Compare two dinosaurs with a few clear questions

Choose a pair for one clear reason

Ask the child to choose one familiar dinosaur and one they want to know more about. Alternatively, choose two profiles with an obvious shared question: did they eat similar things, or did they live during the same named period? Keep the activity focused on those two profiles so you can return to both descriptions.

Decide what you are comparing before gathering every available fact. “Which was bigger?” may be interesting, but it can quickly require careful comparisons of length, height, mass and estimates. For a first session, diet and period usually make a more manageable pair of headings.

If the selected creature is outside the dinosaur group, you can still compare it with another prehistoric animal. Name the activity accordingly. A prehistoric collection is broader than a collection containing only dinosaurs.

Ask the same four questions of both profiles

1. When? Find the named period or time range. Read the label rather than guessing from the animal’s appearance.
2. What did it eat? Look for the stated diet and any explanation of the evidence. Distinguish the profile’s wording from an idea you have inferred.
3. What feature can we describe? Choose a feature mentioned in the text. If you are only looking at an illustration, introduce it as “The picture shows…”
4. What do we still want to know? Keep one question open instead of filling every gap with a guess.

On paper, write each animal’s name and these four headings underneath it. Use a short phrase for each answer, then add where it came from. If a profile does not answer a question, “not found here” is a useful note. There is no need to invent an answer to complete the page.

A worked example: same period, different diets

The Natural History Museum’s directory places Tyrannosaurus and Triceratops in the Late Cretaceous. It identifies the former as carnivorous and the latter as herbivorous.

Those facts support a simple comparison sentence: “Both lived in the Late Cretaceous, but their diets differed.” Ask the child to point to the words that support each half. This gives the sentence a clear source instead of relying on which illustration looks fiercer.

A useful follow-up question is, “What evidence helps researchers work out diet?” Leave it as a question for another profile, museum resource or later conversation if you do not have a source in front of you. This example does not depend on both animals being available in an unlocked app pack.

Separate the picture from the supporting text

Illustrations make a creature easier to imagine, but an illustration is a reconstruction. A moving or tilting card does not turn every depicted color, sound or behavior into an established fact. Dinopedia’s product page encourages readers to compare era, fossil location and described features while recognizing uncertainty in reconstructions.

Try three spoken labels during the activity: “The profile says…”, “The picture shows…” and “We are wondering whether…”. They help keep different kinds of statements separate without interrupting the child’s interest with a lecture. A child can enjoy the picture and still ask how much of it researchers can support.

If two sources disagree, keep the exact point of disagreement. Check whether they discuss the same animal, measurement or discovery. Paleontology changes as evidence is studied; the app’s own listing notes that profiles can contain inaccuracies or become outdated.

End with one sentence and one question

A suggested short session has a clear finish: read the two profiles, write answers under the headings you can complete, say one supported comparison and choose one question to keep. You can stop there. Exploring every era or completing a collection need not become the family’s assignment.

If you use a trivia round afterward, discuss one answer rather than treating a score as a measure of understanding. Ask what in the earlier profiles helped, or what needs another look. The game result and the conversation provide different information.

For a child who prefers drawing, let them sketch the feature they chose and label the source. For someone who enjoys words, ask for a caption under each name. Keep the factual question the same while changing how the child responds. These are optional parent-led adaptations.

A reusable comparison checklist

• We chose two named animals and a reason to compare them.
• We asked the same questions of both.
• We separated written facts, illustration details and our own questions.
• We kept a source beside the comparison.
• We stopped with one supported sentence and one unanswered question.

Check the current iPhone and iPad edition before installing. The checked listing requires iOS or iPadOS 18.6 or later and offers a free core app with optional purchases. Review the available content before planning an activity around a particular era.

Common questions

Does Dinopedia include only dinosaurs?

No. Its stated scope is prehistoric creatures, so choose and name your comparison carefully.

Do we need exact size measurements?

Only if size is your question. Keep units and measurement type consistent, and preserve any uncertainty or estimate in the source.

What if one answer is missing?

Write that you did not find it in that source. It becomes a useful research question rather than a reason to guess.

Does completing this activity prove learning progress?

It gives you a conversation and a supported comparison to revisit. It is not a formal assessment or a guarantee of an educational outcome.
