RIESEN-APATOSAURUS-WIRBEL

Jura, 150 Millionen Jahre
Wyoming, USA
84 × 52 × 25 cm

The plant-eating Apotosaurus belongs to the family of diplodocid sauropod dinosaurs, who roamed the earth in North America during the Late Jurassic period. The name means ‘deceptive lizard’, so-called because the chevron bones are like those of Mosasaurus (Greek ‘apatelos’ of ‘apatelios’ meaning ‘deceptive’, and ‘saurus’ meaning lizard). This dinosaur had an average length of 69–75 ½ ft (23–21 m) and an average weight of 16.4–22.4 tonnes. Othniel Charles Marsh, an American palaeontologist, was the first to describe this species in 1877. He named the first-known species Apotosaurus ajax. Fossils of Apotosauruses were found in the western parts of America such as in Colorado, Wyoming, Oklahoma and Utah.

The cervical vertebrae of the Apotosaurus are less elongated and more heavily constructed than those of the Diplodocus, indicating that they were probably a more robust animal. Its tail was held above ground during normal locomotion, and like that of other diplodocids it might have been used as a whip to create loud noises or even as a sensory organ. Recent studies suggest that certain members of the Diplodocidae family could even whip their tails so forcefully as to produce a noise that would have been loud enough to shatter a human eardrum or scare away a hungry predator. The tail consists of 82 vertebrae.

Isolated sauropod tail vertebrae, like the giant fossil presented here, are seldom preserved intact and without distortion. We are pleased to present this wonderful Apatosaurus vertebra in fantastic condition, with almost no restorations.
