You know that Megalosaurids evolved into Spinosaurids? they were normal predators then they became fish eaters(well mostly ate fish) and Suchomimus had curved serrated teeth and big shoulders and hollow bones so it's more of a meat eater than a fish eater and Spinosaurus and Baryonyx had Dense bones i'm not sure about other Spinosaurids and also they had hollow and conical teeth and because Megalosaurids became Spinosaurids maybe Suchomimus is not fully a common Spinosaurid but it still has Megalosaurid traits but also Spinosaurid traits
