Fish Fossil - Syngnathus sp. (Pipefish) Sphalerite or the formation of equallyPipefish are a widespread group of tropical marine and freshwater fish most closely related to the more well known seahorses. Their unique elongated and heavily armored bodies along with their tube like snouts make pipefish, both extinct and modern, almost unmistakable for any other species. These well preserved and larger sized fossils originate from the Monterey Formation in California, from the middle Miocene around 12 16 million years ago. Each
