Denver Museum of Natural History Royal Tyrell Museum , Canada. Great virtual tour. We wanted to visit, but weather was uncooperative. Amanda with trilobite model. She said it was very realistic and it was interesting to learn about.
Trilobites are kind of like a big version of roly-polys.
They have segmented bodies. The scientist showed us many fossils and let us touch them. Amanda learned that fossilized bones are much heavier than normal bones because minerals that turn into rock fill up the holes where the marrow used to be. He also told us about ammonites, petrified wood, and volcanic rock. Harrison says natural selection means nature choosing which creatures survive.
