Isotelus maximus (Locke, 1838). Big trilobite pygidium molt and the only partial big molt I have ever found at Mimico creek. Approximately 15 centimetres across. Found in Mimico creek, Toronto, Ontario. Georgian Bay formation, late Ordovician. I found this by accident when I first started fossil hunting at Mimico creek back in October 2013. Shale specimen.
