New studies have actually shown that there were far more types of dinosaurs than we could have ever imagined. In total t Mesozoic era, there was an estimated 1543-2468 different species of dinosaurs. If you break these species down into much larger broader groups of dinosaurs, then get three major groups. These three groups include Theropods, Sauropods, and Ornithischians. The TheroAmypods were the more carnivorous dinosaurs,

Sauropods were the long necked mostly herbivore dinosaurs and the Ornithischians were the bird like dinosaurs. Scientists have said that still these numbers are just educated guesses and that honestly there may have been a lot more species of dinosaurs than they even know about. One thing that leads them to this belief is the fact that there are over 10,000 types of birds alive today all with origins that can be traced back to dinosaurs.
