Feeding Mechanics in Spinosaurid Theropods and Extant Crocodilians
A number of extant and extinct archosaurs evolved an elongate, narrow rostrum. This longirostrine condition has been associated with a diet comprising a higher proportion of fish and smaller prey items compared to taxa with broader, more robust snouts. The evolution of longirostrine morphology and a bulbous anterior rosette of premaxillary teeth also occurs in the spinosaurid theropod dinosaurs...
متن کاملHomology of Facial Structures in Extant Archosaurs (Birds and Crocodilians), With Special Reference to Paranasal Pneumaticity and Nasal Conchae
Homology of virtually all major components of facial anatomy is assessed in Archosauria in order to address the function of the antorbital cavity, an enigmatic structure that is diagnostic for the group. Proposed functions center on its being a housing for a gland, a muscle, or a paranasal air sinus. Homology is approached in the context of the Extant Phylogenetic Bracket method of reconstructi...
متن کاملReproductive Traits of Non-avian Theropods
The reproductive biology of non-avian theropods, primarily maniraptorans, is revisited using recent fossil discoveries in the framework of the extant phylogenetic bracket. It is apparent that non-avian theropods shared some reproductive characters with crocodilians, some with birds, but also possessed their own unique features. Whereas the non-avian theropod reproductive system retained primiti...
متن کاملUnihemispheric sleep in crocodilians?
Reduced vigilance is the conspicuous cost of sleep in most animals. To mitigate against this cost, some birds and aquatic mammals have evolved the ability to sleep with one-half of their brain at a time, a phenomenon known as unihemispheric sleep. During unihemispheric sleep the eye neurologically connected to the 'awake' hemisphere remains open while the other eye is closed. Such unilateral ey...
متن کاملSuction feeding mechanics, performance, and diversity in fishes.
Despite almost 50 years of research on the functional morphology and biomechanics of suction feeding, no consensus has emerged on how to characterize suction-feeding performance, or its morphological basis. We argue that this lack of unity in the literature is due to an unusually indirect and complex linkage between the muscle contractions that power suction feeding, the skeletal movements that...
