Any of the terminal or smaller branches of an axon that terminates with specialized ending that releases neurotransmitters. Telodendria originally refer to the terminal branches of dendrites, now they refer to the main or terminal arborization of an axon. Word origin: Greek tÃ©los (end) + Greek dÃ©ndron (tree).
Permineralization is one of the ways in which a plant or animal can be turned into a fossil. During this process, mineral rich water seeps into the void spaces of an organism, leaving deposits of minerals behind that slowly build up, creating a cast of the organism.
Fossils are the preserved remains of plants or animals. For such remains to be considered fossils, scientists have decided they have to be over 10,000 years old. There are two main types of fossils, body fossils and trace fossils. Body fossils are the preserved remains of a plant or animalâs body. Trace fossils are the remains of the activity of an animal, such as preserved trackways, footprints, fossilized egg shells, and nests. When asked what a fossil is, most people think of petrified bones or petrified wood. Permineralization is a process. For bone to be permineralized, the body must first be quickly buried.
