Subfamily Neptunosaurinae
Neptune (also known as Neosaurus, Tyrosaurus meaning "lizard with a globular nose"), in the Alabama Eutaw Formation and Mooreville Cretaceous Formation, Neptune preferred shallow water, near-shore environments; But in other environments, Neptunosaurus adapted to deep-water environments, such as the Neobrala chalk in the western United States. The main food of Neptunosaurus was plesiosaurs , swordfish , ammonites , dusk birds , and other small mosasaurs , and fossils of marine animals of the time have been found in its stomach , and Neptune was the apex predator in the western inland seaways of the Late Cretaceous. In order to maintain the advantage of top sea climbing, Neptune also specialized a cylindrical premaxilla that other mosasaurs did not have, which could be used to ram and unstun prey, and could also be used to fight within species. In addition, many documentaries of the mosasaur genus are actually based on the genus Neptunosaurus, rather than the real mosasaur genus.

Since the BBC's satellite Ankylosaurus has led to some people who do not know much about paleontology, think that Ankylosaurus is a very powerful carnivorous dinosaur nemesis, and later Ankylosaurus' tail hammer has been proved to be unable to swing in a large way, and the strength is not enough to hurt the size of large dinosaurs, and a bunch of people say that stacked armor is a dead end, and Ankylosaurus is waste or something. In fact, the species of ankylosaurus did not fail, because at that time ceratosaurs and hadrosaurs occupied the main ecological niche of herbivores, and ankylosaurs were inferior to them in number and diversity, but they also avoided a head-on confrontation with tyrannosaurs. Top predators like the Tyrannosaurus were basically attracted to Triceratops and Edmonton Dragons, and Ankylosaurus had enough accessories to deal with secondary predators like Dwarf Tyrannosaurus and Dakota Raptor, wouldn't that be considered a success? Although ankylosaurs did not have the same huge numbers as Ceratops and Platysaurus, their strategy was enough to ensure that their population did not die, was this not successful enough?
