Researchers shined a laser light on fossil leaves and found some surprising results. Instead of mere impressions of leaves, the fossils turned out to contain original molecules—persisting after millions of supposed years.  

Nodosaurs were tank-like dinosaurs, similar to ankylosaurs, covered with spiky scales and a pair of two-foot-long spikes—one protruding from each shoulder. Miner Sawn Funk encountered one during 2011 in Alberta’s Millennium Mine. The fossil turned out to be the best of its kind.
