It almost goes without saying that I found no indications that this evaluation was warranted.The black corals of the Antipatharia are a group of colonial, sessile cnidarians that are […]

Scientists report first semiaquatic dinosaur: Spinosaurus
Scientists today unveiled what appears to be the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment. The fossils … Continue reading →

Mammals may have originated much earlier than thought
Paleontologists have described three new small squirrel-like species that place a poorly understood Mesozoic group of animals firmly in the mammal family tree. The study supports the idea that mammals — an extremely diverse group that includes egg-laying monotremes such as the platypus, marsupials such as the opossum, and placentals like humans and whales — … Continue reading →

Drivers of rich bird biodiversity in Neotropics identified
New research challenges a commonly held view that explains how so many species of birds came to inhabit the Neotropics, an area rich in rain forest that extends from Mexico to the southernmost tip of South America.

Although many fossils of titanosaurians have been discovered around the globe, especially in South America, few have been recovered from the continent of Africa. The new species, named Rukwatitan … Continue reading →
