Complete Treptoceras crebiseptum
Complete specimen of a late Ordovician cephalopod Treptoceras crebiseptum, even with the living chamber intact. The length is appr. 37 cm. From the Mimico creek, Georgian Bay formation, Ontario. Specimen found in shale and my first complete one!! I usually find small fragments of the phragmocone at Mimico creek. Also keep in mind specimens found in shale are preserved squashed, compared to the ones preserved in limestone they are preserved in their original shape.
