ເລື່ອງໜ້າຮູ້ມ່ວນໆ
Styxosaurus had an extremely long neck, with over 60 vertebrae, making it one of the longest necks of any animal that ever lived.2
It lived in the Western Interior Seaway, a huge inland sea that split North America in two during the time of the dinosaurs.2
Some fossils of Styxosaurus were once thought to belong to a different animal called Hydralmosaurus, but scientists now think they are the same.2
