“As for why Mamenchisaurus among sauropods had relatively even longer necks? Maybe it’s just that much more efficient. “They’re seemingly well engineered to be efficient food gatherers and that’s what the neck allows them to do … plant themselves in one space, eat the vegetation that’s around them and then move only as necessary.
But the lineage of these long-necked dinos was very successful, with different sauropod species appearing early on in the dinosaur era and thriving until their extinction 66 million years ago. The sauropod’s evolutionary adaptations - gigantic size and vegetarian diet - have no modern equivalent, according to the study. However, even at this relatively shallow angle, the neck’s extreme length would still mean the animal’s head could reach heights of around 24.6 to 32.8 feet (7.5 meters to 10 meters) above the ground.
While the posture of some sauropod species might have featured a neck held erect in swanlike fashion, Moore said that biomechanical studies suggested the Mamenchisaurid neck was elevated at an angle of about 20 to 30 degrees above the horizontal. “Presumably, that’s an important mechanism for building such a long neck because that’s going to get quite heavy,” Moore said.
