Dino Myths. Among the longest land animals! Diplodocus was a long-necked, whip-tailed giant, measuring about 90 feet (27 m) long with a 26 foot (8 m) long neck and a 45 foot (14 m) long tail, but its head was less than 2 feet long. It was among the longest land animals ever.
Argentinosaurus, known as a sauropod, lived during the middle cretaceous period, 100-90 million years ago. Though it has fewer fragments available, A. fragillimus â a dino in the Amphicoelias family â might be the biggest dinosaur on the block. Based on surviving descriptions of a single fossil bone, researchers estimate that fragillimus may have been 130 to 200 feet long, and may have had a mass of up to 135 tons.
