At the roots of the mammalian family tree
Article Abstract:
Mesozoic mammal fossils are extremely difficult to find and collect, with most being fragmentary and based on isolated teeth and jaws. Ji, Luo and Ji have reported a complete preserved specimen from the Late Jurassic/Early Cretaceous deposit of Liaoning, China. It provides an insight into evolutionary relationships, indicating that Triconodontidae is not a natural group. The specimen also emphasizes the presence of homoplasy and the evidence from the skeleton overthrows the apparent dental likeness of the tricondonts to one another.

Neuroanatomy of flying reptiles and implications for flight, poster and behaviour
Article Abstract:
A comparison of the brain and vestibular apparatus in two pterosaurs are presented based on high-resolution computed tomographic (CT) scan. Constructed digital endocasts suggests neural integration of extensive sensory information from the wing, further enhancing eye-and neck-based reflex mechanisms for stabilizing gase.

Inside the oldest bird brain
Article Abstract:
An important example in the study of evolution is the Archaeopteryx. An analysis of a model of its brain using modern technology can answer many unanswered questions regarding this primitive creature.
