Dinosaurs are extinct reptiles that lived on Earth during the Mesozoic era that occurred between 251–65 million years ago. Dinosaurs came in all shapes and sizes, and we know about them because dinosaur scientists, called paleontologists, study their fossils.

Dinosaurs and definitions

Dinosaurs lived on Earth during what is called the Mesozoic era (which is Greek for 'Middle Life') of the world’s history. Different dinosaurs lived in each of the different time periods.

Triassic : 251–200 million years ago

Jurassic : 200–145 million years ago

Cretaceous : 145–65 million years ago

Carnivore : an animal that eats other animals, a meat eater.

Herbivore : an animal that only eats plants.

Omnivore : an animal that eats both plants and meat.

Piscivore : a type of carnivore that eats only fish.

Ankylosaurus : A herbivorous, armoured dinosaur that lived during the late cretaceous period.

Apatosaurus (Brontosaurus): A herbivore, one of the biggest animals ever, and could grow up to 23 meters long. It lived during the Jurassic Period.

Stegosaurus : A herbivore that had large plates along its spine. It lived in the late Jurassic Period.

Spinosaurus : A carnivore or a piscivore, scientists aren't sure. It lived during the late Cretaceous period.

Triceratops : A herbivore with three horns on its head. It lived during the Cretaceous Period.

Tyrannosaurus rex (T-Rex): One of the most famous dinosaurs because of its huge size. It was a carnivorous dinosaur that lived during the late Cretaceous Period.

Velociraptor : A carnivore that lived during the late Cretaceous Period.

General websites

The websites listed here will help you find out more about the various types of dinosaurs, when they lived, what they ate, and why they became extinct.

Britannica School

Britannica School is part of the EPIC databases which is a collection of reliable databases covering lots of different topics. It’s put together especially for New Zealand school students and helps to answer questions like this.

  • Choose Primary to begin with and enter the search word 'dinosaur'.

  • Read the articles dinosaur (extinct reptile) to understand when and where dinosaurs lived, their behavior, and why they are not alive anymore.

  • If you scroll down the page of results, you will find links to many types of dinosaurs such as tyrannosaurus rex, brachiosaurus, diplodocus, and more.

  • You can always move up a reading level by going to Article Reading Level at the top of the page and selecting 2.

Tips: To get to the EPIC resources you will need a password from your school librarian first. Or you can chat with one of our AnyQuestions librarians between 1 and 6pm Monday to Friday and they will help you online. Some EPIC databases may also be available through your public library.

Fact Monster

Fact Monster is an online encyclopedia and homework site. It has lots of basic facts and is a good starting point for all sorts of questions. If you scroll down to the bottom of the site, you will see it’s run by Pearson Education, a publisher of educational books.

  • To find information on this website, enter the keyword 'dinosaurs' into the search at the top.

  • This will take you to the main Dinosaurs page which has heaps of links to more specific information like the classification of Dinosaurs and dinosaur discoveries made in recent years.

Tips: Some websites have advertisements (or ads) which ask us to buy something or tell us to ‘click here’. It’s best to ignore these ads and focus on the information we’re looking for.

New Zealand sites

Fossils found in New Zealand tell us that dinosaurs once lived in New Zealand. Explore the sites below to know more about their history in our country.

Te Ara: The Encyclopedia of New Zealand

Te Ara is an excellent starting point for all questions about New Zealand Aotearoa. If we scroll down to the bottom of the page we can see that the website belongs to the Ministry for Culture & Heritage, so the information is well-researched and reliable.

To find information about what fossils have been found in New Zealand, including dinosaur fossils:

  • From the homepage, select Earth, Sea and Sky

  • then choose Geology, and

  • next choose Fossils to find Age of the dinosaurs – Mesozoic to read which types of dinosaurs were found here.

Topic Explorer

Topic Explorer is an online tool from the National Library of New Zealand. It contains a wide range of quality resources for students in a range of formats, (eg articles, books, images, videos, primary sources, sets, websites) on a variety of topics. These resources have been selected from reliable national and international sources.

  • The topics are organised in alphabetical order, so all you need to do is look down the list until you find dinosaurs.

Tips: We like sites that are from government or other reputable organisations, like the National Library of New Zealand, because we can trust the information. You can sometimes tell these sites by their web address – they might have .govt or .edu in their address – or by looking at their About us or Contact pages.

Science Learning Hub

This website was put together by the University of Waikato and Curious Minds for school students. It contains a selection of articles, videos, and activities of science topics and concepts.

Tips: Websites that have .org or .net in the address can have good information, but you need to assess how reliable it is. Check the About us link on the website, if you can find one. That can tell you what the organisation’s mission and values are.
