Answer 1

Spinosaurus was a genus in the family Spinosauridae. Spinosauridae belonged to the clades, in order from smallest to largest, Megalosauria, Orionides, Tetanurae, Averostra, and Neotheropoda. Neotheropoda was the clade that included most species belonging to the Theropoda clade, which in turn belonged to the Eusaurischia clade of the order Saurischia, also known as the lizard hipped dinosaurs. Saurischia belonged to the Dinosauria superorder, and Dinosauria belonged to the Archosauria clade of the Crurotarsi clade. In turn, Crurotarsi belonged to the class Reptilia. Reptiles belong to the subphylum Chordata, phylum vertebrata, and finally the kingdom Animalia.
