O. Obliquus is an extinct mackerel shark (family Lamnidae) that is believed to have grown to about 9 m in length. The species lived during Paleocene–Eocene times, about 60 to 37.5 million years ago. O. obliquus likely preyed upon marine mammals, large bony fish, and other sharks.

Thank you to Dr Mikael Siversson, Paleontology Curator, Western Australian Museum, for identifying the tooth.
