Uncertain Averaptoran Theropods
2013Several theropods have been briefly described and assigned to the clade Dromaeosauridae. However, some of these taxa may be excluded from such theropod group, based on several osteological features. Regrettably, most of these taxa were only briefly described, or are rather fragmentary, and consequently a complete cladistic analysis is beyond the ...

Fibular reduction and the evolution of theropod locomotion
NatureSince Hampé's classic developmental experiments in the mid-twentieth century1,2, the reduced avian fibula has sparked sustained curiosity3-6. The fibula transformed throughout dinosaur evolution from a columnar structure into its splint-like avian form, a change long thought to be of little biomechanical consequence3,6.

Binocular vision in theropod dinosaurs
Journal of Vertebrate Paleontology, 2006ABSTRACT The binocular fields of view of seven theropod dinosaurs are mapped using sculpted life reconstructions of their heads and techniques adopted from ophthalmic field perimetry. The tall, narrow snout and laterally facing eyes of the allosauroids Allosaurus and Carcharodontosaurus restricted binocular vision to a region only approximately 20 ...
