Taxonomy
Megalosaurus crenatissimus was named by Depéret (1896) [original types FSL 92.289, 92.290, 92.306, 92.343 set aside as per ICZN Opinion 2269.]. Its type specimen is MNHN.MAJ 1, a mandible, and it is a 3D body fossil. Its type locality is Mevarana site 2, which is in a Maastrichtian fluvial-lacustrine sandstone in the Maevarano Formation of Madagascar.

It was recombined as Dryptosaurus crenatissimus by Depéret and Savornin (1928); it was considered a nomen dubium by Sampson et al. (1998); it was recombined as Majungasaurus crenatissimus by Lavocat (1955), Lapparent (1957), Steel (1970), Russell et al. (1976), Taquet (1977), Obata and Kanie (1977), Taquet (1984), Pant et al.
