Dinosaurs – The Triassic Period

This term 2KM and 2KJ are learning about dinosaurs.

Last week we enjoyed learning about the Triassic Period. It is the first period of the Mesozoic Era, which was the era of the dinosaurs. The timeline below shows all of the stages of the Mesozoic Era.

Dinosaur timeline


We learnt some interesting facts about the Triassic Period, including:

* All the continents were joined together as one huge continent, it was known as Pangaea.

* There were no dinosaurs at the start of the Triassic period, but there were many amphibians and some reptiles.

* The Triassic dinosaurs were much smaller than the dinosaurs of the later periods.

* The climate in the Triassic period was hot and dry, causing desert like conditions.

* The Coelophysis is probably the most well known Triassic dinosaur. They were small and fast and hunted in packs.

* In the late Triassic Period, the first mammals appeared. They were tiny, about the size of mice, and probably nocturnal.

* There was a mass extinction at the end of the Triassic Period and about 35% of animal species died out.


We created a poster to show profiles of some of the Triassic dinosaurs…



We have enjoyed doing research about the Triassic Period, and the Enchanted Learning and Dinosaur Facts websites have some interesting information. Why not check them out yourself?

  1. Dear 2KM and 2KJ,

    Thank you for sharing those facts about the Triassic period. I only knew 2 of the facts – about Pangaea, and the climate of the Triassic period. I find it very interesting that the first mammals were probably nocturnal: I wonder if it was to hide from predators?

    After having a look around Dinosaur Facts (great sight! I’ll have to save it to share with my class!), I think the Coelophysis is my favourite. An interesting dinosaur – and I love that the first fossil sent into space was a Coelophysis fossil!

    Keep up the wonderful work,
    Stef Galvin

    • @ Stef,

      Great comment!

      Do you know the Coelophysis has rozer shap claws?

      That is a good reasen why :mrgreen:

      From your pal,
      Molly (2KJ) 😆

      • @ Molly,

        Thank you!

        I didn’t know that the Coelophysis had razor sharp claws – thank you for sharing that fact with me!

        All the best,

  2. Hi 2KM and 2KJ,

    Great post, Miss Jordan.

    I do know a bit about the Triassic Period. Do you?

    My favourite dinosaur from the Triassic Period is the, Pantydraco.

    I have a fact about it too, the Pantydraco is known from only a partial skeleton discovery.

    I made this dinosaur post up on Sqworl and I thought you might want to look at it. http://sqworl.com/hg22ib

    Great post again!


    • Dear Jordi,

      Thank you for leaving a comment on this post, your comment is very quality and interesting.

      No I do not know about the Triassic Period, but I know that Miss Jordan and Mrs Morris will teach us more about it because they are both very good teachers.

      I love your post it is great. 😆

      I can say it is a good post


      • @ Jordi and Kayla,

        Thankyou for your comments, they are great quality ones. 😆

        I love learning about dinosaurs.

        Keep up the good blogging girls.

        Your Friend,

          • @ jordi,

            thankyou for the reply too. I think you are a great bloger too. 😆

            What is your favourite period:?:

            best Wishes,

      • Hi Kayla, 😛

        Thanks for the reply. You’re a great blogger!

        Yes, Mrs Morris and Miss Jordan are great teachers and I’m sure they will teach us more.


  3. Hi 2KM and 2KJ,

    The study of dinosaurs was always a favourite for my classes. Over the years we’ve made paper mache dinosaurs, collage dinosaurs and painted pictures of dinosaurs.

    One year we even held a dinosaur fair in our room and invited all of the school to visit. The highlight was the paper mache dinosaur. We used it as a pinata. It had sweets and small plastic dinosaurs inside.

    One thing I have of interest in my rock collection is a dinosaur coprolite (fossilised dung). It came from a herbivorous dinosaur but I’m not sure which dinosaur or exactly what period it came from.

    Here is a link to a photo of it. The squares in the photo are 1cm wide…


    One interesting thing happened just before seeing your post, I was checking emails and found a story from Australian Geographic. It was about the discovery of new dinosaur footprints in Victoria. Here is a link to the story…


    There is a fun park in Merimbula, NSW. It’s called Magic Mountain. One of their attractions is called Triassic Park. While the models of animals in there aren’t all Triassic or to scale, local children can have some idea about the size of dinosaurs.

    There is a wonderful DVD collection from BBC looking at the beginning to the end of the dinosaurs. It’s called, “Walking With Dinosaurs”. You may have heard about this series.

    I hope you have great fun with the study of dinosaurs.

    • Dear Ross Mannell,

      Thank you for leaving a comment on our blog. In our class we have not made paper dinosaurs.

      We do know about walking with dinosaurs because we have watched part one. It looks scary.

      Your pal,

  4. @ 2KM and 2KJ,

    I love the post!
    I love learning about dinosaurs! 😆

    My favourite dinosaur is the T-Rex. I like the T-Rex because it’s big. I also like the Coelophysis because it’s colourful.

    I didn’t really know anything about the triasic period, but now I know a couple of things and I’ll tell you one.

    I know that all the continents joined together to make a big continent called pangaea.

    I’m glad that I wasn’t alive when dinosaurs were alive, because then I probably would have died from all the meat eating dinosaurs. 😥

    I love the post again!

    Best Wishes,

    • Dear Alana,

      Your comment is great!
      I love this post too!
      I love leaning about dinosaurs too.
      I cannot believe that the world was all together.

      Your friend,

      • @ Eb,

        Thankyou for the reply. Your a great bloger.

        I didn’t believe that the world was stuck together, too. 😆

        Best Wishes,

  5. @ 2KM and 2KJ,

    Great and awesome post!
    My favourite dinosaurs from the Triassic Period are, the Postosuchus, the Brontosaurus and the Eoraptor. What are your favourite dinosaurs from the Triassic Period?


  6. Dear 2KM and 2KJ,

    Great post Miss Jordan I really like it.

    This is a fact about the Triassic Period. During the Triassic period (about 248 to 199 million years ago), most of Earth’s land continued to stick together in one big supercontinent. Because the middle of Pangaea was so far from the oceans, it was very dry there, like a desert. The whole world was generally pretty warm all through the Triassic period. Even at the North and South poles, there wasn’t any ice.

    My favourite dinosaur is the Fabrosaurus, Saltopus, Coelophysis and the Procmpsognathus I think those dinosaurs are my favourite.

    Hope we learn more facts about dinosaurs.

    What is your favourite dinosaur?

    Bye for now,
    Millie 😆

    • Dear Millie,

      What a great comment.

      Thanks for sharing your AWESOME facts.

      I never knew that the North Pole and the South Pole had no ice when the dinosaurs were around.

      My favourite dinosaur from the triassic period is the Saltopus and my actual favourite dinosaur is the Brachiosaurs. It comes from the Jurassic period.

      Thanks for the great facts again.

      Talk to you soon,
      Ava 😛

  7. Dear 2KJ and 2KM,

    I love Dinosaurs!!
    I love the T-rex because I like there teeth.

    I am sorry but I don’t really know some facts about Dinosaurs but I bet Miss Jordan and Mrs Morris teches us some.

    I sometimes like the green Dinosaur but I don’t know what its called at least I know the colour.

    Which Dinosaur do you like ❓
    Do you like T-rex’s?

    I really love this blog I upresheate Miss Jordan and Mrs Morris thinking of Dinosaurs.

    Georgia.♥ 😛

  8. Dear 2KM and 2KJ, 😆

    Great post Miss Jordan.

    Is the T-Rex in the Triassic period:?: If it is that’s my favourite dinosaur in the Triassic period. :mrgreen:

    One of the facts I know is if a big dinosaur is chases a little dinosaur, if the little dinosaur goes on very soft mud the big dinosaur will sink.

    I love the post again.

      Warm wishes,

  14. Dear 2KJ and 2KM,

    It is so exciting that you are learning about dinosaurs at school! When I was a lot younger (probably in grade 2!), there was a dinosaur park that you could visit near Ballarat. It didn’t have real dinosaurs, but it did have life size models of dinosaurs spread throughout the bush. You could walk around the park and be surprised or scared by the next dinosaur that you would see! Unfortunately the dinosaur park is not there anymore.

    My favourite dinosaur from the Triassic Period is Plateosaurus because it was one of the largest.

    Looking forward to reading some more dinosaur blogs!
    Arran (Charlotte’s dad).

    • Dear Dad,

      I can rember when i was 3 or 4 you fond it online a so we went their and when we got their a sine said it was gone i was very sad but we fond another place to go to!
