吃：肉迅猛龍類白堊紀早期

Nuthetes was a small, meat-eating dinosaur that lived about 143 million years ago. It had sharp, serrated teeth like a steak knife, perfect for slicing through flesh. Scientists think it might have been one of the earliest dromaeosaurids, the group that includes Velociraptor.1

趣味知識

Nuthetes was first thought to be a lizard or a crocodile, but later scientists realized it was a dinosaur.1

Its name comes from Greek and means 'one who admonishes' or 'a monitor', because its teeth look like those of a modern monitor lizard.1

Nuthetes is known only from teeth and jaw fragments, so scientists are not sure exactly what it looked like.1

If Nuthetes was a dromaeosaurid, it would be one of the oldest dromaeosaurids ever found.1

Some scientists think Nuthetes might be a tyrannosauroid instead of a dromaeosaurid, because its teeth look similar to those of Proceratosaurus.1

The first Nuthetes fossil was found by Charles Willcox, an amateur fossil hunter, in a quarry near Swanage, England.1

Nuthetes was about the size of a modern Bengal monitor lizard, which is around 1.5 to 2 meters long.1
