The correct answer is - False.
The trilobites are a marine type of animal that has been one of the most successful animals in the earlier stages of the history of life on this planet. They have existed for roughly 270 million years, from approximately 521 million years ago until 252 million years ago. Their beginnings are traced back in the Early Cambrian period, and they went extinct in the great mass extinction at the end of the Permian period.
So, the trilobites are a very common fossil in the time frame from 521 million years ago until 252 million years ago, but they went extinct than, so they are missing from the fossil records onward from that time, thus we can say that they are not common throughout the entire fossil record.

Answer:
Explanation:Egypt, country located in the northeastern corner of Africa. Egypt’s heartland, the Nile River valley and delta, was the home of one of the principal civilizations of the ancient Middle East and, like Mesopotamia farther east, was the site of one of the world’s earliest urban and literate societies. Pharaonic Egypt thrived for some 3,000 years through a series of native dynasties that were interspersed with brief periods of foreign rule. After Alexander the Great conquered the region in 323 BCE, urban Egypt became an integral part of the Hellenistic world. Under the Greek Ptolemaic dynasty, an advanced literate society thrived in the city of Alexandria, but what is now Egypt was conquered by the Romans in 30 BCE. It remained part of the Roman Republic and Empire and then part of Rome’s successor state, the Byzantine Empire, until its conquest by Arab Muslim armies in 639–642 CE.
Answer:
The stars mass (once it becomes a star) is inversely proportional to its lifetime as a main sequence star. A red dwarf can survive for many billions of years; a star that has twice the mass of the Sun, such as Sirius A, will have 25% of the Suns lifetime.
