New dinosaurs include ornithopod Gideonmantellia amosanjuanae
, bird Australopicus nelsonmandelai
, and the feather-preserving (possible) megalosauroid Sciurumimus albersdoerferi
is shown to use the same amount of energy for running whether with winter or summer fat reserves and the ability to sense day lengths even prior to hatching is found in Leucophaeus pipixcan
. Studies on adaptations in trochilids to cope with heavy rain, the cranial biomechanics of Diplodocus
(showing that it wasn't specialized for stripping bark), and the brain of Paraptenodytes antarcticus
are published. Supposed material of a Middle Jurassic abelisauroid from England is reevaluated, showing it to bear no convincing abelisauroid characteristics.
