Lindsay Selby has an interesting new post on unidentified animals in South America, which in part states:
"There have been reports since the 1800’s of living dinosaurs in Bolivia and other South American countries. At the end of the 19th century Scientific American recorded the following remarkable events: "The Brazilian Minister at La Paz, Bolivia, had remitted to the Minister of Foreign Affairs in Rio photographs of drawings of an extraordinary saurian killed on the Beni after receiving thirty-six balls. By order of the President of Bolivia the dried body, which had been preserved in Asuncion, was sent to La Paz." The "monster" was reported to be twelve meters long (39 ft) from snout to point of the tail, which latter was flattened. It’s head resemblance the head of a dog and its legs were short, ending with formidable claws. The legs and abdomen sported a kind of scale armour, and all the back is protected by a still thicker and double cuirass, starting from behind the ears of the anterior head, and continuing to the tail. The neck is long, and the belly large and almost dragging on the ground."( "A Bolivian Saurian," Scientific American, 49:3, 1883.)
"It sounds like a crocodile like species but reports continued to trickle in. Franz Hermann Schmidt, a German traveller told of an encounter in 1907. Schmidt was travelling along the Solimoes River in Colombia along with Captain Rudolph Pfleng. Pfleng and Schmidt encountered some huge tracks along the shores of a small lake and trees nearby were stripped to a height of 14 feet. The following day, Schmidt, Pfleng and their Indian guides saw a dark shape among the trees on the shore. A large tapir-like head was suspended on a snakelike neck more than 10 feet above the ground. The creature advanced towards the party but did not seem agitated. It was some 8 or 9 feet tall, with clawed flippers in place of legs. The explorers opened fire on the beast and it dove back into the water. Sounds Like a strange sight, almost giraffe like head and neck."
