Are cursorial birds good kinematic models of non-avian theropods?
(Universidad de la Frontera, 2019)
Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur ...
Hind limb morphometry of terror birds (Aves, Cariamiformes, Phorusrhacidae): Functional implications for substrate preferences and locomotor lifestyle
(Royal Society of Edinburgh, 2017-02)
The hind limbs of birds have long been considered a key feature in the conquest of different environments. However, the high level of morphological diversity encountered complicates the foundation of a good theoretical ...
Ontogenetic shape changes in the pelvis of the Greater Rhea (Aves, Palaeognathae) and their relationships with cursorial locomotion: a geometric morphometric approach
(Wiley Blackwell Publishing, Inc, 2020-06)
Knowledge of the ontogenetic pattern of morphological features is essential to improve biological interpretations. The study of morphological features of the pelvic girdle and hind limb apparatus throughout growth is an ...
New heterodontosaurid remains from the Cañadón Asfalto Formation: cursoriality and the functional importance of the pes in small heterodontosaurids
(Paleontological Society, 2016-11)
New ornithischian remains reported here (MPEF-PV 3826) include two complete metatarsi withassociated phalanges and caudal vertebrae, from the late Toarcian levels of the Cañadón Asfalto Formation.We conclude that these ...
A new ornithuromorph bird from the Lower Cretaceous of South America
(Society of Vertebrate Paleontology, 2021-10)
The fossil record of Early Cretaceous birds in South America has been restricted to members of Enantiornithes from the Crato Formation (Aptian) of Brazil. Here we describe a new genus and species of bird discovered at Pedra ...
Comparison of the Oxygen Diffusing Capacity of the Picui Ground Dove (Columbina picui) with Other Doves of Chile
(SOC CHILENA ANATOMIA, 2009-12-12)
We studied the respiratory surface density and the thickness of the air-blood barrier in the Picui Ground Dove
(Columbina picui), and compared it with Eared Dove (Zenaida auriculata) and Blacked-winged Ground Dove (Metropelia ...
First record and a new species of seriema (Aves: Ralliformes: Cariamidae) from santacrucian (Early-middle miocene) beds of Patagonia
(Taylor & Francis, 2009-06)
The extant seriemas are long-legged cursorial birds which represent surviving relicts in South America of an early gruiform radiation within the suborder Cariamae. Phorusrhacids, idiornithids, and bathornithids are also ...
Paleobiology and paleoecology of an arid-semiarid Miocene South American ichnofauna in anastomosed fluvial deposits
(Elsevier Science, 2009-12)
Miocene deposits of the Toro Negro Formation in La Rioja province, Argentina, host a rich vertebrate and invertebrate ichnofauna. Trace fossils are recorded from the lower part of the Lower Member of the Toro Negro Formation ...
Morphology of the forelimb of Psilopterus bachmanni (Aves, Cariamiformes) (Early Miocene of Patagonia)
(Springer Heidelberg, 2015-05-12)
Psilopterines are the smallest and most gracile predatory birds belonging to the large terrestrial Phorusrhacidae, which were abundant during the South American Tertiary. Two taxa are recognized from the Santacrucian (late ...
Comparison of the oxygen diffusing capacity of the picui ground dove (Columbina picui) with other doves of Chile Comparación de la Capacidad de Difusión de Oxígeno de la Tórtola Picus (Columbina picui) con Otras Tórtolas de Chile
(Universidad de la Frontera, 2010)
We studied the respiratory surface density and the thickness of the air-blood barrier in the Picui Ground Dove (Columbina picui), and compared it with Eared Dove (Zenaida auriculata) and Blacked-winged Ground Dove (Metropelia ...
