Stone Type: Fossil Mako Shark Teeth
Stone Name: Fossil Mako Shark Teeth
Description
Extinct mako shark teeth are fossilized remnants of ancient predatory sharks that once dominated the world’s oceans millions of years ago. Typically streamlined and sharply pointed, these teeth reflect the speed and power of prehistoric mako-like sharks such as Cosmopolitodus hastalis. Their colors range from deep black and charcoal gray to tan, brown, and even bluish hues depending on the mineralization process, often accented with natural enamel sheen and preserved serrations or smooth cutting edges. Each tooth carries a distinct history of the ocean’s distant past, making them highly prized by fossil collectors.
Geological/Chemical Properties
Fossilized mako shark teeth are primarily composed of hydroxyapatite (calcium phosphate), the same mineral found in modern shark teeth and bone. Over millions of years, the original organic material is replaced through permineralization with minerals such as silica, calcite, and iron oxides, which contribute to their varied coloration and preservation. Their hardness is generally around 5 on the Mohs scale, depending on the degree of mineral replacement and fossilization conditions.
Locations Found
Extinct mako shark teeth are commonly found in marine fossil beds around the world, with notable deposits in the United States (particularly California, Florida, and the Carolinas), Morocco, Peru, and parts of Europe. These locations were once ancient seabeds where prehistoric sharks thrived, and sedimentation preserved their teeth over millions of years.
Metaphysical Properties
Extinct shark teeth are often associated with strength, resilience, and primal energy. They are believed to carry the essence of survival, adaptability, and determination from ancient oceans. In metaphysical traditions, they are sometimes used as grounding stones, thought to enhance courage, focus, and protection while helping one connect to deep ancestral and natural forces.
