Avisauridae leg formed by fused metatarsals (the bones which comprise the foot in humans). As a result, members of this family are distinguished from other enantiornitheans exclusively by features of the tarsometatarsal and pedal phalanges (toe bones). Unlike in some prehistoric birds, avisaurid tarsometatarsals were not completely fused, with the distal (outer) parts of the metatarsals being separate from each other. The proximal (near) half of metatarsal III (the long bone in the middle of the tarsometatarsus) is convex from the front. The inside edge of this bone's trochlea (toe joint) has a bony tab which points downward, known as a
Philosophy and religion of the Tlingit and thus are the physical reminder of that being after its death. In the case of animals, it is essential that the bones be properly handled and disposed, since mishandling may displease the spirit of the animal and may prevent it from being reincarnated. The reason for the spirit's displeasure is rather obvious, since a salmon who was resurrected without a jaw or tail would certainly refuse to run again in the stream where it had died.
