ammo-, amm-

An order of dinosaurs that were omnivorous: The order of Ammosaurus included the “sand (or sand-stone) lizard” from Late Triassic or Early Jurassic Connecticut and Arizona, USA.

Only the back half of the specimen was rescued from a quarry in the Connecticut River Valley because the front half was already sawed into blocks to build South Manchester Bridge in Manchester. The bridge was demolished in 1969, and researchers at Yale were able to retrieve some additional fossil material.

Named by Othniel Charles Marsh (1831-1899) in 1891.

The treatment of a person's body with hot sand; psammotherapy: Susan was advised to go to a therapist for ammotherapy, or simply sand bathing, for her ongoing ailment. She would be submerged in hot desert sand and the sand would distribute the heat evenly over her body and absorb her perspiration.
