FULL STORY here: bit.ly/StegosaurusYT

The final adult Stegosaurus stood sixteen feet tall and measured twenty-six feet from nose to tail; at that time, it was the second-largest character ever created by Stan Winston Studio.

To reduce costs and weight, the crew built the Stego’s head and neck, as well as the section from its rump to the tip of its tail, leaving a gap in the middle. The plan was for Steven Spielberg to frame his shots so that either the Stego’s head or its backside would be in the frame — never the whole animal, head to tail.

Hydraulics and a computer-linked telemetry device controlled the head, neck, and tail, while radio controllers operated facial articulation. The sixteen plates along the Stegosaurus' spine were individually rigged with hydraulic cylinders, run off a mixing board with slider controls.
