Megalodon size estimates vary depending on the method used, with maximum total length estimates ranging from 14.2–20.3 meters (47–67 ft). [ 35 ] [ 40 ] [ 25 ] A 2015 study estimated the modal total body length at 10.5 meters (34 ft), calculated from 544 megalodon teeth, found throughout geological time and geography, including juveniles and ...
The largest shark in the fossil record is the megalodon (Otodus megalodon), a colossal Neogene lamniform. The range of estimates of the maximum length for megalodon are from 17 to 20.3 m (56 to 67 ft), with a mass ranging from 65 to 114 short tons (59 to 103 t). [44] [45] [46] It is also regarded as the largest macro-predatory fish ever.
While human population records in orbit developed from 1 in 1961, 2 in 1962, 4–7 in 1969, 7–11 in 1984 and 13 in 1995, [44] to 14 in 2021, 17 in 2023 [45] and 19 in 2024, [46] developing into a continues population of no less than 10 people on two space stations since 5 June 2022 (as of 2024). [47]
