Often considered the “first bird”, Archaeopteryx lived during the Late Jurassic (about 150 million years ago). This small, feathered dinosaur, about the size of a modern raven, measured around 1.5 feet (0.5 meters) in length and had a mix of avian and dinosaurian traits. It possessed teeth, clawed wings, and a bony tail like a dinosaur but had feathers and possibly the ability for limited powered flight or gliding.

Compsognathus longipes
Compsognathus longipes, often called the "chicken of the Jurassic", was a nimble, turkey-sized dinosaur known for its slender frame and agile build. Zipping through ancient landscapes some 150 million years ago, this predator likely hunted small prey like insects and lizards, aided by its sharp teeth and swift legs. With a delicate, bird-like structure and keen senses, it was a glimpse into evolution's path toward modern avian life.
