Plant fossils include roots, wood, leaves, seeds, fruit, pollen, spores, phytoliths, and amber. Fossil land plants are recorded in terrestrial, lacustrine, fluvial and nearshore marine sediments. Specifically, pollen, spores and algae are used for dating sedimentary rock sequences. Though plant fossils are abundant in many local regions throughout the world, the remnants of fossil plants are not as common as fossil animals. Early fossils of these ancient plants show the individual cells inside the plant tissue.

The Devonian period saw the evolution of what many believe to be the first modern tree, Archaeopteris. This fern-like tree combined a woody trunk with the fronds of a fern, but produced no seeds. The Coal Measures are a major source of Palaeozoic plant fossils, with many groups of plants in existence at this time. The spoil heaps of coal mines are the best places to collect the things.

Web blog

Web logs, or blogs, are frequently updated online journals in which bloggers, those who write and maintain blogs, share their opinions about a variety of interests from international current events to favorite wines to travels near and far too local rock bands.

Blogs are created with software that is easy to use and can be set up within minutes. Blogs are fun, are easy to use and allow you to voice your opinion online in real time. Maintaining a blog does not mean that you have to make daily updates; however, if you do not make at least somewhat regular updates, visitors will stop checking for new content.
