What are micropaleontological proxies?

Micropaleontological proxies are like clues that scientists use to read a very old story written by tiny ancient creatures.

Imagine you find a jar full of tiny seashells in your backyard, they're so small, you need a magnifying glass to see them. These tiny shells are from microfossils, which are the remains of tiny ancient organisms like plankton or foraminifera that lived millions of years ago.

Like a Time Machine

When scientists study these tiny fossils, they’re not just looking at old seashells, they're using them to figure out what the Earth was like back then. These tiny creatures lived in different kinds of water and climates, so their shells can tell us about temperature, ocean chemistry, and even climate change.

It's like having a time machine that uses seashells as tickets!

A Clue from the Past

Scientists can look at how these tiny fossils are arranged or what they're made of to guess what the world was like millions of years ago. That’s why micropaleontological proxies are such powerful tools, they turn little ancient creatures into big clues about Earth's history!
