Did you know it is thought that there are between 3-30 milions of animal species (mostly microscopic) in our planet and only 1.5 milions of them have been discovered? In 2006,17.000 species of animals and plants where discovered, which only represents a 1%?
Or that birds (yeah, "normal" ones, like pidgeons),according to evolution, are related to dinosaurs? They evolved from the same ancestor; due to adaptation, that ancestor evolved either to Raptors (like the ones from Jurassic Park) or to birds. Birds and raptors are on the top right: you can see their ancestor was called "Maniraptora"
