SPACE.com – Looking for fossils in old rocks is a tough job. Body parts

you will find any evidence that life was once there. One question facing
scientists is: Just how far back in time can we go before the traces of life
are completely lost?
LiveScience.com – A catastrophic event 72.5 million years ago left a herd of giant, horned dinosaurs buried to become fossils. Now scientists have identified the extinct creatures as a new species.
Reuters – Scientists have unearthed the remains of a large meat-eating dinosaur with a breathing apparatus much like a modern bird, fortifying the link between birds and dinosaurs and helping to explain the evolution of birds’ unique system of breathing.
LiveScience.com – A huge carnivorous dinosaur that lived about 85 million years ago had a breathing system much like that of today’s birds, a new analysis of fossils reveals, reinforcing the evolutionary link between dinos and modern birds.
Dinosaurs did not proliferate immediately after they originated, but that their rise was a slow and complicated event, and driven by two mass extinctions, according to new research.
The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina’s Rio Colorado is helping to unravel how birds evolved their unusual breathing system.
