1.7" Serratolamna Fossil Shark Tooth

This is a fossil tooth of the shark Serratolamna. Serratolamna is probably the most ornate of the mackerel sharks and has very distinctive and large double side cusps. Teeth of this quality are hard to find because these longer side cusps are so frequently damaged. It's a really cool type of fossil shark tooth from the phosphate mines of Morocco.
