吃：肉肉食恐龍侏羅紀中期

Cruxicheiros was a big meat-eating dinosaur that lived about 170 million years ago in what is now England. It was a fierce hunter that walked on two legs and had sharp teeth and claws. Its bones were found in a quarry in Warwickshire, and scientists think it was a close relative of the famous Megalosaurus.5 1

酷東西

趣味知識

Cruxicheiros was named in 2010, making it a relatively new dinosaur discovery.5

Its name means 'cross hand' in Latin and Greek, after the Cross Hands Quarry where its bones were found.1

The dinosaur's bones were discovered in the 1960s but were not identified as a new species until decades later.1

Cruxicheiros lived during the Middle Jurassic period, about 168 to 165 million years ago.5

The fossils include parts of the leg bones, vertebrae, and pelvis, but the skeleton is incomplete.1 2

Scientists are not sure exactly where Cruxicheiros fits in the dinosaur family tree, but it was a type of tetanuran theropod.2
