Coiled into a tight spiral, an ammonite shell shows ribbed whorls and a weathered, stony surface crossed with intricate suture lines. A raised center knob marks the heart of the coil, and the open aperture curls outward at the front of the shell. Cracks and pitted texture make it read like a freshly dug fossil. A striking paleontology model for a classroom fossil lesson, a curiosity shelf or a treasure piece in a tabletop dig site.
