Khudiakovia

Say it: KOO-dee-ah-KOH-vee-ah
Ate: MeatIchthyosaursEarly Jurassic to Early CretaceousNot technically a dinosaur

Khudiakovia was a fast-swimming marine reptile that lived in the oceans during the Jurassic and Early Cretaceous periods. It had a huge eye, a long snout, and a body shaped like a dolphin. It was not a dinosaur, but a type of ichthyosaur.1

Fun fact: this sea reptile swam while dinosaurs walked on land. Everyone calls them dinos, but they were a different branch of reptiles.

Fun facts

1

Khudiakovia had an enormous eye, which helped it see in the dark ocean depths. The eye socket was very large compared to its skull.1

2

Its bones were made of hydroxyapatite, the same mineral that makes your teeth and bones hard.1

3

Khudiakovia gave birth to live young, just like whales and dolphins do today. It did not lay eggs.1

4

This ichthyosaur lived from about 201 million years ago to about 132 million years ago, a span of nearly 70 million years.1

5

Khudiakovia was a fast swimmer that moved through the water like a fish. Its body was built for speed.1

Most asked questions about Khudiakovia

?How big was Khudiakovia?

Nobody knows for sure because no complete skeleton has been found. It was a medium-sized ichthyosaur, and related species like Ophthalmosaurus were about 4 metres (13 feet) long.25

?What did Khudiakovia eat?

It was a carnivore that ate fish and squid. Its conical teeth were good for catching slippery prey.34

?Could Khudiakovia swim fast?

Yes, it was a fast swimmer. Its body was streamlined like a dolphin’s, and it used its tail fluke for powerful strokes.3

?Did Khudiakovia have feathers?

No, it was a marine reptile, not a dinosaur. It had smooth skin and flippers, not feathers.3

?When did Khudiakovia live?

It lived during the Callovian age of the Jurassic Period, about 165 to 161 million years ago.5

?Was Khudiakovia a dinosaur?

No, it was an ichthyosaur, a type of marine reptile that lived in the sea. Ichthyosaurs are not dinosaurs.3
