Aquilops may be tiny, but it has reshaped how we understand the migration of horned dinosaurs from Asia to North America. With its small skull, curved beak, and a peculiar bump on its nose, this little dinosaur proves that even the smallest creatures can make a big mark in history.

A small but priceless fossil
Aquilops americanus was described in 2014 based on a partial skull found in Montana, USA. Measuring just 8.4 cm, the fossil is a true paleontological gem. It was initially believed to belong to the Zephyrosaurus genus, but its unique facial structure led scientists to identify it as a new species among early ceratopsians.
Its discovery provided direct evidence of the migration of dinosaurs from Asia to North America, expanding our evolutionary map.
How big was Aquilops?
This miniature dinosaur was far from a giant:
| Feature | Aquilops |
|---|---|
| Total length | Approx. 60 cm |
| Estimated height | Less than 20 cm |
| Weight | 1.5 kg (about a chicken) |
| Continent | North America |
Compared to other early ceratopsians like Psittacosaurus from Asia (1.2 m), Aquilops was nearly half the size.

What did Aquilops eat?
Aquilops was a small herbivore. Its curved, parrot-like beak was ideal for cutting through leaves, soft stems, and perhaps low-growing shoots. It likely lived in forested areas, staying hidden while foraging.
Although its teeth haven’t been preserved, scientists have inferred its diet from its jaw structure.
What makes it special?
- A nasal bump resembling a tiny horn.
- A beak and skull that resemble an eagle’s—hence the name Aquilops (“eagle face”).
- The oldest known ceratopsian found in North America.
- It provides key insights into the early evolution of horned dinosaurs.
What was its environment like?
It lived during the Early Cretaceous, in a landscape of forests, rivers, and wet plains. It shared its habitat with other small herbivores and larger carnivores, which made hiding and agility essential for survival.
Frequently asked questions about Aquilops
What did it eat?
Soft vegetation: leaves, stems, shoots.
Was it dangerous?
No, it was a small herbivore with no notable defenses.
Is it the smallest dinosaur ever?
It’s one of the smallest known in North America, though some species like Microraptor were even smaller.
What makes it different from other ceratopsians?
Its small size, ancient age, and unique nasal bump.
The little traveler of big discoveries
Aquilops proves that size doesn’t matter when it comes to scientific impact. Its fossil has helped piece together the ceratopsian evolutionary puzzle and remains essential for understanding intercontinental migration.
