 Welcome to the Voice of America's Newswords. The remains of a baby cave lion found in Russia date back 28,000 years. Preserved Researchers named the lion Sparta, found in a thick layer of frozen soil in Siberia. They say it was one of the most well-preserved ice age animals ever found. Its fur, organs, and skeleton were still in place. If something is preserved, it has been kept in a good condition for a long period of time. To preserve can also mean to keep something safe from harm or loss.
