Question

Sol.(b) [Key Concept: Living Fossils — Archaeopteryx is NOT One] Archaeopteryx is NOT a living fossil — it is an extinct fossil (dead) found from Mesozoic rocks. It is a connecting link between reptiles and birds. Living fossils are organisms that have survived essentially unchanged for millions of years (like Sphenodon, Peripatus/velvet worms, and horseshoe/king crabs). Archaeopteryx is only known from fossils.
