Charles Jean Julien Depéret (25 June 1854 – 18 May 1929)[1] was a French geologist and paleontologist.
[4] In 1892 he introduced the Burdigalian Stage (Lower Miocene) based on stratigraphic units found near Bordeaux and in the Rhône Valley.
[6] Along with Edward Drinker Cope, who appears not to have written on this topic,[7] his name is associated with the so-called "Cope-Depéret rule", a law which asserts that in population lineages, body size tends to increase over evolutionary time.
[8] In his book Les transformations du monde animal, he denied that any instance of reduction in body size in evolution had been documented.
[18] The following list contains a few of his other noted writings: Deperetella, an extinct perissodactyl, is named after Depéret.
