Pectinodon

Say it: pek-tin-oh-don
Name means: “comb tooth”1
Ate: A bit of everythingRaptorsLate Cretaceous

Pectinodon was a small, bird-like dinosaur that lived at the very end of the Age of Dinosaurs. It had sharp, comb-shaped teeth that helped it eat soft foods like insects and small animals. Scientists only know it from its teeth, but they think it was a fast, feathered hunter.1

Fun facts

1

Pectinodon is only known from teeth, not from bones or skeletons.1

2

Its teeth have comb-like serrations on the back edge, which is why it is named 'comb tooth'.1

3

The teeth are small, less than 1 cm tall, and are flattened from side to side.1

4

Pectinodon lived about 67 to 66 million years ago, right before the dinosaurs went extinct.1

5

It belonged to the troodontid family, which were smart, bird-like dinosaurs with big eyes and a sickle claw on each foot.1

6

Some scientists think Pectinodon might have been omnivorous, eating both plants and meat.1

Most asked questions about Pectinodon

?What did Pectinodon eat?

Pectinodon likely ate soft foods like insects, small vertebrates, or carrion. Some scientists think it might have been omnivorous, eating both plants and meat.13

?How big was Pectinodon?

Scientists don't know for sure because only its teeth have been found. The teeth are small, less than 1 cm tall, and its family Troodontidae were small, bird-like dinosaurs.1

?When did Pectinodon live?

Pectinodon lived about 67 to 66 million years ago, at the very end of the Late Cretaceous period, right before the dinosaurs went extinct.13

?Was Pectinodon a dinosaur?

Yes, Pectinodon was a small theropod dinosaur. It belonged to the troodontid family, which were bird-like feathered dinosaurs.13

?Did Pectinodon have feathers?

Scientists think so. While Pectinodon is only known from teeth, its family Troodontidae were small, bird-like feathered dinosaurs.1

?Why is it called Pectinodon?

The name means 'comb tooth' because its teeth have comb-like serrations on the back edge. The name comes from Latin and Greek words for 'comb' and 'tooth'.1

Discovery
Kenneth Carpenter named Pectinodon bakkeri in 1982 based on a single tooth from the Lance Formation in Wyoming. The species name honors paleontologist Robert Bakker.1
Still debated
Scientists debate whether Pectinodon is a valid genus or just a species of Troodon, and whether all the teeth from different formations belong to the same species.1
