Moabosaurus (meaning "Moab reptile") is a genus of turiasaurian sauropod dinosaur from the Early Cretaceous Cedar Mountain Formation of Utah, United States.

The quarry produced parts of at least 18 individuals of Moabosaurus based on the number of braincases present, totalling over 5,500 bones.

Insects, probably beetle larvae, consumed portions of the bones that were in contact with the ground, as evidenced by burrows and mandible marks.

[2] Later, the bones were transported a short distance by a stream and buried in sediments reworked from the underlying Morrison Formation.

[4] The Dalton Wells quarry has also yielded specimens of Venenosaurus (a brachiosaurid sauropod), the theropod dinosaurs Utahraptor and Nedcolbertia, plus a tall-spined iguanodontian,[5] and the ankylosaurian Gastonia.
