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.
In replacement fossils the body dissolves and minerals are left in its place. In permineralization, the water enters the cells of the organism and deposits minerals in the spaces inside them. Petrified wood is a permineralized fossil. Whole Body Fossils. Whole body fossils occur when an entire organism, including soft tissues, is preserved. Examples include insects entombed in tree sap, which hardens to become amber, and mammoths encased in ice. Footprints and Trackways. Footprints made by prehistoric animals walking through the mud sometimes harden and become fossils.
