Bactrosaurus

club lizard (or "staff lizard")

• baktron · Greek · club, staff, cane
• sauros · Greek · lizard

The name comes from the Greek "baktron" (staff or club) and "sauros" (lizard). Gilmore chose it because the neural spines on the animal's vertebrae are rod-like, resembling clubs or staffs, rather than because of the skull or body shape.
