Ancient sea cow remains discovered on California island
The 25 million-year-old fossil remains of a sea cow that lived in the waters off Southern California’s Channel Islands have been discovered by scientists.
The fossil skull and ribcage were found on Santa Rosa Island, about 50 miles northwest of Los Angeles, the National Park Service announced on Tuesday.
Researchers say the ancient remains may be from a previously unknown sea cow species, but they will not know for sure until the skull is analysed by an expert.
Some fossilised remnants of at least four other sea cows were also found nearby.
Sea cows are torpedo-shaped plant-eaters that graze in shallow waters and can grow up to 13 feet long. The only living species are the dugong and three types of manatee.
