01 Opening
Fossa beat 1 of 5

Fossa was a pangolin who dug for a living, and deep in the rock she kept finding messages from long ago: fossils. "A fossil is a clue," she'd say, brushing off the dirt. "Read it right, and it tells you the old world."

Fossa was part digger, part detective.

02 Fossa
Fossa beat 2 of 5

Fossa uncovered a fish fossil — high on a dry hill, far from any water. "Predict," she said. "What was this place like, long ago?" A lab-mate thought hard. "If a fish lived here… it must have been underwater!" Fossa's scales gleamed. "Exactly. The fossil is evidence the place has CHANGED."

A clue about an animal was also a clue about a whole world.

03 Fossa
Fossa beat 3 of 5

Then Fossa showed a cross-section of rock layers, fossils tucked in each. "Predict — which fossil is oldest?" A lab-mate pointed to the deepest layer. "Right! Undisturbed layers stack oldest on the bottom, newest on top." She read the layers like pages in order.

04 Fossa
Fossa beat 4 of 5

A lab-mate said only animals with bones can become fossils. Fossa smiled and brushed off a delicate leaf print, then a footprint in stone. "A common idea — but soft things leave imprints, and even a footprint is a fossil. A track means an animal walked right here." The wrong guess opened up what a fossil could be.

She never made anyone feel small for a first idea.

05 Closing
Fossa beat 5 of 5

At the end of the dig, Fossa laid out her finds and read the whole story: a warm sea, then a forest, then the dry hill of today.

"You read a place's whole past," said the lab-mate.

Fossa curled her tail, warm with quiet awe. Old rocks had once looked like just old rocks. But learning to read fossils — to see that a stone fish means an ancient sea, that layers are pages of time — made the ground beneath her feet into a library of long ago. And getting to read it felt like the greatest privilege of all.

Reading together with a grown-up? A card for the grown-up

For the grown-up: ask one question, then wait. When they answer, add one word to what they said. Tap the button when they have said something — that is one turn each, a circle. Nothing is recorded or kept.

Let them finish it

Say “Fossa reads fossils as evidence of the past — what lived here, …” and stop. Let them finish it.

Then say the whole line together: “Fossa reads fossils as evidence of the past — what lived here, and what the place was like long ago.”.

Now wait. Count slowly to five in your head. Their answer is worth the quiet.

Circles together: 0

The SciQuest ensemble
