Our understanding of dinosaur biology is changing all the time, both with new fossil discoveries and new technologies with which to interpret them. Although some argue in favor of conspiracy theories, we are beginning to put together a solid understanding of what these massive animals probably looked like. In time, we'll learn even more, and our collective mental image will adapt once again; nonetheless, the picture is clearer than ever before.
Through clever use of comparative biology, pigment analysis, and powerful new X-rays, paleontologists have a renewed confidence about the physical appearance of dinosaurs. This includes everything from their colors to their eating behaviors to the shapes of their tongues. The results can be as impressive as they are strange.
