Datos curiosos
The only known fossil of Archaeornithoides is a tiny skull and jaw fragment, just 27 millimetres long.1
The fossil has bite marks on it, and scientists think a weasel-sized mammal called Deltatheridium may have bitten off the dinosaur's head.1
This dinosaur lived about 83 to 72 million years ago, during the Late Cretaceous period.2
Its name means 'shaped like an ancient bird' because it had many bird-like features in its skull.1
Some scientists think Archaeornithoides might be a baby of another troodontid dinosaur, but others believe it is a distinct species.1
The fossil was found in 1965 by a Polish-Mongolian expedition, but it wasn't named until 1992.1
As preguntas máis frecuentes sobre Archaeornithoides
?How big was Archaeornithoides?
About 50 to 60 centimetres long, based on the only known fossil, which was a juvenile. Adult size is not known for sure.1
?What did Archaeornithoides eat?
It was a carnivore, meaning it ate meat. Its small, smooth teeth were good for catching tiny prey.31
?Did Archaeornithoides have feathers?
No fossil feathers have been found with Archaeornithoides, but because it was a close relative of birds and troodontids, many scientists think it probably had feathers.1
?Is Archaeornithoides a bird?
No, it is a non-avian dinosaur, not a bird. But its skull had many bird-like features, which is why its name means 'shaped like an ancient bird'.1
