Step 1 : Introduction to the question "What species of dinosaur is Barney?"
Barney the Dinosaur is the main protagonist on the television series Barney & Friends. Barney is a six-foot tall, purple Tyrannosaurus rex who conveys educational messages through songs and small dance routines with a friendly, optimistic attitude. Barney was first created in 1987 by Sheryl Leach, who was looking for a way to entertain her then 2 year old son. Patrick was fascinated by a dinosaur exhibit at a museum, particularly the Tyrannosaurus rex. In response, Sheryl made Barney a Tyrannosaurus rex in stuffed animal likeness, who comes to life through a child's imagination.
