Preservation of Ancient Organisms

The video explores various natural preservation methods that allow parts of once-living organisms to last for thousands or even millions of years. It discusses how substances like asphalt and tar, amber, and freezing conditions have preserved ancient animals and plants. Examples include the LA Brea tar pits, where animals like saber-toothed tigers were trapped and preserved, and amber, which perfectly preserves insects. The video also covers how freezing has preserved woolly mammoths and how shark teeth found along the Atlantic Coast are remnants of ancient sharks.
