Ankylosauridae is a family of armored dinosaurs that lived during the Late Cretaceous period. These dinosaurs are known for their distinctive body armor, which consisted of bony plates and spikes that provided protection against predators. They were herbivorous and typically walked on all fours, with a low, heavy body. Members of the Ankylosauridae family, such as Ankylosaurus and Euoplocephalus, had a club-like tail that could be used as a weapon. They inhabited various environments, primarily in what is now North America and Asia. Their unique adaptations made them one of the most recognizable groups of dinosaurs.
