Dallas ? Two University of North Texas astronomers think they’ve found two pieces of a meteor that alarmed numerous residents when it streaked across the Texas sky on Sunday.

“It’s black like charcoal. Underneath this crust the color of the rock is concrete like gray,” said Ron DiLulio, director of the planetarium and astronomy lab program at the University of North Texas in Denton.

DiLulio and Preston Starr, UNT’s observatory manager, said they found the pieces Wednesday in a pasture east of West, about 70 miles south of Dallas. They said the samples are the “size of large pecans.”

The astronomers placed the samples in ZipLoc bags to keep out the air. They planned to transfer the samples to membrane cases and take them to the university for additional study.
