Claiming the extinction of anything requires absolute omniscient knowledge over the whole earth and every living thing at the same moment in time, and that's an arrogant and slippery position to hold. They claimed the Coelacanth was extinct 325 million years ago, but they found it a few decades ago off the coast of Australia.
And what did the evolutionists say? "Wow, it must have survive for 325 million years!" It's an unfalsifiable theory, which means it's not science.

The Likouala Swamp is about 55,000 square miles and about 85% unexplored. There are many very dangerous creatures in the jungle, including deadly insects, deadly animals, and harsh uninhabitable conditions for mankind. Considering the near impossibility to bring camera film and electronic equipment on expeditions due to the high humidity levels, it's no wonder why it hasn't yet been explored.
Roy Mackel, an evolutionary biologist and professor of zoology, raised a quarter of a million dollars to go on an expedition into the Congo jungle to find a creature referred to by the surrounding inhabitants as, "Mokele-mbembe." He came back from that expedition, and wrote a book called:
A Living Dinosaur? The Search for Mokele-Mbembe. Roy Mackel, an evolutionist, claims he has seen a living dinosaur.
Roy Mackel picked up some guides and visited different tribes that would venture into the Congo. He asked one tribe, "What is Mokele-Mbembe?" The tribesman drew him a creature that looked exactly like a brachiosaurus. So to make sure no one was conspiring to feed him a story, he visited another tribe, drew a picture of a brachiosaurus, and asked, "What is this creature?" They all answered, "Mokele-Mbembe!"
Mokele-mbembe means 'stopper of rivers'. Dr. Mackel was also told that if he came to a place along the river where there were no hippos or crocodiles, mokele-mbembe probably lives there. Though the brachiosaurus is still not as large as it used to be, it can, according to the tribesman, get large enough that when it traverses a small river, it actually stops it from flowing.
