Biologists Follow ‘Fossilizable’ Clues to Pinpoint When Mammal, Bird and Dinosaur Ancestors Became Athletes

BloodSmear_Huttenlocker_Images.jpg

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.

New Prehistoric Bird Species Discovered

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.
