DLowe69 Posted October 7, 2020 Share Posted October 7, 2020 Hi - this is my first post to this group. I found this partial trilobite fossil this past summer in Ordovician limestone near Eganville, Ontario, Canada and I am hoping that someone here can help me identify the trilobite species it belongs to. This piece measures 3.5 inches in length by a little over 2.5 inches wide and I believe it is the pygidium and most of the thorax (so a little more than half of the full trilobite). Also, it has a little over 1/2 inch in depth, so it is not completely crushed flat. I would have much rather found a full trilobite - and I do have a full trilobite that I found that I am having prepped, that I will post at a later date - but I am very happy with the size and condition of this sample. I broke it out of the rock in this condition - no prepping has been done to this sample. Any thoughts? 1 Link to comment Share on other sites More sharing options...
FossilDAWG Posted October 7, 2020 Share Posted October 7, 2020 This is an Isotelus. There are several species in the area but Isotelus gigas is the best fit I think. Nice find! I assume the quarry at Eganville is still allowing collectors in, or at least clubs? Don 2 Link to comment Share on other sites More sharing options...
DLowe69 Posted October 7, 2020 Author Share Posted October 7, 2020 I actually found this on a friend's private property, near the river, so I am not sure which quarry you are speaking of. If there is a quarry in the area that allows collectors / clubs, I would certainly be interested... Link to comment Share on other sites More sharing options...
FossilDAWG Posted October 7, 2020 Share Posted October 7, 2020 I think the club @Northern Sharks belongs to has collected there in the past. The quarry is on the same road as the Bonnechere Caves. The articles I read about club trips are a few years old and I don't know the current state of affairs. Also the little museum in Eganville arranges collecting trips for a nominal cost in the summer.

DLowe69 Posted October 7, 2020 Author Share Posted October 7, 2020 Thanks for the info Don. I think most of the club visits in the area were cancelled this year due to Covid. From what I understand, there are many former small quarries in the area (of various types), so I am going to enlist relatives in the area to see if they know anyone with such a property (as I mainly collect minerals). I suspect any private deposits would be much less searched, but that is just an assumption on my part. Link to comment Share on other sites More sharing options...
FossilDAWG Posted October 7, 2020 Share Posted October 7, 2020 There are also area outcrops around Clear Lake but I don't know exactly where as I haven't collected there. Don Link to comment Share on other sites More sharing options...
Northern Sharks Posted October 7, 2020 Share Posted October 7, 2020 I haven't personally collected there, but the Ottawa club may have organized trips there in the past. As you mentioned, this year has been a complete write-off for organized trips. I would certainly consider making the trip there if I knew what could be found, the typical preservation and the frequency of finds. I got spoiled living so close to Lake Simcoe that I never felt the need to drive 4+ hours to hunt in the same formations, but it's been a couple of years since anywhere close to home has allowed collectors in. There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
DLowe69 Posted October 7, 2020 Author Share Posted October 7, 2020 Thanks Sharks. I have found a few other small fossils in the area as well, although I am not sure what they are. I have only been out searching a few times, so the frequency of finds is decent, even if the finds themselves aren't huge. That said, I DO have a larger Isotelus that I am having prepared now, and once that is done I will post pics here. For now, I have posted pics of some of my other finds - again, on private property but I am sure that the finds are similar at other sites in the Eganville area, as you mentioned. 1 Link to comment Share on other sites More sharing options...
DLowe69 Posted October 7, 2020 Author Share Posted October 7, 2020 Looking at it again, what I thought looked like a fish-like fossil MAY be another trilobite, although from the side... Thoughts? Link to comment Share on other sites More sharing options...
Malcolmt Posted October 7, 2020 Share Posted October 7, 2020 There are no fish to be found in that formation. That is also a broken trilobite Link to comment Share on other sites More sharing options...
