Sea urchin: Lovenia forbesi, Lower Miocene, AUS

Sand dollars (Clypeasteroida) belong to the Irregularia, one of the two subclasses of sea urchins, and have adapted to life in rough coastal and near-shore waters. Their flat shape offers them little water resistance and the side arms of their intestines are filled with the heaviest pebbles they can find and swallow.Age: PlioceneLocality: Baja California, MexicoSize: 8 cmColors in product photos may differ slightly from those of the original specimen due to technical reasons.The photos are for reference only.

Small, completely preserved sea urchins without spines. As the spines are only attached to the body with a thin layer of tissue, they quickly fall off after the death of the animal and are carried away by the current. However, the body is preserved with the finest details, such as the spine bases or the pores on the ambulacral plates.Age: CretaceousLocality: MoroccoSize: approx. 1.5 cmThe photo is a sample image.
