Utuntu dushimishije
Kelmayisaurus is known from only a partial skull, including a left dentary (lower jaw bone) and part of the upper jaw.1
Its name means 'Karamay lizard' after the city of Karamay in Xinjiang, China, which is famous for petroleum.1
For a long time, scientists thought Kelmayisaurus might be a nomen dubium (a doubtful name) because its fossils were so few. But a 2011 study confirmed it is a valid genus.12
Kelmayisaurus is one of only two carcharodontosaurid dinosaurs known from Asia, showing that these giant predators lived all over the world.2
The only known fossil of Kelmayisaurus was found in the Lianmuqin Formation, which dates to between 140 and 100 million years ago.1
A supposed second species called 'K. gigantus' was mentioned in a book, but it was a mistake and actually refers to a different dinosaur called Klamelisaurus.1

Gusenya ibinyoma
Ibivugwa: Some people think Kelmayisaurus was a giant 21-meter-long dinosaur.
