Page 1

Mira, Dev and their museum guide study a deliberately mixed tabletop display with Stegosaurus and T. rex models.

Eleven-year-old Mira adjusted the wooden frame around their museum exhibit. “Our time-window is ready!” Dev placed a paper fern between a Stegosaurus model and a T. rex model. Their guide, Leela, leaned closer. “Beautiful work. But could these two animals have met?” Mira stopped smiling at the display and started studying it. The window was a reconstruction, not a real time machine. Had they built a convincing picture of something that never happened? They needed clues before the museum opened.

Talk together: Find the two models. What information would you check before deciding whether they belong in one scene?

The children inspect a Stegosaurus museum model with back plates and a separate replica plate.

Leela brought a museum reference book. Stegosaurus lived in the Late Jurassic, roughly 150 million years ago. Mira examined its small head, broad back plates and spiked tail. “So the plates are not just decorations our artist invented.” Fossils preserved clues to their shapes. Dev drew the model beside a fern, then paused over his green pencil. “We have evidence for those plates. Does that mean we know their exact colour?” Leela smiled. “Keep that question. First, investigate your other visitor.”

Talk together: Compare the model’s back plates with the separate replica. Name one detail supported by fossils.

A T. rex museum model and a separate replica tooth help Mira and Dev compare fossil clues.

The T. rex belonged to the Late Cretaceous, about 68 to 66 million years ago. Dev compared a replica tooth with the pointed teeth in its model mouth. “Another clue,” he said. “And a much later animal!” Mira wrote down their approximate dates. Around 150 million and around 68 million were separated by about 82 million years. “Our models can share a table,” she said, “but these living animals could not have shared a forest.” Their beautiful scene had hidden an enormous gap in time.

Talk together: Use the approximate example dates: 150 − 68 = 82 million years. Explain why both can be dinosaurs without being neighbours.
