JACKSONVILLE, Fla., Nov. 30. -- An enormous reptile, more like the extinct brontosaurus or fabled sea serpent than any living creature, has just been killed by a hunter in this lower Everglades.

Its discovery in this ancient "sea monster" - an ichthyosaur - appears to confirm the animal was warm-blooded, a rarity in reptiles. The preserved skin is smooth, like that of whales or dolphins.
