Fossil Preservation & Taphonomy
📋 What it is
Only rare conditions preserve a fossil; taphonomy studies what happens between death and discovery.
🗣️ Coach says
Becoming a fossil is RARE — most dead things rot or get eaten with no trace. Taphonomy studies the journey from death to fossil: quick burial (mud, ash, tar) protects remains, and over ages minerals harden them. Understanding what preserves — and what’s missing — keeps scientists from being fooled.
🧠 Memory hook
Fossilising is RARE; needs fast burial. Taphonomy = the death-to-discovery story (what preserved, what’s lost).

What do you call a Stegosaurus with a great vocabulary?
A Thesaurus!
😲 Whoa!
The La Brea Tar Pits trapped and preserved so many Ice Age animals in sticky asphalt that scientists have pulled out millions of bones from a single site.
✅ Quick check: Why is becoming a fossil so rare for most living things?
Say your answer out loud first — then reveal.
Most remains rot or are eaten before burial — only rare fast-burial conditions preserve them into fossils.
Fossilisation requires uncommon rapid-burial conditions.

Think of two dead leaves: one rots on top of soil, one is buried in mud — only the buried one might fossilise.
