酷東西

趣味知識

Oryctodromeus means 'digging runner' because it could both dig burrows and run fast on two legs.1

Its burrow was about 2 meters (6.6 feet) long and 70 centimeters (2.3 feet) wide, with two turns.1

The adult Oryctodromeus was about 2.1 meters (6.9 feet) long and weighed between 22 and 32 kilograms (50 to 70 pounds).1

Two baby Oryctodromeus were found with the adult, showing that parents cared for their young in the burrow.1

Its strong shoulders and arms helped it dig, but it was not as specialized for digging as a mole or wombat.1

Oryctodromeus was named the state dinosaur of Idaho in 2023.1

The burrow was filled with sand and turned into sandstone, which preserved the bones inside.1
