Nodosauridae is a family of armored dinosaurs that lived during the Late Cretaceous period. These dinosaurs were herbivorous and characterized by their heavy body, bony plates, and spikes along their backs. They walked on four legs and had a low, stout build, which helped them defend against predators. Members of the Nodosauridae family, such as Nodosaurus and Ankylosaurus, are known for their distinctive armor and club-like tails. They inhabited various environments, primarily in what is now North America and Europe, and their fossils provide valuable insights into the diversity of dinosaur life during their time.
