Sue at The Field Museum

Facts, Theory, Speculation

Facts are things we know are true because we can:

	see, smell, hear, taste, or touch them,
	measure them,
	manipulate them,
	and show them to others.

The facts about Sue, and all other dinosaurs, come from studying the parts that can be directly observed--the fossilized bones or the sediments they were buried and fossilized in.

Fact: Sue is the world’s most complete T. rex.
