    en.wikipedia.org/wiki/Spinosauridae

    The teeth of spinosaurids were conical, with an oval to circular cross section and either absent or very fine serrations. Their teeth ranged from slightly recurved, such as those of Baryonyx and Suchomimus, to straight, such as those of Spinosaurus and Siamosaurus, and the crown was often ornamented with longitudinal grooves or ridges. [35] [38]

    The tip of the snout was enlarged sideways and carried a "terminal rosette" of longer teeth, seven per side in the premaxillae and about the same number in the corresponding part of the lower jaw. Further back, there were at least 22 teeth per upper jaw side in the maxilla, while the entire lower jaw side carried 32 teeth in the dentary bone. [1]

    Diagram comparing the holotype tooth (first from left) with other spinosaurid teeth from Asia. Fossil theropod teeth are typically identified by attributes such as the proportions, size, and curvature of the crown, as well as the presence and/or shape of the denticles (serrations). [39] The holotype of S.

    Diagram illustrating skull elements from Irritator (bottom) and other spinosaurids, comparing the relative positions of the external nares, or bony nostrils, (labeled e.n.) In 1998, Sereno and colleagues defined two subfamilies within the Spinosauridae based on craniodental (skull and tooth) characteristics.

    Annotated diagram of the reconstructed skull Annotated diagram of the reconstructed skull muscles of Spinosaurus. Its skull had a narrow snout filled with straight conical teeth that lacked serrations. There were six or seven teeth on each side of the very front of the upper jaw, in the premaxillae, and another twelve in both maxillae behind ...

    Baryonychinae is an extinct clade or subfamily of spinosaurids from the Early Cretaceous of Europe and West Africa.The clade was named by Charig & Milner in 1986 and defined by Sereno et al. in 1998 and Holtz et al. in 2004 as all taxa more closely related to Baryonyx walkeri than to Spinosaurus aegyptiacus.
