| NEW FRONTIERS FOR DINOSAUR SCIENCE |
| Sereno's ongoing field work in Africa has yielded a menagerie of new dinosaurs. These discoveries have included the giant predator, Carcharodontosaurus, which rivaled Tyrannosaurus in size. Another find was the fleet-footed meat-eater, Deltadromeus, that has no close counterpart on other continents; and the spinosaur, Suchomimus. Giant long-necked plant-eaters, found in a communal death site, included the 60-foot long Jobaria. |

| 343 MILLION YEARS OF PRIMATE AND CARNIVORE EVOLUTIONARY HISTORY AT RISK |
| Washington, D.C. – Scientists have discovered that the greatest concentration of all primate and carnivore evolutionary history exists within those species found only in the 25 biodiversity hotspots. These species – whose combined evolutionary ages total 343 million years – represent genetic lineages that are vital to the future diversity, evolution and survival of these animals according a collaborative study published by the Center for Applied Biodiversity Science (CABS) at Conservation International and biologists from the University of Virginia, Charlottesville in the Feb. 19 issue of the Proceedings of the National Academy of Sciences (PNAS). |

| WORLD'S SMALLEST LIZARD DISCOVERED IN THE CARIBBEAN |
| The world's smallest lizard has been discovered on a tiny Caribbean island off the coast of the Dominican Republic. The newly discovered species not only ranks as the smallest lizard, but it also is the smallest of all 23,000 species of reptiles, birds, and mammals, according to a paper to be published in the December issue of the Caribbean Journal of Science by Blair Hedges, an evolutionary biologist at Penn State, and Richard Thomas, a biologist at the University of Puerto Rico. |

| SMELLING LIKE A GIRL TO KEEP WARM |
| In the spring, male garter snakes pretend they're females, gathering up to a hundred other males around them. What for? Simply to keep warm, says new research.
The findings, by herpetologists at the University of Sydney and Oregon State University, are reported in this week's issue of Nature. |

| YALE AND UNIVERSITY OF CHICAGO RESEARCHERS DISCOVER 40-FOOT CROCODILE FOSSIL, POSSIBLY THE LARGEST KNOWN SO FAR |
| The bones of a 40-foot crocodile that dined on dinosaurs and 12-foot-long fish have been discovered by researchers at Yale and at the University of Chicago in the Cretaceous rocks in Niger, Africa. |

| BABY SEA TURTLES USE EARTH’S MAGNETIC FIELD TO NAVIGATE ACROSS ATLANTIC OCEAN AND BACK |
| Working in Florida, scientists have found what they believe is the strongest evidence yet that baby loggerhead turtles "read" the Earth’s magnetic field to help them navigate the massive clockwise current that sweeps the northern Atlantic Ocean. |

| HUGE DINOSAUR FIND IN QUEENSLAND |
| The biggest dinosaur fossil ever found in Australia was announced yesterday at the Queensland Museum. Dubbed 'Elliott', the sauropod dinosaur was found near Winton in western Queensland.
Dr Steve Salisbury, honorary research fellow at the museum, said the fossil could represent the first evidence of a unique group of sauropods. |

| MYSTERIES OF THE STUMPY LIZARD REVEALED |
| Can you imagine giving birth to a child the size of a six-year-old? Or not being able to eat or breathe properly for the last third of pregnancy? Welcome to the unique world of the Australian stumpy-tailed lizard! |

| POISONOUS DINOSAURS REALLY EXISTED |
| Dinosaurs, spiting poison in the Jurassic Period Park movie, were just a Hollywood's invention. However, it turned out, that some dinosaurs could actually have a poisonous bite.
Dinosaur tooth relicts found in Mexico showed that some of their teeth has a longitudinal cavity for poison; dinosaur tooth structure was similar to that of some poisonous snakes. This is the first evidence of the fact that some dinosaurs were really poisonous. The fact that all animals who have a cavity along the back wall of a curved tooth are poisonous is another evidence of this theory. |
