Seeing the forest with the leaves - clues to canopy placement from leaf fossil size and venation characteristics.

16 Dec 2009 Although a variety of leaf characteristics appear to be induced by light environment during development, analysis of ontogenetic changes in living broad leaved trees has suggested that a number of other traits also lumped into the classic 'sun' ... Read more...

Evolutionary development of the middle ear in Mesozoic therian mammals.

7 Oct 2009 The definitive mammalian middle ear (DMME) is defined by the loss of embryonic Meckel's cartilage and disconnection of the middle ear from the mandible in adults. It is a major feature distinguishing living mammals from nonmammalian vertebrates. We ... Read more...

A long-snouted, multihorned tyrannosaurid from the Late Cretaceous of Mongolia.

3 Oct 2009 Tyrannosaurid theropods are characterized by a generalized body plan, and all well-known taxa possess deep and robust skulls that are optimized for exerting powerful bite forces. The fragmentary Late Cretaceous Alioramus appears to deviate from this ... Read more...
