27. Types Of Species
Scientists have discovered thousands of dinosaur bones throughout the years and have discovered over 1,000 different species of non-avian varieties. There are multiple species of dinosaur classified within each genera, also known as genus, (which is the way scientists group species with shared characteristics) and there are over 300 valid genera named. Although there are only 300 recognized by the scientific community, some estimate the number to be closer to 1,800 with many still undiscovered.
