Unveiling Callisaurus - A Flexible Necked Sauropod Dinosaur of the Late Jurassic

Callisaurus is a prehistoric genus of herbivorous sauropod dinosaur that lived during the Late Jurassic period, around 155 to 145 million years ago. It was first discovered in 1997 in the Tendaguru Formation of Tanzania and has since been found in other locations in Africa and Europe.

Callisaurus is known for its distinctive neck vertebrae, which were longer than those of other sauropods and had a unique shape that allowed for more flexibility and mobility. It also had a long, heavy tail that it likely used for balance and communication.

Callisaurus was a large animal, with some specimens reaching lengths of over 20 meters (66 feet) and weighing many tons. It likely lived in herds and fed on high-growing plants such as ferns and cycads. Its fossil remains have been found in association with those of other sauropods and theropods, indicating that it coexisted with a diverse range of prehistoric animals.
