This may look like a fossil fish tail, but it’s actually a 66-million-year-old palm frond! The hadrosaur we’re working on was buried in a sandy streambed after it died and is mixed together with a lot of plant remains that were also buried there. It’s rare to see plant remains so well preserved in a setting like this because the sand is often too course to preserve fine details, so this is a lucky find!
What kind of plant environment was our hadrosaur living in? “Based on other sites nearby where we have more complete paleofloral records, folks draw a comparison to a warm, wet swampy environment—think of the Mississippi River delta today. We find conifers (e.g., swamp cypress-type plants), broad leaved angiosperm trees (sycamores, willow relatives), palms, ginkgos, etc.” - Paige Wilson Deibel, Burke paleobotany collections manager.
