[UV, FL] Enhancing the visibility of fossil cephalopods soft tissue structures

I had the honor to work with Neal Larson (yeah, THAT Neal Larson who discovered SUE, the T-Rex, with his brother Peter) on a paper on fossilized cephalopods found in Hajoula, Lebanon. I used my remapping technology consisting of a visible image (A), a UV stimulated visible fluorescence image (B) to enhance the visibility of preserved soft tissue structures (C) by combining them into one multispectral image.

Should someone be interested in the paper, the full title is:

Another example of the same technique, shots I did with a squid fossil I have here from the Upper Cretaceous period, ca 90 million years old.

There is a follow up to this one HERE.

Stay tuned, more will follow on that fascinating subject...
