Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.
Answer:
idk bud i think its true but it may be false
Explanation:
Answer:
The correct option is C, a clam shell have a good possibility of being preserved because it has a hard body.
Explanation:
In evolutionary studies, preservation are made in the form of fossils or remnants.
For an organism to be preserved, it must not decay early and it should be hard enough. When an organism is buried quickly then it will take more time to decay and hence will have more chances to be preserved.
As the clam shells are hard so this quality makes them ideal enough to be preserved.
