Carcharodon hastalis is an extinct species of mackerel shark that lived between thirty and one million years ago during the late Oligocene to the Early Pleistocene epochs.

Its teeth can reach lengths up to 3.5 in (7.5 cm) and are found worldwide. [3] It is believed to be an ancestor to the modern day great white shark, an argument supported by the transitional species Carcharodon hubbelli , [4] [5]

Carcharodon hastalis teeth can grow up to 8.9 cm (3.5 in) in length, suggesting a very large shark. Its body was probably very similar to that of modern great whites. It is also believed to have a cosmopolitan distribution, with C. hastalis teeth being found worldwide. [6] The maximum adult length is estimated between 5 and 7 m (16 and 23 ft). [7] [8] Smaller individuals were about 2.6–4.5 metres (8.5–14.8 ft) long. [9]
