To view this X3D (cross-eyed 3D) image in 3 dimensions, click on the image to enlarge it. Get back from your computer screen about 6 to 8 feet. Put a finger in front of your nose about 2 to 3 feet. Look at your finger to cross your eyes. When the distance from your finger to your eyes is just right, you will then see 3 images. The image in the center is 3D once your brain blends the images. The colored image frame is added to aid aligning the two images.
You may see the T. rex bird relationship if you notice the "U" shaped wishbone at the top front of the chest.
I always loved this one. It's been in my favourites list for ages, but I realized I never commented!
