Which two words are domain-specific words?
In the 1860s, a fossil of an "avian" or flying dinosaur known as Archaeopteryx was found. "Scientists" identified it as a combination of bird and reptile. This discovery led to the theory that birds have evolved from "carnivorous" avian "dinosaurs". Archaeopteryx lived in the southern region of Germany during the Late Jurassic period when Germany had a tropical "climate".
