|Eyewitness sketch of the Hagan carcass (middle) and images of the two most plausible identities (above and below).|
(Part 4 can be found here)In this, the final installment of the Hagan Carcass Comparison Series, I will review two possible hypotheses which I have formulated after researching possible identities for the enigmatic carcass reported by Ms. Julie Hagan. The first hypothesis involves a scenario of misidentification: the carcass being that of a known species. Commenters have suggested a wide variety of animal species which could have been misidentified in this case, from oddly decomposed sturgeons to false catsharks. While many aspects of sturgeon morphology are in disagreement with those described for the Hagan Carcass, false catsharks can grow to a length of ten feet and can have a similar appearance to the carcass with their wide angular heads and other body features1. These sharks are also rare deep-water fish1, and thus would likely not be identified by the average person if found swollen and slightly decomposed on shore.
Comparison between Ms. Hagan's sketches of the Hagan carcass (middle), an image of a false catshark carcass (top), and several images of decomposing sturgeon carcasses (bottom).
