinctive. We saw many occurrences of this finely patterned honeycomb-like fossil which I assume is a colonial (tabulate) coral and not something like a bryozoan or a Receptactulites. I need to do a bit more research online to see if I can't narrow down what types of fossils we were seeing. A little searching netted some of the sightings of the chambered linear fossils of some orthoconic cephalopods. These seem to catch the interest of most of the locals and several of them have nice specimens of these fossils (though few have any idea what they actually are/were). I tried to look around for some of the in situ slabs of limestone where trilobite fossils or the ichnofossil trails of the same might be found. I did spot some nice flat pavements after a bit of searching but could not locate any of the (very rare) giant trilobites for a photo. Pictured above are our Polar Bear alert dogs Sony and Gracie enjoying a visit to the beach to run around and splash in the frigid waters. Cheers. -Ken

I may have posted some of these before but never got answers, and now it's been a while and probably the pics were not very good anyway, so am trying again. They're still not very good, even tho' taken in the sunlight. I don't know what to do about that. Anyway, we acquired these thru old rockhounds years ago and either they or we failed to record the info, and now it's lost. Some of it is nice stuff at least from a lapidary or display-piece standpoint, but would be nice if someone recognized them and could tell me where they likely came from. All I am willing to bet on is Western states or provinces. There will be more when I get it dug out of the chaos and photo'd. We recently had to empty my 'rock shed'/water tank shed to have larger tanks put in. What a job... Possible maple: The small slab came with the word 'maple' on it, and it looks to be similar to the larger piece standing next to it, and possibly the smaller chunk beside that. It does look like maple..

Tammy and I had to stop in Winnipeg on our way up to Churchill further north in the province (with hopes of seeing Polar Bears and the Aurora Borealis for our anniversary). While doing a little research on Churchill I discovered it is the type locality for the world's largest trilobite. Now I'm not talking something that is a little bit bigger than some of the really large Paradoxides or Cambropallas trilobites you see from Morocco (fake or otherwise). I'm talking taking trilobites to a whole new extreme (but more on that later). We flew from Miami to Winnipeg on a flight that connected through Toronto. I really don't know why the computerized reservation systems conjured up by these airlines let you make routes with tight connections--but they DO! We planned on spending an extra day in Winnipeg as the tight connection in Toronto seemed highly optimistic at best. We were late out of Miami when the first officer didn't show up and they had to call in a substitute. The pilots didn't even try to make up the delay in the air and we arrived well behind schedule. I doubt that we could have made the connection anyway (> 1 hour) having to go through customs/immigration and travel to the far reaches of the airport to catch the connecting flight. Our flight had left before we even cleared processing in Canada but we were able to book a follow-up flight a few hours later. It still took us over 2.5 hours to reach our gate for the connecting flight and so (without the aid of teleportation--or maybe a large canon) we were doomed from the start. We got in later but well in time to make our exceedingly expensive flight to Churchill. The rail line is down (washed out this spring) and there are no roads up to this isolated corner of Manitoba. I had heard that a truly enormous trilobite had been discovered in Churchill and that it currently resides in the Manitoba Museum so promptly after breakfast we grabbed a cab to the city center and arrived at the unassuming (from the outside) museum. We didn't even make it inside before my gaze was captured by the beautiful stone slabs that clad this building's exterior. Soon I was to learn that this was the locally famous Late Ordovician (~450 myo) Tyndall Stone. The interesting two-toned appearance of this dolomitic limestone is said to be ichnofossils from some sort of burrowing animal. It really makes the stone quite striking from far away with this unusual patterning. I can see why they have used this stone to face the surfaces of many prominent buildings in Canada (and abroad). https://en.wikipedia.org/wiki/Tyndall_stone

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

Albertavenator curriei: New Species of Bird-Like Dinosaur Identified in Canada
haventbaptized posted a topic in Fossil News
About 71 million years ago, a feathered dinosaur that was too big to fly rambled through parts of North America, likely using its serrated teeth to gobble down meat and veggies, a new study finds. The newly named paleo-beast is a type of troodontid, a bird-like, bipedal dinosaur that's a close relation of Velociraptor. Researchers named it Albertavenator curriei, in honor of the Canadian province where it was found (Alberta), its stalking proclivity (venator is Latin for "hunter") and Philip Currie, a renowned Canadian paleontologist. https://www.livescience.com/59815-stalker-velociraptor-relative-discovered.html https://www.sciencedaily.com/releases/2017/07/170717091023.htm -

Hey everyone. So I am new to fossil hunting. Like completely new. I am taking a geology class and one of my assignments includes going fossil hunting! So fun. I have gone out twice and feel like I'm having no luck. However at the last minute I came across this. I am really not sure if it's just rock or something more. Since I am completely new at this hoping someone can help me. Thanks in advance for any insight.

Hello! Someone I know found this rock close to his house. The rock is very hard, can't make no scratch on it. I though it could be a fossil, like a limpet track or I don't know...? Does someone know what it is? Thank you! Fossile patelle?.pdf
