Hello, the Weekly Dino Fact of the week on the Webosaur Blog is based on Trilobites!
Trilobites looked a bit like woodlice,but they swam,crawled, and ran on the seabed a very long time ago.Their bodies had lots of segments and legs, and as the Trilobite grew, it threw off its old shell for a bigger and new one.Old shells often became fossils, and these tell us that trilobites were the first animals with eyes.Their big,curved eyes could see above behind, in front, and sideways all at the same time!They were very succesful and lived before the dinosaurs.
