Review Exercise for Section 23 Correct errors in adjective and adverb use.
In the following passage, correct any errors in adjective and adverb use.
Recently, paleontologists have discovered the complete fossils of five 110 million years old
ancestors of modern crocodiles. The fossils of Sarcosuchus imperator, which means “emperor of the
flesh eating crocodiles,” were found in an African ancient riverbed. The skull of one adult animal
measures four and a half feet long, and scientists estimate that the creature’s length would have been
more than thirty-five feet; modern crocodiles don’t rarely reach half that size. In a photograph released
by scientists at the University of Chicago, the skull of the Sarcosuchus looks enormously next to the skull
of a modern crocodile.
The skeletons of juvenile Sarcosuchus found in Africa provide fortunately clues to the lives and
habits of the giant prehistoric crocodiles. They did not grow especially quick: at forty years of age, the
creatures were not yet adults, and they may not have reached maturity until they were fifty or sixty. They
were covered with stiff bony plates that were similarly to armor, so they did not move lively. The
Sarcosuchus had smooth, stout teeth that worked good for grabbing and crushing its prey. Like its
present day descendants, Sarcosuchus had eyes and nostrils on top of its skull, so it was built totally
perfect for lurking underwater and grabbing prey on the riverbank. Other ancient reptiles may have been
more larger, but the prehistoric crocodile’s great similarity to its modern descendants allows humans
today to imagine the fearsome ancient creatures vividly. Most people who see the Sarcosuchus skull are
certain to feel relievedly that this prehistoric creature no longer roams the rivers of the earth.
