Last weekend was almost surreal; I've always been looking to go hunting for ammonites at some point, but the opportunity finally arose while I visited Hokkaido, Japan last week. Ammonites from Hokkaido have always been captivating; they definitely represent some of the best the Asian continent has to offer, and are also known to produce the biggest in the continent. In the far north of Hokkaido, iridescent ammonites could be found, while in the central region, heteromorphs are more common. In very rare occasions across the island, titanic ammonites are lifted out of the streams. On the 13th of July, my first day in the Hokkaido Prefecture, I met up with a local friend in Sapporo to go hunting. He's had quite a few years of experience, and is very knowledgeable about the ammonites of Hokkaido. After a few hours of driving, we went off the road and into the Hokkaido wilderness to search for ammonites. Not long after our arrival at the creek, we started finding clues of ammonite-bearing rock.
