MEXICO CITY—Archaeologists said Thursday they have found 10 sets of skeletal remains that may belong to U.S. soldiers who died during a battle in the 1846-48 Mexican-American war. The government experts said the shape of the skulls and bone measurements suggest the skeletons belonged to Americans who were killed in the battle of Monterrey on Sept. 21-23, 1846. Archaeologist Araceli Rivera said the height of the skeletons—between 5 feet, 7 inches (175 centimeters) and 5 feet, 9 inches—and "Caucasian" skull features indicated they were Americans.
