Restos fósiles

The video explores the history of life on Earth through fossils, which are remains or impressions of ancient organisms. Fossils form when organic matter is preserved by sediment or ice, and minerals replace the organic material. They can be bones, shells, or even whole organisms. The age of fossils is determined by their depth in the strata, with deeper fossils being older. Fossils reveal how species have evolved over millions of years. A paleontologist analyzes a dinosaur fossil, noting differences between northern and southern hemisphere species, illustrating evolutionary changes due to habitat separation. Fossils provide insights into the evolution of both extinct and extant species.

What is the primary process that leads to the formation of fossils?

• Melting of ice

• By their size

• By their color

What unique feature was found in the dinosaur fossil from the southern hemisphere?

• Wings

• A longer tail

• A bump in the leg bone

• Extra teeth

What do fossil remains help us understand about species?
