Maybe I'm imagining patterns. Coral? Geological process? Found along Lake Ontario, among other whitish rocks from elsewhere, most very fossiliferous, arranged along the shore.

Was examining several of my rocks (sandstone & mudstone) that have light-coloured spots, such as the images of 3 rocks below. I read "Reduction Spots in the Mesoproterozoic Age: implications for life in the early terrestrial record" (Spinks, Parnell, Bowden) -- well, the little that I could understand -- and was wondering whether any of these 3 rocks might be an example of this. The spots in my rocks do not seem to have the "dark concretionary cores" that the article says are often present in the spots, but I was curious to know more. I'm having doubts but thought I'd ask. Thanks for any ideas. Rock #1: Rock #2: Rock #3:

Found a couple of days ago along Lake Ontario, in Toronto: This is a follow-up to my previous post some weeks ago: I stand corrected about the "graptilites" part! Turns out the fossils on that rock were bifoliate bryozoan. So I'm wondering if the present specimen submitted here is also a bifoliate bryozoan. Thank you!

Excited to find this fossil-rich rock, which seems to have graptolites (my first). Any thoughts on ID?
Rogue Embryo posted a topic in Fossil ID
It's been a while since I've posted here, but recently I found a small rock that's covered by fossils that are less familiar to me than the crinoids and cephalopods that I often find near Toronto. I think some are graptolites, but would appreciate any help with ID. Thanks very much!- 9 replies

Two more that stump me! The first is from Humber River, and the second was found on the beach of Lake Ontario, in Toronto. 1. I see iron deposits, I assume. Judging from the staining and the smell it leaves on my fingers! But the little whorls are confusing. As are the little flat edges that sparkle and that serrated? Indentation. I suppose 'serrated' isn't the word, but I can't quite describe it! Seems like a weird conglomerate of different things. (Fear not. The needle is used for depositing water into my ant colonies but I figured it was a good way to measure as it doubles as a tiny ruler.) 2. I'm fairly certain this is a just a rock, but I'm not sure what's going on with the shining bits. Pyrite perhaps? Though pyrite isn't a fossil, of course. Hopefully this isn't an irritating ask! If it is, I'll happily refrain from any further rock shenanigans.

Found this along Lake Ontario in Toronto. If this is a coral colony, is it possible to tell what kind? The spotted pattern occurs inside the rock, too, evidenced by the last image of a break. It doesn't look much like the scores of coral fossil-rocks I've seen around here.

I found this on a Lake Ontario beach in Toronto. Is it Ordovician (the ag e of most fossils in this area)? Or something else?

Greetings everybody! While I was on my fishing trip last weekend I took some time to look for fossils. I collected at a couple of creeks exposing the Middle Ordovician Trenton Group in North-Central NY. I found lots of trilo-bits and other goodies! Enjoy

Been having some heavy wind and storms. Found this on the shore of Lake Ontario in Henderson Harbor, NY. From what I have researched online and previous posts, thinking this is Spyroceras? Decent size too. Very happy with this and found it in a couple pieces so had to glue back together. Can anyone confirm or help to to ID? Rock is mostly Shale and Limestone. Area Ordovician in age from what I have been told.

Hey everyone, New member here, my husband and I just got started fossil hunting on the shores of Lake Ontario near Courtice Ontario and found lots of these trilobite looking things in between shake layers but we are having a really hard time figuring out what exactly it is. Any help would be greatly appreciated. Thanks in advance!

I found these today in Henderson Harbor NY along the shore. One looks like a plant of some kind and the other a cephalopods of some kind? No clue as I've never found something like this and can't find anything similar online for the plant like one. Any help would be amazing and thank you!

This conical, segmented, fossil was picked up off the shores of Lake Ontario in rocks that contain a lot of bryozoan and crinoid fragments. I think it is Devonian, but could someone help me confirm that, and help me understand what this fossil might be?

Hi Everyone, My husband and I found this little wonder while walking on the shore of Lake Ontario right outside of Toronto today. I am attaching the best pic I can with the space restrictions, I hope it is enough. To describe a little further the image in the pic, the interior of the ridges are crystalized, almost like a geode and you can see a raised "spine" that runs down the center. We don't know what it is, how old it is and if its a rare find or a common item for the area. We're not familiar with fossils and are not from the area. Any information would be greatly appreciated. Thanks in advance!

I found this on the beach I am trying to find out what it is. It weighs nearly 5 lbs. Measure 7" by 7" at the biggest part.

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.
