One of our Education Officers can come into school to provide a Fossil and Dinosaur session.

We have a number of real fossils and real dinosaur fossils to show and handle, including megalodon tooth, trilobites, ichthyosaur vertebra, triceratops teeth and Spinosaurus teeth.

Please contact the team education@jerseyheritage.org to book.

Dinosaurs went extinct 65 million years ago. There were many reason for the extinction of dinosaurs such as an asteroid, volcanic eruptions.

The Triassic Period (252-201 million years ago) began after Earth's worst-ever extinction event devastated life. The Permian-Triassic extinction event, also known as the Great Dying, took place roughly 252 million years ago and was one of the most significant events in the history of our planet.

The Jurassic period was the golden age for dinosaurs. It is also called the golden age of reptiles, as it witnessed the emergence of a huge diversity of reptiles. This era is divided into three periods - Triassic, Jurassic and Cretaceous. In the Jurassic period, giant reptiles like dinosaurs and toothed birds like Archaeopteryx dominated Earth.

Even though dinosaurs lived millions of years ago, we know about them thanks to fossils. Watch our animation to find out how fossils form and why dinosaur fossils are rare compared to fossils of marine animals.

Fossils are formed in many different ways, but most are formed when a living organism such as a plant or an animal dies and is quickly buried by a certain rock  (sedimentary) such as mud, sand or volcanic ash.

Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

Back then Earth was a lot warmer than it is today and there was little or no ice at the North Pole or South Pole. Sea levels fluctuated but were in the most part high. In fact, at times sea levels were 170 metres higher than today. Shallow seas formed, dividing some continents.

There is evidence that shows that an asteroid impact was the main culprit. Volcanic eruptions that caused large climate change may also have been a cause, together with more gradual changes to Earth's climate that happened over millions of years. There was more than one time they went extinct. Each period, (Triassic, Jurassic, Cretaceous) were all extinction periods
