An apparent eye-witness account is given by Aristotle in his work Historia Animalium on natural history. Strabo makes reference to an eyewitness account of a dead sea creature sighted by Poseidonius on the coast of the northern Levant. He reports the following: "As for the plains, the first, beginning at the sea, is called Macras, or Macra-Plain. Here, as reported by Poseidonius, was seen the fallen dragon, the corpse of which was about a plethrum [30 m or 100 feet] in length, and so bulky that horsemen standing by it on either side could not see one another, and its jaws were large enough to admit a man on horseback, and each flake of its horny scales exceeded an oblong shield in length."[7] The creature was seen sometime between 130 and 51 BC.
