📋 What it is
Paleontology links biology, geology and chemistry — fossils tie living things to the rocks and time.
🗣️ Coach says
Fossils sit where several sciences meet. Biology tells us what the creature was; geology tells us the rock layers and age; chemistry explains how minerals preserved it and how dating works. Reading a fossil means connecting all three — life, rock and time together.
🧠 Memory hook
Fossils connect biology (the creature) + geology (the rock/age) + chemistry (preservation & dating).

What do you call a dinosaur that never gives up?
A Try-ceratops!
😲 Whoa!
By studying fossils in rock layers, scientists worked out that Earth is about 4.5 BILLION years old — and that life has existed for most of that time.
✅ Quick check: Which sciences come together when a paleontologist studies a fossil?
Say your answer out loud first — then reveal.
Biology (what the organism was), geology (the rock layers and age), and chemistry (how it was preserved/dated).
Paleontology integrates biology, geology and chemistry.
