Aphanosauria archosaurs (apart from specialized forms like pterosaurs or theropod dinosaurs). The pelvis (hip) of aphanosaurs shares many similarities with those of early dinosaurs and silesaurids as well as the unrelated poposauroids. Most of these traits can be found in the ischium, a plank-shaped bone which makes up the lower rear branch of the hip. For example, each ischium (on either side of the hip) contacts each other at the hip's midline. This contact is very extensive, although they are not completely fused due to the contact not extending to the upper edge of each bone. In contrast, pterosaurs, lagerpetids, and
Meat on the bone value can be hard to judge as the bone part of the product is inedible. Various portions may contain a greater or lesser proportion of bone. The presence of bones may make meat products more bulky, irregular in shape, and difficult to pack. Bones may make preparation and carving more difficult. However, bones can sometimes be used as handles to make the meat easier to eat. Foot-and-mouth disease (FMD) is a contagious disease affecting cloven-hoofed animals. Because FMD rarely infects humans but spreads rapidly among animals, it is a much greater threat to the agriculture industry than to human health.
