were herbivores but were no easy prey for Carnivores as they were able to do serious damage to even the mightiest carnivores.

Closing in on the group is the most famous node of dinosaurs and the final node before we reach the birds: Eumaniraptora. This node is represented by dinosaurs like the tiny Jurassic Park 2 star Compsognathus but that group continued to evolve for over 90 million years since the Early Jurassic giving birth to species like the most famous dinosaurs of all time: Raptors. They are a group of very poorly represented dinosaurs in the media but mostly famous as

the size of the Jurassic Park Velociraptors.

Microraptors were the only dinosaurs before Avialae who were able to fly by gliding from tree to tree and all of those factors gave the entire group of raptor the nickname “Protobirds” for creating the link between dinosaurs and birds.

Following the raptors were the birds, divided into Archaeopteryx who went extinct during the K/T extinction and living birds who lived during the Cenozoic and evolved into modern birds.

Birds, or Aves, survived the K/T extinction and went into the Cenozoic and diversified and adapted, lots of bird species went extinct while lots still live to our day from chicken and ducks to owls and eagles to emus and ostriches. The extinction of the dinosaurs didnt really mark the end of the Dinosauria clade but rather the downfall of the dinosaur dominance, because birds did dominate the planet for some time via the apex predator of the early Cenozoic, the Terror Birds, or other birds who still live to our day and dominate their ecosystem.

mostly famous as Velociraptors from Jurassic Park. Velociraptors were actually very small compared to what we see in the movies being the size of a modern-day turkey, they were also almost fully covered in feathers and almost all raptors were covered in feathers but ranged in size from the crow-sized Microraptor to the Early Cretaceous Utahraptor and Deinonychus who were the size of the Jurassic Park Velociraptors.
