The sea was the predators' hunting field. Giant mosasaurs, sharks, sea crocodiles, cuttlefish and herrings with sable teeth hunted their prey at the bottom of the sea and in open bodies of water. Read more

At the bottom of the sea

The animals on the seabed had plenty to eat, but they also risked sinking deep into the seabed's soft mud and suffocate. The constant danger was a challenge that the animals met in many different ways. Read more

In the seabed

The seabed mud was a good and safe place to live. It was home to many different animals – including some that we have never seen! Read more

On land and in the air

The mighty dinosaurs lived on land, while the pterosaurs and the early birds would fly around in the air. No dinosaurs lived by Stevns Klint, as Stevns was covered by approx. 200 metres of sea. Read more

When Stevns was covered by the sea

65.5 million years ago, Stevns was covered by a deep sea.

By Stevns Klint, you can find fossils of the animals that lived during the Cretaceous Period 65 million years ago. Back then, Stevns, most of Denmark and Northern Europe were covered by a deep sea.

The Cretaceous Period was a lush age in Earth's history where the animals in the sea had plenty of food.

Many kinds of cuttlefish and fish lived in the area that is now Stevns. They included peaceful herbivores, ferocious predatory fish with sable teeth and sharks, and sometimes a sea crocodile would also swim by. The largest predator in the sea, however, was the sea lizard – the mosasaur. It could be up to 15 metres long and was related to monitor lizards.

On the seabed, there were sea urchins, mussels and brachiopods. Meanwhile, other animals would burrow into the seabed where they lived in complex tunnel systems.

In the air above the sea, pterosaurs and early birds would fly. The pterosaurs could have a wingspan the size of a small sports plane.

The dinosaurs only lived on land and therefore, none were found by Stevns Klint. The closest places where dinosaur skeletons have been found are Southern Sweden and Northern Germany where the coastline around the sea was found. The dinosaurs came in all sizes from 50 cm to 35 metres long.

However, life on dry land and at sea changed dramatically when an asteroid hit Earth.
