AB - AVIAN flight is one of the most remarkable achievements of
vertebrate evolution, yet there is little evidence of its
early phases. Specimens of Archaeopteryx shed important
(albeit controversial) light on this evolutionary
phenomenon, but large morphological (and almost certainly
functional) gap between Archaeopteryx and modern avians
remain virtually empty until recently. Here we report a
new, exquisitely preserved, bird from the Lower Cretaceous
Konservat-Lagerstatte of Las Hoyas (Cuenca, Spain) which
provides evidence for the oldest known alula (bastard
wing). Crustacean remains found inside its belly also
provide the oldest direct evidence of feeding habits in
birds. The new specimen has numerous synapomorphies with
the Enantiornithes, but its unique sternal morphology,
along with other autopomorphies in the furcula and
vertebral centra, support the recognition of a new
enantiornithine taxon, Eoalulavis hoyasi. The combination
in Eoalulavis of a decisive aerodynamic feature, such as
the alula, with the basic structures of the modern flight
apparatus indicates that as early as 115 million years
ago, birds had evolved a sophisticated structural system
that enabled them to fly at low speeds and to attain high
manoeuvrability.

AB - Dinocephalian mammal-like reptiles have in the past been
known only from Russia and South Africa. The recent
discovery of anteosaurid dinocephalians in China has
important implications for the biostratigraphic
distribution of these early therapsids and has furthermore
revealed additional autapomorphies of the Anteosauridae.
