Below, my statistical averages drawn from thousands of Longneck reports worldwide as matched against Hutchinson's SS, Bay of Meil in the Orkneys, 1910
(Plesiosaur skeleton shown at bottom)
Below, Corinthian, Meil Bay, and my composite "Merhorses" (Mine in the brown colouration phase, both redbrown and greenish or olive brown both being regularly noted in such sightings with the reddish brown seen much more commonly. The giraffe-like mottled effect is one infrequent variation on the brownish one) Please note that in opposition to Heuvelmans' "Merhorse" description, the mane is stiff and stands up like a "fin"and the eyes are not large. The "Horns" appear to me to be the same material as the "Fins"
