Deciduous in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Wood from deciduous trees is used in a variety of ways in several industries including lumber for furniture, construction and flooring (oak), ornamental, bowling pins and baseball bats (maple) and furniture, cabinets, plywood and paneling (birch). In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called abscission. In some cases leaf loss coincides with winter—namely in temperate or polar climates.
Dentition later that tooth emergence begins, the earlier the anterior teeth (I1–P4) appear in the sequence. Dentition, or the study of teeth, is an important area of study for archaeologists, especially those specializing in the study of older remains. Dentition affords many advantages over studying the rest of the skeleton itself (osteometry). The structure and arrangement of teeth is constant and, although it is inherited, does not undergo extensive change during environmental change, dietary specializations, or alterations in use patterns. The rest of the skeleton is much more likely to exhibit change because of adaptation. Teeth also preserve better than bone,
