This is an image of a thin section of a dinosaur bone preserved in clear agate. This photo was taken by Mr. Ted Kinsman from sciencephotography.com, Rochester, New York, USA. The magnification is 10x and the technique used is focus stacking. Reading the technique as focus stacking made me wonder what is focus stacking? After some research I found out it combines multiple photos taken at different focus distances that then shows a greater depth of field than an individual photo. (http://en.wikipedia.org/wiki/Focus_stacking) Some other questions I had was, did we find anything from this dinosaur? How old is the dinosaur? Can this help us expand in research?

  1. That's very interesting to see such a different looking bone that we normally see and its very cool that it was preserved in clear agate. Focus stacking seems to be a very helpful technique to see such depth,
