This paper originally started out as a broad review of chondrichthyan age validation studies. One recurring issue in many of the studies I reviewed was age underestimation, something I had observed during my own research and an issue that had bugged me for a long time.

When I began analysing the data the magnitude and extent of age underestimation took me by surprise, so I decided to rewrite the paper around this topic exclusively. The paper turned out to be rather timely, and generated considerable media interest including from Nature News and National Geographic. I also wrote a guest article about the paper for Southern Fried Science.
