A team of researchers from North Carolina State University and the Palo Alto Research Center (PARC) has found more evidence for the preservation of ancient dinosaur proteins, including reactivity to antibodies that target specific proteins normally found in bone cells of vertebrates. These results further rule out sample contamination, and help solidify the case for preservation of cells — and possibly DNA — in ancient remains. Leer más.

In 2003, a mysterious and surprising dinosaur was discovered that possessed not only wings on its arms but also long feathers on each leg forming a “hind wing.” This was a completely new and unexpected body plan for a vertebrate (backboned) animal. Named Microraptor, this enigmatic animal set off a firestorm of debate about the role of “hind wings” and their importance in the evolution of birds from Velociraptor-like ancestors. This debate continued for nearly a decade, but no one was able to provide an explanation that fit well with both anatomy and aerodynamics. Leer más.
