Vedecká klasifikácia prevažne podľa tohto článku

Spinosaury (neformálne spinosauridy, lat. Spinosauridae) boli veľké až obrovské mäsožravé dinosaury z obdobia skorej kriedy (pred asi 125 až 95 miliónmi rokov). Disponovali pretiahnutou, pomerne úzkou lebkou, ktorá výrazne pripomína lebky krokodílov. Trojprsté predné končatiny mali opatrené veľkými zahnutými pazúrmi a predpokladá sa, že sa zdržovali prevažne pri brehoch riek, kde lovili nepozorné ryby.[1] Ich pozostatky boli dosiaľ nájdené v Európe, Afrike a Južnej Amerike. Najznámejší zo všetkých spinosaurov je rod Spinosaurus.
