Ceratites spinosus
Ceratites
An ammonite that lived in the Middle Triassic (approx. 250 million - 220 million years ago). If you magnify the suture line, you can confirm that small serrations are further carved into the saddles.
C. spinosus species.

I was looking for a Ceratites about 10cm in diameter where I could clearly observe the suture lines.
Purchased at the 31st Tokyo International Mineral Fair in June 2018.
