Georgie87 Posted May 22, 2018 Share Posted May 22, 2018 (edited) These little guys are super common when you break open the shale, along the banks of Lake Ontario, East of Toronto, in Whitby. I have scoured the internet trying to find what this can be, however the only other picture I found was on someones Blog with no identification. Any help would be appreciated, I'm so interested and this fossil hunting/identification may become a new hobby Thank you, Georgie Edited May 22, 2018 by Georgie87 Link to comment Share on other sites More sharing options...
ynot Posted May 22, 2018 Share Posted May 22, 2018 Welcome to TFF! I think You have a trilobite cephalon (head). There is also a small brachiopod it the rock. 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Kane Posted May 22, 2018 Share Posted May 22, 2018 This would be the cranidium of Triarthrus sp. This is Ordovician in age, and fairly common as moults. Image from, Ludvigsen, R.

They are not easy to find complete. They moulted quite a bit, and complete ones would tend to disarticulate easily. This trilobite, and Pseudogygites latimarginatus occurred in deeper seas with less oxygen. Triarthrus had developed some unique adaptations suited to their environment. If you were ever curious about what they would have looked like with their appendages, I highly recommend looking up Beecher's Trilobite Bed. Here is one of several images that show the preservation: 8 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Miocene_Mason Posted May 22, 2018 Share Posted May 22, 2018 Nice little bug, my first trilo was the same genus.

Kane Posted May 22, 2018 Share Posted May 22, 2018 Just as a helpful reference, albeit somewhat dated, the Ludvigsen text I cited above is available online in many formats. The scans are not the best, but they may do the job and provide you with a great deal of basic information on trilobites: https://archive.org/details/fossilsofontario01bolt 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 22, 2018 Share Posted May 22, 2018 Welcome to the Forum. I thought I'd point out the other fossils on your piece. They are almost as cool as the Triarthrus cephalon. 8 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Georgie87 Posted May 26, 2018 Author Share Posted May 26, 2018 Fossildude19 Kane Oh my goodness, thank you so much for all the feedback! I spent an hour or two there this morning and found some more fossils and you've already identified them for me I'm so digging this, I'm planning a couple trips this summer to Hungry Hollow and to Warsaw Caverns to find and see even even more. Last year I developed a passion for finding and identifying wildflowers and plants, and this year it's fossils. The people on this site are amazing!
