BUENOS AIRES -- (AP) -- Scientists working in Argentina's southern Patagonia
 region say they have discovered partial remains of what may be the longest
 dinosaur species on record.

 Carlos Muñoz, director of the Florentino Ameghino Museum of Natural Sciences,
 said Thursday that a team of paleontologists unearthed the bones of a
 plant-eating dinosaur thought to have roamed the earth 105 million years ago.

 The dinosaur is believed to have measured 157 to 167 feet from head to tail and
 weighed more than 10 tons. The creature is said to have been 27 feet longer than
 the Argentinosaurus, considered by some experts to be the largest dinosaur ever
 recorded.

 The new dinosaur, which had a small head and a long tail, has yet to be named or
 classified, Muñoz said.

 Muñoz said scientists working on a tip from a villager found a femur and two parts
 of a vertebra. The pieces of cervical vertebrae were nearly four feet high, he said.
