Fossils

Paleontologists study fossils, archeologists study past human life, climatologists can study past climates, geologists can study various things about Earth's past - the point being that a number of different scientists may study fossils in their disciplines.

Scientists use the geologic time scale to outline the history of life on Earth. This scale divides Earth's history into different time intervals based on major geological and biological events. It includes periods, epochs, and ages that help scientists understand the timing and sequencing of events in the history of life on our planet.

Studying fossils to learn about Earth's past environments is a complex process that involves various scientific disciplines such as paleontology, geology, and biology. Scientists use techniques like carbon dating, sediment analysis, and fossilization patterns to reconstruct past environments. It can be challenging due to factors like incomplete fossil records, preservation biases, and interpreting data accurately.

Yes, the dinosaur fossil found in the Transantarctic Mountains in the summer of 1991 was the Cryolophosaurus. It was a large theropod dinosaur that lived during the Early Jurassic period, and its discovery provided valuable insights into dinosaur evolution in polar regions.

alfred wegener gave theory on continental drift explaining that the continents were all at one point one big land mass called Pangea. using the fossils found on costs and the fact that the continents all fit together like puzzle proved it. but during his time the theory wasn't excepted because he couldn't explain why:)

Paleontologists study fossils and ancient life, including, but not limited to, dinosaurs.

A fossil that looks like a spiral or a ram's horn is called an ammonite. Ammonites were marine creatures that lived millions of years ago, and their distinctive spiral shape makes them easily recognizable in the fossil record.

Kyron Horman, a 7-year-old boy who went missing in Portland, Oregon in 2010, has never been found. The case remains open and investigations are ongoing.

Fossils of starfish can be found in various marine sedimentary rock formations around the world, particularly in regions with well-preserved fossil records such as the United States, Germany, and Australia. These fossils are often discovered in ancient coastal areas or seabeds that have been uplifted over time.

Fossils can provide information about the types of plants and animals that existed in prehistoric environments, as well as the climate and geographical conditions during that time. By studying fossilized remains, scientists can reconstruct ecosystems, food chains, and habitats from the past, helping to understand how environments have evolved over time.

Yes, radioactive isotopes like uranium-lead, potassium-argon, and rubidium-strontium are commonly used to determine the absolute age of rocks through radiometric dating methods. By measuring the decay of these isotopes in a rock sample and comparing it to the initial amount of parent isotopes, scientists can calculate the age of the rock.

Fossils provide valuable information about the history of life on Earth, including how organisms evolved and diversified over time. They also offer insights into past environments, climate conditions, and interactions between species. By studying fossils, biologists can better understand the origins and relationships of different species, as well as make predictions about future evolutionary trends.

Igneous rock is formed by the cooling of magma - liquid or molten rock. Fossils won't be found in there for obvious reasons. We don't even bother to look for fossils in something like, say, basalt, which is an igneous rock. A link is provided to the Wikipedia article on igneous rock.

The method of Absolute Dating using Radiometric measures is most accurate as it provides an approximate, but yet also more accurate result, compared to relative dating which is only comparing the age of one fossil to others locally and globally, which does not define the age at all.

Fossils that are widespread geographically are commonly referred to as cosmopolitan fossils. These fossils are found in multiple locations around the world, indicating a broad distribution during the time period in which they were alive.

Apologies, but I do not know what unconformity you are referring to. However, I can tell you that conglomerate IS present as an unconformity in many cases due to the nature of it's formation. Conglomerate is often produced during a flash-flood, so all rock strata from the period appear interrupted by the unconformity of Conglomerate which was deposited very quickly, then after burial was cemented and lithified. My answer, therefore, is that conglomerate is common as an unconformity.

In ancient Athens, women would most likely be found in the home, taking care of household responsibilities and raising children. They were not allowed to participate in public life or political activities. Women's status and roles were limited in ancient Greek society.

It can provide evidence of the environment the area was in in the past. For example, if you found a fossil with tentacles, you could guarantee that it is a marine creature (as tentacles are useless on land). You can then go on to imply that the rock was also formed in a marine environment. An example is shale, which is formed in a tranquil marine environment. This gives evidence of the past environment and also climate. Coal is also a fossil. A coal seam is sure evidence of a warm climate and a deltaic/marshy landscape.

Special dig sites can be unlocked by completing specific tasks or reaching certain milestones in the game. Keep progressing through the story mode, completing side quests, and earning high ranks in battles to possibly unlock special dig sites. Exploration and talking to characters in the game world may also reveal clues on how to access these special locations.

Ancient volcanic ash deposits are important to geologists because they provide valuable information about past volcanic activity, including eruption timing, source location, and composition. By studying these deposits, geologists can reconstruct volcanic histories, understand volcanic hazards, and determine past environmental conditions. Additionally, volcanic ash can act as a time marker in geological layers, aiding in dating and correlating rock formations.

One example of a fossil record is an ammonite. These fossils often show signs of damage like teeth marks that can be used to determine old predators on the sea floor. Another is an fossil depicting early man, which can be used to see how humans have evolved physically and mentally.

Yes, scientists can use soil to help determine past climates through a field called paleoclimatology. By studying certain characteristics in soil, such as the types of minerals present or the ratio of stable isotopes within them, researchers can infer past climate conditions like temperature and precipitation patterns. This can provide valuable insights into how climates have changed over long periods of time.

The word 'evolution' can refer to both established fact, and to the theoretical model explaining observations in terms of what we know about that fact.

Evolution, the fact, refers to the observed phenomenon of the changing of allele frequencies in populations.

Evolution, the theory, refers to the theory that evolution (the fact) is a result of reproductive variation (eg. mutations), and is mediated by differential reproductive success (natural selection) to produce new forms.

Evolution, the theory, is as close to fact as any science can come. Note that the term 'scientific theory' does not have the same meaning as the popular vernacular 'theory'. In everyday use, the word 'theory' may be used to describe a mere hunch or speculation - whereas in science, a theory is a comprehensive, well-supported explanatory model, consisting of multiply verified hypotheses and independently verifiable facts and laws.

Evolutionary theory encompasses the central hypotheses of common descent and natural selection.
