1. fossils

   A fossil (from Classical Latin fossilis, lit. 'obtained by digging') is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host. There are many processes that lead to fossilization, including permineralization, casts and molds, authigenic mineralization, replacement and recrystallization, adpression, carbonization, and bioimmuration. Fossils vary in size from one-micrometre (1 µm) bacteria to dinosaurs and trees, many meters long and weighing many tons. A fossil normally preserves only a portion of the deceased organism, usually that portion that was partially mineralized during life, such as the bones and teeth of vertebrates, or the chitinous or calcareous exoskeletons of invertebrates. Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces (coprolites). These types of fossil are called trace fossils or ichnofossils, as opposed to body fossils. Some fossils are biochemical and are called chemofossils or biosignatures.

Their music is flavoured by a blend of blues, rock and psychedelia, along with Rupam Islam's vocal renditions of his characteristic psychoanalytical lyrics.

Examples of fossils in a Sentence

1. Olivier Lambert:

   We have been waiting for such fossils for decades.

2. Clark Bunting:

   Our national parks are a reflection of our nation, both past and present, and these seven new national park sites will further tell America's stories, bipartisan, congressional approval for protecting and preserving Harriet Tubman's heroic life and work, Columbian mammoths and Ice Age fossils at Tule Springs, and the complexity of the Manhattan Project continue to make our National Park System our country's best idea.

3. Juan Diego:

   As scientists we feel it is our job to unveil these priceless traces of life, so the whole world can know more about the past. But we have to be extremely careful that during the process, we don't benefit a group of people committing crimes against humanity, in the end, the credit should go to the miners who risk their lives to recover these amazing amber fossils.

4. Darryl Granger:

   Part of the misconception about its age came from mixing of fossils from different layers during early excavations, using this method, we can more accurately place ancient humans and their relatives in the correct time periods, in Africa, and elsewhere across the world.

5. Adam Marsh:

   It's a phenomenal specimen. You do not see something like that very often, so it's really significant for that in itself, but what it indicates is that there's probably more fossils out there, especially at Canyonlands, in this really important time interval.
