Match each fossil with the layer where it’ll be present based on these conditions: dinosaurs existed before birds. corals existed between trilobites and amphibians. trilobites are the oldest fossils. dinosaurs are younger than amphibians. birds are the youngest species to be observed in this stratum.

Birds- Layer 5 (top layer)- The youngest

Dinosaurs- Layer 4

Amphibians- Layer 3

Trilobites- Layer 2

Corals- Layer 1 (bottom layer)- the oldest.

Explanation:

The earth has undergone a various geological process and a variety of living species existed and evolved over a long period of time, after its formation. These species lived during a different time period where there occurred variations in the earth's climatic condition. This occurrence of species along with other major events were divided into different division which describes the geological time scale.

From the above-given options, the corals were first appeared on earth in the oceans about 535 million years back during the Cambrian. After this, the trilobites came into existence some 520 million years back and lived from the Cambrian till Permian. The amphibians then cam about 370 million years back during the time of Devonian of the Paleozoic era and were abundantly distributed on earth. The Dinosaurs came after the amphibians, some 245 million years back during the Triassic period of the Mesozoic era. The birds are evolved from a particular species of a dinosaur but the modern-day birds were evolved after the Cretaceous-Tertiary mass extinction some 60 million years back.

Thus, from the bottom layer (oldest) to the top layer (youngest), the given fossils can be arranged as-

Birds- Layer 5 (top layer)- the youngest

Dinosaurs- Layer 4

Amphibians- Layer 3

Trilobites- Layer 2

Corals- Layer 1 (bottom layer)- the oldest.
