Fossils

C14 (carbon) isotope (mass number 14 that is, in stead of 12) if it is of organic origin, eg. wood, coal, mummy's clothe

Paleontologists study fossils, which are the preserved remains of ancient organisms, while archaeologists study artifacts, which are objects made by past human cultures. Both fields aim to understand the history and evolution of life on Earth and human societies.

Those ball-like objects are known as concretions and they form when minerals precipitate around a central nucleus. In the case of quartz concretions, silica-rich fluids flow through sedimentary rock layers and deposit quartz around a nucleus like a shell or fossil, forming the spherical shape. Concretions can come in various sizes and shapes and are often found in sedimentary rocks.

There are over 1,000 species from 500 genera of extinct, non avian dinosaurs that have been found, which is estimated to only be a tiny fraction of the species that did exist. However, birds are considered dinosaurs. Today, there are over 10,000 species of birds that have been discovered.

Fossils found in rocks can help scientists correlate and match rocks across different regions because specific types of fossils can provide information about the age of the rocks they are found in. By comparing the types of fossils in different rock layers, geologists can determine the relative ages of those rocks and create a timeline of events in Earth's history. This technique is known as biostratigraphy.

Some Amish communities do restrict the use of fossil fuels due to their commitment to living simply and in harmony with nature. They may use alternative energy sources such as solar panels and wind turbines to meet their energy needs. However, there are variations in practices among different Amish communities.

Fossils, defined as the physical remains of past life, provide invaluable information to scientists. They not only provide a picture of a long-distant past, but also information that can be used to understand the evolution of today's plants and animals and clues for the future of our planet.

If water plants lived in an area of volcanic hot springs such as Yellowstone Park, the silica in the water would gradually be absorbed into the cells of the plants. This kills the plants over time but it also preserves their structure in a rock called chert.

The 410 million year old Rhynie Chert in Scotland is a good example of early plants preserved in this way.

When an isotope in the rock decays, a new isotope or element is formed. This process is known as radioactive decay, where the original isotope changes into a different element or isotope through the emission of particles or energy.

The earliest primate identifiable from the fossil record is believed to be a group of creatures called Plesiadapiforms. These small mammals lived around 65 million years ago and are thought to be ancestral to modern primates.

544 million years ago was the Proterozoic era. This was before visible life on the planet. This long ago the inhabitants wouldn't necessarily leave a fossil. If there is a lack of fossil evidence after this that means there was a mass extinction in this part of the world, and nothing survived to have children to leave fossils. Eventually another species will migrate in but until that happens there would be no fossil evidence.

Limestones are sedimentary rocks made of skeletal remains. Limestones are recognizable because they react with Acid.

Crystalline limestone are micro skeletons with large visible crystals.

Micritic limestone is lithographic limestone and it is basically fine grained mud with micro-skeletons.

Fossiliferous limestone is made with whole fossils in my experience mostly shells.

Coquina is parts of skeletons pressed together. The difference between coquina and fossiliferous is that coquina doesn't have whole fossils.

Lastly there is chalk. This is a lot of microorganisms remains pressed together.

fossil fuels produce carbon dioxide which contributes to global warming, heating uo the planet, and seeing as many power stations are located around the world that the effect that these gases have is incredibly big. in the future scientist expect that coal will run out in 101 years, gas will run out in 57 years and oil will run out in 43. in the future they could cause the world to be unhealthy because people would be trying to make more coal, oil and gas. mostly oil. to stop this we would just have to try and use less fossil fuels. instead of having 3 cars just have two. or take in turns to drive eachother to the same place, that would be saving some oil and it would last longer.....

This is not so. The term Fossil Fuel was coined by DJ Rockafeller who wanted to manipulate the markets and had organisations could agree to the term so that he couldf make a killing on what is in actual fact natural fuels generated by our planet. This has nothing to do with dinosaurs or similar being fossilized!

Petrified wood is usually silicified. Specimens could be washed with a mild detergent, small brush and plenty of water and left to dry naturally. Most petrified wood would be naturally resistant to weathering.

hard parts on the outside of the organism means that the potential fossil is more

likely to survive as increasing pressures are placed on the potential fossil when

sediments are placed on top.

The evolutionary evidence presented by mammals in Australia includes unique marsupial mammals like kangaroos, koalas, and wallabies, which are endemic to the continent. The presence of prehistoric marsupial fossils in Australia supports the idea of an ancient lineage of mammals distinct from placental mammals found elsewhere. The diversity and adaptations of Australian mammals, such as the egg-laying monotremes like the platypus and echidna, further highlight the evolutionary history of mammals in Australia.

A trace of a long dead organism could be a fossilized imprint, track, or remains left behind in sedimentary rock. These traces provide valuable information about the organism's existence, behavior, and environment in the past. Scientists study these traces to learn more about ancient life on Earth.

Mucrospirifer fossils are found in sedimentary rocks because these rocks are formed from the accumulation of sediments, which can preserve fossils over time. The organisms that formed mucrospirifer shells lived in marine environments where their shells could be buried and preserved in the sediment. Sedimentary rocks provide the ideal conditions for fossilization to occur due to the gradual accumulation and compaction of sediments over millions of years.

As of now, Madeleine McCann has not been found. She went missing in 2007 and her case remains unsolved.

the yellow dots on your lower screen radar are the fossils and you either have to dive or swim up on the dot to find them.

some of them needs special monsters to find them eg. Temnodontosaur to do deep dives, and Hendodus to dig etc.

Fossils found in the lowest geological strata are generally more primitive than those found in higher strata. This principle is known as the Law of Superposition, which states that older rocks are found below younger rocks in undisturbed layers, reflecting the progression of life forms over time.

Amber is the clear golden material where insect fossils can be found. It forms from tree resin that hardens over time, preserving insects and other organisms trapped within it. Amber provides valuable insights into prehistoric ecosystems and the evolution of insects.

Fossil evidence suggests that the earliest bacteria on Earth lived around 3.5 billion years ago. These ancient bacteria were simple single-celled organisms that played a crucial role in the early stages of life on Earth.

Yes, South America has been a known location for dinosaur fossils. Some significant dinosaur fossils have been discovered in countries like Argentina and Brazil, providing valuable insights into prehistoric life on the continent.
