and 18 haemal arches (bones from the tail) that include a sequence of 17 anterior and middle caudal vertebrae and their corresponding haemal arches found...

camellate. In the haemal arches from the bottoms of vertebrae near the front of the tail, the holes that they form with the centra - the haemal canals - are...

The tail of Procynosuchus is also unusually long for a cynodont. The long haemal arches would have given the tail a large lateral surface area for greater...

middle-aged adults. Many mammals have tiny spleen-like structures known as haemal nodes throughout the body that are presumed to have the same function as...

cavity contains the circulatory or haemal system. The vessels form three rings: one around the mouth (the hyponeural haemal ring), another around the digestive...

dorsal ribs, and six sacral ribs; five other caudal vertebrae with two haemal arches; a right femur; and pelvic girdle elements, including an ilium, ischium...

front to the back, rather than doing so more abruptly. Additionally, the haemal keel of Liasis dubudingala is pronounced throughout the trunk of the vertebrae...

facets (in the body) or haemal spines (in the tail), though Microbrachis did have small intercentra and Pantylus did have small haemal spines. In addition...

reduction of the neural spines when compared to the anterior caudals. The haemal spine takes on a rounded, hatchet-shaped appearance. The prezygapophyses...

(the water vascular system) and a haemal circulatory system, as most groups of animals have just one of the two. Haemal and perihaemal systems are derived...

well-pronounced process, and all vertebrae except for the farthest distal ones have haemal arches on them. Like the chalicothere Chalicotherium and unlike other mammals...

premaxilla, the size of the suprastapedial process of the quadrate and if the haemal arches were fused to the centra of the caudal vertebrae. Prognathodon was...

meet below the vertebrae, while those further down the tail form complete haemal arches with long ventral processes that become more pointed and tapered...

vertebrae, 5 cervical ribs, 2 dorsals, 9 dorsal ribs, 19 caudal vertebrae, 9 haemal arches of chevrons, ischia, and left femur. The skeleton was described as...

be located close to the body, lightening the neck. chevron Chevrons, or haemal arches, are bones attached to the underside of caudal vertebrae, forming...

both dentaries; teeth; cervical, a dorsal, sacral and caudal vertebrae; haemal arches; ribs; ilia, pubis and proximal ischia; left and distal end of right...

platycoelous (flat on both sides). Each caudal centra only articulated with one haemal arch at its back end, as opposed to one at each end in Dolichorhynchops...

length. It have features of the mosasauroids, with three vertebrae with haemal arches and procoelic centra, that suggest the possibility that these small...

juvenile adelogyrinid having at least 70. Most of these vertebrae lack haemal spines, indicating that the primary elongation took place in the body rather...

vertebrae extending ventrally to the ventral surface of the centrum; fused haemal spines." Designation of this subfamily followed many decades of confusion...
