MEXICO CITY (Reuters) - Mexican archeologists have discovered a maze of stone temples in underground caves, some submerged in water and containing human bones, which ancient Mayans believed was a portal where dead souls entered the underworld.

Clad in scuba gear and edging through narrow tunnels, researchers discovered the stone ruins of eleven sacred temples and what could be the remains of human sacrifices at the site in the Yucatan Peninsula.

Archeologists say Mayans believed the underground complex of water-filled caves leading into dry chambers -- including an underground road stretching some 330 feet -- was the path to a mythical underworld, known as Xibalba.

Spanish scientists have unearthed what could be Europe’s largest dinosaur boneyard, finding the remains of 65ft plant-eaters never before discovered on the continent. The palaeontologists believe they have found eight different species amid the 8,000 fossils discovered so far.

The range of species they are finding at the 80 million-year-old site and their state of conservation is virtually unparalleled in Europe and challenges long-held beliefs about the way in which dinosaurs became extinct.

“This is completely beyond what we expected to find,” Francisco Ortega, co-director of the excavation, told The Times. “This represents a huge leap in our understanding of the Upper Cretaceous (period).”

SALT LAKE CITY -- The duck-billed dinosaur was one of the world's most imposing herbivores with as many as 800 teeth and a body that could help it knock down trees.

Utah scientists have discovered one near the Arizona border that's even more threatening.

"It really is like the Arnold Schwarzenegger of dinosaurs -- it's all pumped up," said Scott Sampson, curator of the Utah Museum of Natural History.

The newly named Gryposaurus monumentensis, or hook-beaked lizard from the monument, was discovered in the Grand Staircase-Escalante National Monument in 2002 by a Pennsylvania furniture maker who volunteered to work at the site. Details about the dinosaur, including its name were published in the Oct. 3 edition of Zoological Journal of the Linnean Society.
