Cevdet Mehmet Kösemen (born 18 May 1984), also known by his former pen name Nemo Ramjet, is a Turkish researcher, artist, and author. Kosemen is known for his artwork, depicting living and extinct animals as well as surrealist scenes, and his writings on paleoart, speculative evolution, and history and culture in Turkey. Together with Australian paleoartist John Conway and British paleontologist Darren Naish, Kösemen co-authored All Yesterdays, a 2012 book exploring speculative ideas in paleoart, and Cryptozoologicon, a book applying speculative evolution ideas to cryptids, both of which were widely covered in international media. Among Kösemen's most known personal speculative evolution projects are the book All Tomorrows (2006) and the ongoing project Snaiad. Source: Wikipedia (en)
