2014年3月1日 · However, the crocodile lumbar vertebral joints were much stiffer than the thoracic joints in all directions. ‘It was a big surprise for us’, says Molnar. Also, the spine as a whole was more flexible from side to side, which is the opposite of the mammalian spine, but possibly provides the crocodiles with the flexibility required for their ...

2015年11月1日 · Using three-dimensional virtual models and morphometrics, we compared the modern crocodile Crocodylus to five extinct crocodylomorphs: Terrestrisuchus, Protosuchus, Pelagosaurus, Steneosaurus and Metriorhynchus, which span …

2019年3月15日 · The quadratojugals are located at the posterolateral portions of the skull, contacting the jugals anteriorly and anterolaterally, and quadrates medially. The quadratojugals contribute to the laterotemporal fenestrae’s posterior margins and within them send spine-like processes termed the quadratojugal spines.

2012年1月1日 · Crocodiles, alligators and gharials are the only extant representatives of the clade Crocodylomorpha, whose members span the continuum from terrestrial to aquatic. Early crocodylomorphs had more...

2019年6月26日 · The paper describes functions and the shape of the spine throughout the whole evolution of vertebrates and vertebrate embryos, from primordial jawless fish to extant animals such as birds and humans, highlighting its fundamental features such as strength, stability, and flexibility, which gives it huge potential as a basis for bio-inspired ...

2024年12月17日 · Crocodile - Swimming, Walking, Running: Crocodilian locomotion is the product of a unique body form. The spine is joined to interlocking bony plates of the dorsal scales by ligaments. Crocodiles engage in a complex courtship.

2020年2月3日 · Thus, we have created a three-dimensional atlas of the Nile crocodile brain based on MRI data that describes the telencephalon, diencephalon, mesencephalon, and rhombencephalon. For this study, one young Nile crocodile (Crocodylus niloticus) with a body mass of 2.8 kg and snout to tail length of 95.5 cm was used.

2014年2月27日 · Nile crocodile skeletal anatomy OK, so why spines? Understanding how the vertebral column works is crucial to understanding locomotion and body support on land, and inter-vertebral joint stiffness (how much the joints of the backbone resist forces that would move them in certain directions) in particular has been linked to trunk movements in ...

Using corrosion casting, we describe the anatomy of this vessel and its connections with the caval and hepatic venous systems in representatives from four crocodilian genera. The spinal vein arises from an enlarged occipital sinus over the medulla and extends the entire length of the vertebral column.

2003年12月1日 · Using corrosion casting, we describe the anatomy of this vessel and its connections with the caval and hepatic venous systems in representatives from four crocodilian genera. The spinal vein arises...
