I’m going to have to upload more challenging photos for our “Which paleontologist is this?” social media campaign. Morgan Cole (also known as @tmorgan!) guessed it with no effort at all.
The photo (on the FOSSIL’s facebook page) is of Malcom McKenna, my major prof at Columbia U. The photo was taken in 1972 in New Mexico where we collected a pilot series of paleomagnetic samples. This then became my PhD dissertation research topic.
