Comment: Do not immediately resubmit after draftication. The refs are broken (I would've fixed them, but I don't have access to the original sources) Also poorly written with a uncertain tone. '''[[User:CanonNi]]''' (talk • contribs) 06:29, 8 October 2024 (UTC)

Isurus desori or "Desori shark", or "Desori mako shark" is extinct species of Mako shark, what lived in Oligocene and Middle Miocene, in 34 and 11 milions years ago. He measured 4.2 meters (14 ft) long.
Diet
editThe Isurus desori hunted squids, fish and marine mammals. The fossil of I. desori was discovery in Chesapeake Bay region.[1]
Taxonomy
editThe I. desori belongs to the family Lamnidae. It is classified in the genus Isurus, and it is believed that it was the ancestor of the present-day mako shark (Isurus oxyrinchus). It is believed to be related to C. hastalis, and C. xiphodon, as well as the Mako shark (Isurus oxyrinchus).[2] Scientists believe that I. desori belongs to the subfamily Isuridae, where it evolved into the only two contemporary species, I. paucus and I. oxyrinchus, the only surviving species of the genus Isurus.[3] It was once believed that I. desori belonged to the genus Oxyrhina, which is now considered a probably invalid or doubtful genus.
