About this unit

Dinosaurs are a favourite with almost every class. This unit uses that excitement to teach the science behind them: what fossils are, how they form in layers of rock over millions of years, and what they tell us about living things that are now extinct.

The KS1 story is pure wonder, with a friendly herbivore and nothing scary. The KS2 story is a careful discovery on the coast, modelled on how real fossil finds are made, studied and given to museums.

KS1 (Reception to Year 2): The Glowing Fossil

Learning objective

Describe what a fossil is and name some dinosaurs that ate plants or meat.

Talk questions

  1. What clues helped our hero find Fern’s herd?
  2. How do we know about dinosaurs if no one has ever seen one?

Writing task

Draw Fern and her herd. Write one sentence: 'Fern is a herbivore, so she eats ___.'

Suggested story settings: Genre: Adventure · Length: 2 chapters · Time: 10–15 minutes

The story brief

What the class story is asked to do. “Our hero” is the character your class chooses.

A fossil hunt for young readers. On the beach at Fossil Bay, our hero finds a stone with a curly shell pattern that glows when they hold it. It opens a window into the time of the dinosaurs, and our hero steps through to meet a young herbivore called Fern, who has lost her herd. They follow giant footprints across a fern-covered valley until they find Fern’s family, munching leaves by a lake. Wonder and discovery, nothing scary: the only carnivore they see is far away and fast asleep. End back on the beach with the fossil, now just a stone again, in our hero’s pocket.

Sample opening · KS1

A sample written for this page to show the brief in action. It is not the story Litsee writes for your class.

The beach at Fossil Bay was full of stones. Grey stones, brown stones, round stones and flat stones.

But one stone was different. It had a curly pattern on it, like a snail shell, and when our hero picked it up, it began to glow.

“A fossil!” our hero whispered.

The glow grew brighter and brighter, and then, pop, a round window opened in the air. Through it, our hero could see tall ferns, a sparkling lake and a little green dinosaur with a long neck, looking lost.

Our hero stepped through the window. “Hello,” they said softly. “Are you all right?”

“I’m Fern,” said the dinosaur. “I can’t find my herd.”

Model text (WAGOLL)

Fern is a herbivore, so she eats leaves and ferns.

She has a long neck to reach the tallest trees.

Her herd munches all day by the sparkling lake.

The story brief

What the class story is asked to do. “Our hero” is the character your class chooses.

A fossil adventure for older primary readers. Our hero joins a young palaeontologist on a fossil-hunting walk along the cliffs at Fossil Bay after a storm has washed away part of the cliff. They find the edge of a large fossil in the rock. Through careful work, notes and a little imagination, the story shows how fossils form when living things are trapped in layers of rock over millions of years, and what fossils tell us about creatures that are now extinct. Weave in accurate facts and the real history of fossil hunting on the coast. End with the fossil safely in a museum and our hero’s name on the label as the finder.

Sample opening · KS2

A sample written for this page to show the brief in action. It is not the story Litsee writes for your class.

The storm had blown itself out overnight, and in the morning the beach at Fossil Bay looked different. A slice of the cliff had slumped onto the sand, leaving a fresh grey face of rock.

“After a storm is the best time to look,” said Priya, crouching beside the fallen clay. She was a palaeontologist at the local museum, and she had a rucksack full of brushes, notebooks and bubble wrap. “The sea does the digging for us.”

Our hero walked slowly along the bottom of the cliff, keeping well back from the rock face as Priya had asked. Then something caught their eye: a row of dark, curved shapes in the stone, each one the size of a hand, like the knuckles of an enormous fist.

“Priya,” they called. “I think you should see this.”

Priya looked for a long time without saying anything. Then she took out her notebook. “Those are vertebrae,” she said quietly. “Part of a backbone. Something big lived here, a very long time ago.”

Model text (WAGOLL)

A model answer to the writing task, pitched at Year 5, written for this page. Read it with the class and find where it meets each success criterion.

How Does a Fossil Form?

A fossil is the remains or the trace of a living thing, kept in rock for millions of years. Most fossils form in four steps.

First, an animal or plant dies and sinks to the bottom of a sea or lake. The soft parts rot away, leaving only the hard parts, such as bones, teeth or shells.

Next, layers of mud and sand settle on top. Over a very long time, more layers build up, and their weight presses the lower layers into rock.

Then, water seeping through the rock slowly replaces the bones with minerals. As a result, the bones turn into stone but keep their shape.

Finally, the rock is lifted and worn away by wind, rain or the sea, until the fossil appears at the surface, where a palaeontologist might find it.

Fossils matter because they show us living things that are now extinct, and how life on Earth has changed.

What makes it good

  • First, an animal or plant dies Time words put the steps in order.
  • As a result, the bones turn into stone Shows cause and effect.
  • Fossils matter because Ends by explaining why the topic matters.

A week of lessons

  1. Lesson 1

    Hook

    • Show a photograph of a real ichthyosaur fossil in a museum. Ask: how did an animal turn into stone? What would have to happen?
    • Talk: How did the palaeontologist work out what the fossil was?
  2. Lesson 2

    Plan

    • Talk: Why do you think it matters to report a fossil find to a museum?
    • Words: fossil, extinct, palaeontologist, herbivore, carnivore.
  3. Lesson 3

    Draft

    • Write: Write an explanation of how a fossil forms, step by step, using time words and the words cause and effect, with a labelled diagram.
  4. Lesson 4

    • Grammar focus. Conjunctions to join clauses: “Fossils matter because they show us living things that are now extinct, and how life on Earth has changed.”
  5. Lesson 5

    Publish

    • Set up a class fossil museum, with each explanation displayed beside its diagram as the label.
The printed plan adds the planning frame and the full steps for each lesson.

Support, core and stretch sheets

Support

Explain how a fossil forms in four numbered steps, each starting with a time word.

Core

Write an explanation of how a fossil forms, step by step, using time words and the words cause and effect, with a labelled diagram.

Stretch

Add a paragraph explaining what fossils tell us about extinct animals, and a glossary of three words.

Vocabulary mat

One A4 page for every table: the word bank with its meanings, sentence stems, useful words and grammar words.

Teaching notes

Make fossils in class with modelling clay and shells, or a salt dough “cast”. Children who have pressed a shell into clay understand how a print is left behind, which is the first step in how fossils form.

Show the layers of rock with a stack of coloured paper or a jar of sand and soil. Older layers are lower down, which is why a palaeontologist can tell roughly how old a fossil is.

Talk about the real history of fossil hunting on the English coast, such as the discoveries of Mary Anning in Lyme Regis two hundred years ago, and how she worked out what the creatures were from careful observation.

Questions parents and teachers ask

Is the dinosaur story gentle enough for Reception?

No. The KS1 story is about helping a young herbivore find her herd, and the only meat-eater is far away and asleep. The KS2 story is a careful fossil discovery.

Which year groups is the dinosaurs unit for?

Reception to Year 6. It links to rocks and fossils in Year 3 science and to evolution and inheritance in Year 6.

Is there a dinosaurs word bank?

Yes. The dinosaurs and fossils word bank has the topic words with child-friendly meanings, more nouns, verbs and adjectives, and a printable word mat.
