ICYMI: #Arizona's Petrified Forest contains #trees from 200 million years ago that turned to stone when groundwater rich in silica replaced #wood with quartz crystals.
Scientists study these fossilized #ecosystems to understand which species adaptations helped survival during #climate shifts. The specialized vs. flexible trait question offers clues about current species facing human-made #climatechange. These ancient logs give us a window into #Earth's past that might help inform our future.
