In summer 2005, the Migros Cooperative Basel financed an exhibition of 18 dinosaurs on the occasion of the 25th anniversary of the city park ‘Park im Grünen’. The biggest object of the exhibition was the 45 meters long Seismosaurus, which has remained in the park for good.
Seismosaurus was an enormous, long-necked, whip-tailed, small-headed dinosaur. It measured about 39-52 m long and was roughly 5.5 m tall [measured from the ground to the top of the shoulder]. It may have weighed about 30 tons and was among the largest land animals that ever lived.
Seismosaurus was an herbivorous sauropod of the late Jurassic period, around 154 to 144 million years past. It was closely related to, or perhaps even the same as, Diplodocus. One incomplete skeleton was discovered in the New Mexican desert 1979.
