The study is the first to draw a link between RBC size and microscopic traces of blood vessels and bone cells inside bones. They found that extinct mammal and bird relatives had smaller RBCs and were likely better athletes than earlier terrestrial vertebrates. The timing of RBC-size reduction coincided with Earth's greatest mass extinction 252 mya.

A team of geologists at the University of Rochester has discovered a new species of bird in the Canadian Arctic. At approximately 90 million years old, the bird fossils are among the oldest avian records found in the northernmost latitude, and offer further evidence of an intense warming event during the late Cretaceous period.

What do enormous dinosaurs have in common with tiny shrews? They are both four-legged vertebrates, otherwise known as tetrapods. In the course of evolution, tetrapods developed various body shapes and sizes - from the mouse to the dinosaur - to adapt to different environments. Their feeding habits range from pure herbivory to fierce carnivory, and their body structure reflects this feeding diversity. As plants are usually more difficult to digest than meat, herbivores are thought to need larger guts and more voluminous bellies. Nevertheless, this hypothesis had never been tested scientifically.

newly described species of extinct reptile that roamed Texas more than 200 million years ago had a strikingly dome-shaped head with a very thick skull and a large natural pit on top that lends the appearance of an extra eye, according to a study released Sept. 22 in Current Biology.
