Dzharacursor

Dzharacursor was first thought to be a different dinosaur called Archaeornithomimus, but in 2025 scientists gave it its own name.1

Its name comes from the place where its bones were found, Dzharakuduk, and the Latin word for runner.1

One of its thigh bones might have medullary bone, a special tissue that female birds grow when they are about to lay eggs. This suggests Dzharacursor females became ready to have babies before they were fully grown.1

Dzharacursor lived alongside other dinosaurs like the big predator Ulughbegsaurus and the tyrannosaur Timurlengia.1

Scientists have found many bones of Dzharacursor, including parts of its skull, backbone, arms, and legs.1

Dzharacursor is one of the oldest ornithomimids known from Asia, living about 90 million years ago.2
