What is Paleontology & What is a Fossil?

Welcome to the Fossil Huntress Podcast, the podcast where we dig into the past—literally! Join in the exploration of the fascinating science of palaeontology — that lens that examines ancient animals, plants & ecosystems from wee single-celled organisms to big & mighty dinosaurs.Learn about the interwoven disciplines of natural history, ecology, geology, conservation & stewardship of our world. Today, we’re talking about paleontology—what it is, what paleontologists actually do, and what exactly counts as a fossil. So grab your metaphorical shovel, and let’s get digging.I’m your host, Heidi Henderson, and today we’re going to crack open a topic that’s millions of years in the making. So first off, what is paleontology? It’s a big word, but let’s break it down.“Paleo” means “ancient,” and “-ology” means “the study of.” So paleontology is the study of ancient life. That means anything that lived on Earth long before humans showed up—from tiny trilobites to towering T. rex.But paleontology isn’t just about dinosaurs. It includes ancient plants, sea creatures, insects, and even microscopic organisms. If it lived a really, really long time ago and left behind a trace, paleontologists want to know about it.So how do we study life that’s been gone for millions of years?That’s where fossils come in.A fossil is the preserved remains or traces of a once-living organism. That could be bones, teeth, shells—or even footprints, burrows, or plant imprints. Some fossils are what you’d expect: hard bones turned to stone. But others can be things like petrified wood, fossilized poop—yes, that’s a thing and it’s called coprolite—or impressions of leaves.Fossils form over really long periods of time. Usually, the process starts when an animal or plant gets buried quickly under sediment—like mud or sand. Over time, more layers build up, pressure increases, minerals seep in, and eventually, the organic stuff gets replaced or preserved. Fast-forward a few million years and boom—you’ve got a fossil.If you would like to learn more about different types of fossils or head out virtually on some fossil adventures, head on over to Fossil Huntress HQ at www.fossilhuntress.com.
