Smith, a scientist at the University of Pennsylvania, says this particular skeleton was probably torn apart by sharp-toothed predators as it lay on the beach of a warm tropical sea. He found only a few bones, but they were enough to calculate the dinosaur's gargantuan size at 80 to 100 feet long and weighing 60-70 tons. The find solves another mystery: what those previously discovered predators three different kinds, each (at 50 feet) bigger than Tyrannosaurus Rex were dining on during their prehistoric stay on the old North African coast. Said Smith: "Now we've found a 90-ton steak that they were eating."
Digging for archaeological paydirt in what is now the Sahara Desert, scientists have unearthed the fossilized bones of the second-largest dinosaur ever to walk the earth. Dubbed Paralititan stromeri (the first name means "tidal giant"; the second refers to Ernst Stromer, a geologist who found dinosaur fossils in the area in the 1930s and took them to Germany, only to have them destroyed by Allied bombing in WWII) this long-necked, plodding sauropod munched on lush ferns and trees in an area that 90 million years ago was, according to discoverer Joshua B. Smith "dinosaur heaven."
