The Komodo dragon of Indonesia is, as Bob and Ray observed, the world’s largest living lizard. Full-grown at ten feet long and 300 pounds, occasionally it eats… people.
Some thousands of years ago, certain monitor lizards in Australia grew to be twice the size of a Komodo dragon. But they were pipsqueaks compared to the Mosasaurus of the Cretaceous Period (or whenever–we don’t want to take such things too seriously).
As you can see in this clip from Jurassic World, the Mosasaur was very, very big–up to thirty or even forty feet long, depending on the species. Mosasaurs are all the rage in dinosaur movies today, and of course their size is exaggerated therein. Closely related to today’s monitor lizards, the Mosasaur was likely the supreme predator of its time. Instead of legs it had flippers, so it had to stay in the water. And no, it was not as big as a New Jersey township.
What hath God wrought? We can only marvel at the scanty remains of these gigantic creatures that are no longer with us. Where they are now, only the God who made them knows. But maybe someday He will tell us.
