![]() | Scientists in Costa Rica are studying the death of at least 10 and 12 more ailing turtles in the southern zone. Universidad Nacional (UN) told the press that the environmental organization MarVia found the 22 turtles floating near Matapalo beach. Ten of the Kemp’s Ridley turtles died within days of bringing them to shore and biologists and veterinarians have no idea of what caused their deaths. According to Widecast Network, this occurs when creatures have been floating adrift in the water for a prolonged period. |

![]() | Their results challenge the conventional view that nearly all theropods hunted prey, especially those closest to the ancestors of birds. Rather, Zanno and Makovicky show that among the most bird-like dinosaurs — known as coelurosaurs — plant eating was a common way of life. «Most theropods are clearly adapted to a predatory lifestyle, but somewhere on the line to birds, predatory dinosaurs went soft,» Zanno says. Theropods are a group of bipedal dinosaurs colloquially known as «predatory» dinosaurs. Among theropod dinosaurs, all modern birds and several groups of their closest extinct relatives belong to a subgroup known as Coelurosauria. Coelurosauria also includes the iconic hunters Tyrannosaurus and Velociraptor. Most coelurosaurs were feathered. The most intelligent dinosaurs and those with the smallest body sizes also belong to this group. |
