Living Dinosaurs; the Mokele Mbembe

Jurassic Albatross- The Mokele Mbembe, known by different names around Africa is a large dinosaur like monster said to be aggressive, but not carnivorous. It has a long neck and mainly lives in rivers, hibernating in caves during the dry season. With the small head and big body it seems to resemble a sea serpent, but no sea serpent has for columnar legs capable of supporting its weight on dry land. Is the Mokele Mbembe a living Sauropod dinosaur?

The first references to the Mokele Mbembe; the one who stops the flow of rivers, can be found in French missionary Abbé Lievain Bonaventure's 1776 book where he describes animals of the Congo. One passage describes a set of footprints possible referable to this cryptid; "must have been monstrous: the marks of the claws were noted on the ground, and these formed a print about three feet in circumference."

Other documents of footprints show consistency in having been large, at around 3 feet wide and three toed;
1919-1920, expedition into Africa conducted by the Smithsonian Institution; "African guides found large, unexplained tracks along the bank of a river" (Field Guide To Lake Monsters by Loren Coleman and Patrick Huyghe) 1927; Alfred Aloysius Smith, a trader working in Gabon during the 1800's wrights in his memoir Trader Bon where he refers to an unknown creature that leaves round three clawed footprints.
1966; Yvan Ridel photographs a set of three toed footprints near Laubomo.

1909; Big game hunter Carl Hagenbeck in his autobiography Beasts and Men refers to multiple sources including other big game hunters and natives in the Congo area informing him of a creature "half elephant, half dragon" or "some kind of dinosaur, seemingly akin to the brontosaurs".*
1913; German Captain Freiherr von Stein zu Lausnitz includes descriptions of a beast sighted by natives in Cameroon; "The animal is said to be of a brownish-gray color with a smooth skin, its size is approximately that of an elephant; at least that of a hippopotamus. It is said to have a long and very flexible neck and only one tooth but a very long one; some say it is a horn. A few spoke about a long, muscular tail like that of an alligator."
1939; in the German Colonial Gazette (Angola) a letter by Frau Ilse von Nolde describes encounters with a long necked monster called "coye ya menia" ("water lion").1976; botanical expedition into Zaire lead by James Powell, monster called the "n'yamala" described to him by natives.
