Suddenly Glen realized what he was seeing. These must be Clod-fawns. They were huge! Jenna had been conservative in her description of seven foot lizards. These lizards walked on two legs and used their tails for balance. Covered from head to toe with bright, neon green scales, they reminded him vaguely of a tyrannosaurus rex, only with well-muscled, usable arms attached on the sides of their shoulders.
The helmets they wore were shaped wrong for any dinosaur. Glen rather thought they would fit on his own head, though the squarish corners might be uncomfortable. Their faces were different, too; he could see them through the helmet’s clear front covering. They were definitely lizardish; red eyes with a slit for a mouth, and absolutely nothing where the nose should have been. Glen wondered absently what they would do if they needed to wear glasses, with no nose to hold them up.
They wore black bits of stuff strapped to various parts of their bodies, and Glen recalled Jenna saying something about blast armor. It certainly looked like armor. Not the kind knights used to wear; more like a Roman soldier’s. Breast plates and back plates, helmets, and guards on the forearms and shins.
Other than the helmets and armor, they wore no other clothing. Apparently the lizards had no problem with nudity, but then, Glen couldn’t recognize anything that modesty should prompt them to cover. (from Assignment to Earth by Scott Ashby) http://tinyurl.com/kr2uyh5
