Fossils

Rocks with large crystals are typically found in igneous rocks that cooled slowly beneath the Earth's surface. These rocks are often found in mountainous regions or areas with active volcanic activity where magma can crystallize slowly to form large crystals. Examples include granite, pegmatite, and gabbro.

Amber is the type of fossil formed by resin sediments that have hardened in a hollow space. It is prized for its beauty and sometimes contains well-preserved insects or plant material.

Fossils found on the seafloor can be dated using techniques such as radiometric dating or stratigraphic correlation. By analyzing the rock layers and the types of fossils found in them, scientists can determine the age of the fossils and the seafloor where they were discovered. This helps in understanding the history of the ocean and the evolution of marine life.

A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.

The discovery of a fossil of an ancient fish atop a mountain suggests that the area was once underwater, possibly indicating plate tectonics and the movement of Earth's crust. It provides evidence of past geological changes and can help scientists reconstruct the history of the Earth's surface.

People want to know about fossils because they provide evidence of past life forms and help us understand the history of life on Earth. Studying fossils can also provide insights into evolution, ancient environments, and how living organisms have adapted over time. Additionally, fossils can help us make predictions about future biodiversity and environmental changes.

there are many layers in the earth's soil. you can see them clearly in canyons, for example. the lower the layer, the older. so if the fossil is found near the top, it's fairly recent. if it's way down below, it's really ancient. hope this helps.

Organisms that formed index fossils existed during specific time periods in Earth's history. These organisms lived in abundance, had a widespread distribution, and have distinctive features that make them easy to identify in the fossil record. By studying these index fossils, scientists can determine the relative age of the rocks in which they are found.

The oldest known bat fossil is from 52.5 million years ago and belongs to a species called Onychonycteris finneyi. This fossil was discovered in Wyoming, USA and provided important insights into the evolution of bats.

Yes, dinosaur fossils have been found on all continents, including Antarctica. Fossils from different regions provide valuable insights into the diversity and distribution of dinosaurs during the Mesozoic era.

Robert Scott, a British geologist, discovered marine reptile fossils, specifically of ichthyosaurs and plesiosaurs, in the Jurassic rocks of Lyme Regis in England. His discoveries played a significant role in our understanding of prehistoric marine animals.

Altered remains refer to any physical remains, such as bones or artifacts, that have been intentionally modified or changed by external factors, such as burial practices, rituals, or natural processes. These alterations can provide valuable insights into cultural practices, beliefs, and interactions with the environment.

Weathering can cause fossils to degrade by breaking them down into smaller pieces. For example, rain can erode the rock that houses the fossil, causing it to become exposed and easily damaged by physical elements like wind or further water erosion. Over time, this process can wear away the fossil and make it unrecognizable.

Many of the found fossils of Archeopteryx have the impressions of what appears to be feathers. This established a possible relationship between birds and dinosaurs. Because of the Archeopteryx fossil, scientists were able to theorize that birds evolved from, and therefore are the direct descendants of some dinosaurs.

There is no concrete evidence to suggest that a specific cavewoman named Lucy existed. However, the skeleton of a hominid known as Australopithecus afarensis, commonly referred to as "Lucy," was discovered in Ethiopia in 1974 and is an important early human ancestor.

Yes, fossils are evidence of continental drift because similar fossils have been found on different continents that are now far apart. This suggests that these continents were once connected, supporting the theory of continental drift.

Scientists have learned about the diversity of life forms that have existed on Earth, including the evolution of different species over time. Fossils provide insights into extinct species and their adaptations to changing environments, as well as clues about ancient habitats and ecosystems. By studying the fossil record, scientists can better understand the history of life on Earth and how it has been shaped by various environmental factors.

Oil and natural gas are often found together in underground rock formations, with one being formed as a byproduct of the other. This is because they are both derived from organic matter that has been buried and subjected to heat and pressure over millions of years.

Apatosaurus fossils can be found in the Greenhorn Plains area of the Poisonous Swamp. They are normally found in the "Dino" rocks that can be cleared by using the Drill Ability.

Those that have body parts that are already mineralized. eg. shells and bones. A coral reef is a prime candidate.

The answer is trace fossils, because over time there mothers' would leave trails of her footprints to her nesting area.This caused many people to believe that eggs are body fossils, but mainly, they are traces of the mothers body or area to sleep and care for her babies.

Yes, ammonites are good index fossils because they had a wide geographical distribution and existed for a long period of time. Their evolution is well-documented, making them useful for relative dating of rock layers.

Fossils can be found in many countries around the world. Some well-known fossil-rich countries include the United States, China, Mongolia, Argentina, and Australia. Each of these countries has unique geological formations that have preserved fossils from various time periods.
