Trierarchuncus
Trierarchuncus was a tiny, feathered dinosaur that lived right at the end of the age of dinosaurs. It had short arms with just one big claw on each hand, like a hook. It ran fast on its long legs and probably ate insects and small animals.1

Makambo ya kosepelisa
Trierarchuncus is the youngest known alvarezsaurid, meaning it lived just before the big extinction 66 million years ago.1
Its name means 'captain hook' because its hand had only one big claw, like a pirate's hook.1
Scientists think Trierarchuncus was covered in feathers, like many of its relatives.1
It lived alongside famous dinosaurs like Tyrannosaurus and Triceratops in the Hell Creek area.1
The first fossils were found in Montana in 1980, but it wasn't officially named until 2020.1
Trierarchuncus had a bird-like head and long legs, so it could probably run quickly.1

It probably ate insects and small animals. Scientists think it used its single big claw to tear apart logs and search for bugs, like an anteater.12

It lived right at the end of the age of dinosaurs, about 66 million years ago. It went extinct in the big mass extinction that killed most dinosaurs.1
