One of the largest land animals of all time is called Argentinosaurus; a sauropod found in Argentina. Why was it so big? How can animal so big survive with enough food and with carnivorous predators around? What did it eat? How did it move? The enormous size of this animal was such that scientists are puzzled at its physiology and its mechanics (movement) – the animal might as well be an impossible creature to exist. Investigate about Argentinosaurus and write an essay about it. The essay must be at least two paragraphs long, and each paragraph must contain at least five sentences (you can write more than two paragraphs and more than five sentences per paragraph if you wish to do so).
