Back in October 2012, the British Geological Survey has posted an experimental video on YouTube with 3-D fossil images using red/blue colors. The video lasts over 3 minutes and features over 10 fossils.
In order to look at the video one needs some 3-D glasses. You can make a pair using a PDF template found at NASA's STEREO (Solar TErrestrial RElations Observatory) web site.
I created a pair using the following materials
- card stock paper with printer to print out template
- clear transparency (I used transparent plastic sheet protectors)
- blue Sharpie marker
- red Sharpie marker
- pen knife (optional to cut out eye holes instead of using scissors)
- Scotch tape
Some changes made to the original was to cut out a rectangular area next to the arm pieces to allow it to be taped together better. I drew dashed lines are on the template if you look close at the image.
The Geosciences Collection at the British Geological Survey also have a 3D image of trilobite on their blog site: http://gb3dtypefossils.blogspot.co.uk/2012/10/oers-open-educational-resources_31.html
