How Palaeontology Works
Digging, preparing, dating and reconstructing a fossil
Palaeontology is a working science with methods, disputes and a history, and this unit is about the process rather than its conclusions.
It covers fieldwork and excavation, preparation in the laboratory, dating rocks, reconstructing an animal from partial remains, and how the discipline itself developed.
This unit breaks down into 18 short steps and 107 questions, starting at difficulty 2 and building to 4. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

What this unit covers
- Fieldwork and Excavation
- Rebuilding an Animal
- The History of the Science
- Preparation and the Lab
- Dating the Rocks
Where this fits
Follows Fossils and Fossil Hunting.
Where people slip
Most reconstructions involve substantial inference. A species known from a partial skull still gets drawn as a whole animal, and the parts nobody has found are the parts most likely to be revised.
How the unit is structured
How Palaeontology Works runs as 18 short steps that unlock in order. 13 are practice rounds and 5 are challenge rounds that pull together everything before them. Questions start at difficulty 2 and climb to 4 as you progress.
Challenge rounds
Example questions
30 real questions from this unit, with the answer and the reason behind it, grouped by what they practise. There are 107 in the unit altogether.
Dating the Rocks
- Put in orderLevel 2
1. Put these dating steps in order.
Answer: Record which layer the fossil came from -> Find volcanic ash layers nearby -> Date those layers radiometrically -> Bracket the fossil's age between them
Record the layer, find datable ash, date it, then bracket the fossil's age.
- True or falseLevel 2
2. Radiocarbon dating cannot be used on dinosaur fossils because they are far too old.
Answer: True
True. Carbon-14 is useless beyond about fifty thousand years.

- guess
- discount
Every measurement carries an uncertainty.
- Multiple choiceLevel 3
5. What does relative dating tell you?
- Which layers are older or youngercorrect
- The exact age in years
- The animal's weight
- The colour of the rock
It tells you the order of events, not the number of years.
- Type the answerLevel 3
6. What principle says that in undisturbed layers, lower rock is older?
Answer: superposition
Superposition is the foundation of stratigraphy.
Fieldwork and Excavation

7. Which records are made during excavation? Pick all that apply.

- GPS coordinatescorrect
- Notes on the rock layercorrect
- The finder's shoe size
Photographs, maps, GPS coordinates and notes on the rock layer are all essential.

8. Many countries require a permit before fossils can be collected.
Answer: True
True. Fossils are often protected as scientific or national heritage.
- Fact or fibLevel 3
9. Screen washing sediment can recover tiny teeth and bones easily missed by eye.
Answer: True
True. It is how many small mammal and lizard fossils are found.
- Fill the blankLevel 3
10. Bones are protected for transport inside a ____ jacket.
- plastercorrect
- paper
- plastic bag
- wooden
Plaster and burlap form a protective shell.
- Multiple choiceLevel 3
11. Why do teams map exactly where each bone lies before removing it?
- Because bone positions are evidence in themselvescorrect
- To make the dig look neat
- To count them for sale
- Because the law says so everywhere
The position and orientation of bones is evidence that cannot be recovered later.
- Type the answerLevel 3
12. What is the word for searching the ground surface for signs of fossils?
Answer: prospecting
Prospecting is walking and scanning for weathered-out bone.
Preparation and the Lab
- Fill the blankLevel 2
13. A specialist who removes rock from fossils is called a ____.
- preparatorcorrect
- prospector
- professor
- printer
Preparators are highly skilled technicians.
- Multiple choiceLevel 2
14. What happens in a fossil preparation lab?
- Rock is removed and fossils are stabilisedcorrect
- Fossils are painted for display only
- Fossils are melted
- Fossils are sold
Preparators carefully remove rock from bone and stabilise fragile material.
- True or falseLevel 2
15. Glue and consolidants used on fossils are chosen to be reversible where possible.
Answer: True
True. Future researchers may need to undo the treatment.
- Choose all that applyLevel 3
16. Which tasks belong to a preparator? Pick all that apply.
- Removing surrounding rockcorrect
- Stabilising fragile bonecorrect
- Reassembling broken piecescorrect
- Naming the species
Removing matrix, stabilising bone, reassembling fragments and documenting the work are all their responsibility.
- Fact or fibLevel 3
17. Some fossils are prepared under a microscope with tools as fine as needles.
Answer: True
True, especially for tiny or delicate specimens.
- Type the answerLevel 3
18. What small air-powered tool chips rock away from bone?
Answer: air scribe
An air scribe works like a miniature jackhammer.
Rebuilding an Animal
- Fact or fibLevel 2
19. Good palaeoart should be able to point to evidence for its choices.
Answer: True
True. Speculation is fine, but it should be identified as such.
- Fill the blankLevel 3
20. Comparing a fossil with living relatives such as birds and crocodiles is called ____ bracketing.
- phylogeneticcorrect
- geological
- chemical
- magnetic
Phylogenetic bracketing constrains what soft tissues an extinct animal likely had.
- Multiple choiceLevel 3
21. How do scientists work out what a dinosaur looked like alive?
- From the skeleton, muscle scars and living relatives
- By guessing freely
- From ancient paintings
- From written descriptions
They combine skeleton anatomy, muscle scars and comparisons with living relatives.
- Put in orderLevel 3
22. Put the steps of reconstructing a dinosaur in order.
Answer: Assemble and check the skeleton -> Reconstruct muscles from scars -> Add skin and other soft tissue -> Choose colour and behaviour carefully
Assemble the skeleton, add muscles, add soft tissue, then colour and behaviour.
- True or falseLevel 3
23. Missing bones are often reconstructed using closely related species as a guide.
Answer: True
True, and honest reconstructions make clear which parts are inferred.

24. Which evidence constrains a soft-tissue reconstruction? Pick all that apply.
- Bone surface texturecorrect
- Muscle attachment scarscorrect
- Phylogenetic bracketingcorrect
- Artistic preference

Answer: True
True. She could not join the scientific societies that used her discoveries.
- Sort into groupsLevel 4
30. Sort each activity by the stage of research it belongs to.
Answer: Prospecting an outcrop = Fieldwork; Jacketing a bone = Fieldwork; Removing matrix = Laboratory; Peer review = Publication
A study runs from field to publication.
Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
