first guess without reading anything would be doubtfull! sounds like someones read a jurassic park book and put their ideas down.
Would be cool if there was one tho, and if there was one why not more?
nice idea!

In the jungles of central Africa countries of Congo, Cameroon, and Gabon are reports of animal an animal with a long neck, a long tail, and rounded shape tracks with three claws. The closest known animal that has these characteristics is a sauropod dinosaur.
When some of the local people of the Likouala region would draw in the dirt or sand a representation of Mokele-mbembe they drew the shape of a sauropod dinosaur. Then when they were shown a picture of a sauropod dinosaur they said that picture is Mokele-mbembe.
