Viewing 3-D Fossil Images


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
  • scissors
  • 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

3D Laser Scanned Fossil Images


The British Geological Survey has posted on YouTube a nice video showing some of the fossils from their collection of around three million specimens. Fossils contained in the collection range from time from the Neoproterozoic to modern times. At 51 seconds into the video the Precambrian Charnia masoni is shown which is Britain's oldest animal. Learn more about it this Wikipedia page.
