Why Washington’s First Dinosaur Fossil Is a Big Deal!
Researchers in the San Juan Islands studying invertebrate fossils (creatures with no spines) came across a dinosaur fossil embedded in a rock! It makes Washington only the 37th U.S. state to find a dino bone! Here's why that's so incredible:
Washington state was under water during dino times! The Rocky Mountains and the Appalachians were above water, but everything else was covered in water back then!
Sea creatures aren't considered dinosaurs.
So how did it end up in Washington? They think the corpse washed up on a beach that ended up part of what became Washington!
The bone is between 65 and 80 million years old. The species was something like a T-Rex, but they aren't sure yet what. Remember that dinosaurs disappeared 65 million years ago, so the bone is from the end of the era.
