The first fossils of Tenontosaurus were discovered in 1903 in Montana. Tenontosaurus measured 6.5 to 8 meters long and weighed between 1 to 2 tons. It had a particularly long tail, which was stiffened by bony tendons much like its back was. Rebor has created a corpse museum class replica of this mighty dinosaur, it measures approx. 23 x 9.5 x 3.5 cm. It comes with a polystone base that can be combined with the Acrocanthus replica (available separately).
