Archaeopteryx, discovered in 1861 in Germany, combines dinosaur-like teeth and claws with bird-like feathers, making it a pivotal link in avian evolution from theropod dinosaurs.

Petrifaction occurs when minerals like silica replace original organic tissues, preserving the detailed structure of bones or wood as they are converted into solid stone.

Coprolites are trace fossils that provide direct evidence of prehistoric diets. They often contain remnants of undigested bones, scales, and plant matter.

Permafrost acts as a natural freezer by halting bacterial decay, allowing soft tissues and DNA to remain intact for tens of thousands of years.

Amber is fossilized resin, not sap. Resin acts as a tree's immune system, sealing wounds and trapping insects with its sticky, antiseptic properties.

Sedimentary rocks form as sediment accumulates in layers, trapping and preserving organic matter without the extreme heat or pressure that destroys biological remains.

The Mesozoic Era consists of the Triassic, Jurassic, and Cretaceous periods. It is commonly known as the Age of Reptiles due to the dominance of dinosaurs during this time.

The Triassic began after Earth's largest mass extinction. The first dinosaurs evolved during this period on the supercontinent Pangea about 230 million years ago.

Pangea was surrounded by a single global ocean called Panthalassa. This unified landmass allowed early dinosaurs to spread across regions that are now separate continents.

Sedimentary rocks preserve fossils because they form at low temperatures and pressures, unlike igneous or metamorphic rocks where extreme heat and pressure destroy remains.
