Extinct Animals

Cyanobacteria.

Cyanobacteria are among the earliest forms of life and are thought to have evolved approximately 2.5 billion years ago. These bacteria are thought to have changed the atmosphere of the planet via nitrogen fixation. The first dinosaurs evolved approximately 250 million years ago during the late Triassic.

Every animal is a part of the food chain, so mass extinction can have very bad consequences for the species that survive. The surviving species must learn to work around the animal that has recently become extinct.

Water is essential for life as it is a universal solvent, a crucial component in metabolic reactions, helps regulate body temperature, and supports nutrient transportation in the body. Additionally, water is used for hygiene, agriculture, industrial processes, and generating energy.

Some dangerous animals in the Devonian period included jawless fish like Dunkleosteus, which had powerful jaws and sharp teeth for hunting. Other predators included early sharks and large eurypterids (sea scorpions), which were top predators in the ancient oceans.

older than the rock layer above it and can provide information about the time period in which it lived and the environmental conditions at that time. This helps scientists estimate the age of the rock layers and understand the history of the area where the fossil was found.

The extinction of tigers would have a significant impact on the overall ecosystem and biodiversity. It would disrupt the food chain and could lead to an increase in populations of prey species, affecting vegetation and other wildlife. Additionally, the loss of tigers would have cultural and economic implications for communities that rely on tiger-related tourism and conservation efforts.

Megalodon sharks are only known from fossilized teeth. Even before the Renaissance, megalodon teeth had been found, but they were believed to be the petrified tongues of dragons or snakes. In 1667, Danish naturalist Nicolaus Steno recognized that they were shark teeth. He revealed his findings in a book called The Head of a Shark Dissected.

It is important because the timing suggests a strong correlation between human arrival and the extinctions, indicating that human activities likely played a significant role in driving these extinctions. This can provide valuable insights into the impact of human presence on ecosystems and the importance of conservation efforts to prevent future extinctions.

Discontinuity surfaces (bedding planes and various types of unconformities), significant changes in mineralogy or grain size or changes in the types of fossils present in the rock may all help identify differing rock layers.

Because the Ice age died out all their food and that so they couldn't eat and when they went from one country to one country they would have to walk across the sea and they would fall through the Ice. BUT Humans was NOT the problem for the Mammoths extinction!!!!!!!!

Yes.

If a certain area has a group of animals living in a compact space, that species could become extinct easily. Also, a tsunami could cover a large area, harming species and the food chain which could later lead to extinction.

A geographic barrier that isolates a population into separate groups, preventing them from interbreeding, is most likely to lead to speciation. Over time, genetic differences can accumulate between the isolated populations, eventually leading to the formation of new species.

that answer i would say is pretty unpredictable. i would say not for a long time, but even though we probly have a while before all the animals go away, it still dosent mean we are loosing certain animals to certain things. i think it would be very plausible that a large number of animals will have dissapered by the end of my and your life time,but for all of them to become extinct, that would take so long its not even funny, though none of it is funny. But defenetly a very vast number of animals will be extinct if we dont start doing something about it now!!!!!!

Megalania is related to modern-day monitor lizards and is considered to be a giant, extinct relative of these lizards. Its closest living relatives are believed to be the lace monitors and perenties found in Australia.

Index fossils are useful to geologists as they are distinctive fossils that can be used to date the age of rock layers based on their known age ranges. By identifying and studying index fossils in rock layers, geologists can determine the relative age of the rocks and establish a timeline of Earth's history. This helps geologists correlate rock layers across different locations and construct a more accurate geological history of an area.

The trade off between saving an endangered species or recreating an extinct one is huge. Saving an endangered species can often be accomplished with land set aside for protection. Recreating an extinct species requires scientific accomplishment along with the creation of an area for the species to exist.

Archaeologists study artifacts, structures, and other physical remains left behind by past civilizations to understand their way of life, social structures, and technological advancements. By analyzing these material remnants, archaeologists can reconstruct the past and provide insights into how ancient societies lived and interacted. Through their work, archaeologists contribute valuable knowledge to our understanding of human history and cultural development.

the highest possibility outcome would probably be that the extinct animal would die within the it's lifetime since no animal today has a genome close enough to match a prehistoric animal enough to mate with it. animals today are far too evolved. also, the animals had a very large size and short lifespan because of the high levels of oxygen. there is much less oxygen on the earth today to supply them with the necessary amounts to live.

75 percent of plants, animals and microbes.

1. We kill many organisms from different types of species and even sometimes cause them to go extinct.

2. Pollution is dirtying the air, water, and earth. Litter and pollution can cause health problems and death in both humans, animals, and sometimes plants when there is too much.

3. We are cutting down forests so we can use the land, and otherwise messing around with the environment so that it is becoming unbalanced and very different from what it might have been had humans not existed - and more in a bad way than good.

Megalania fossils have been found in various locations in Australia, mainly in the eastern and southeastern parts of the country. One of the most significant finds was in the Naracoorte Caves in South Australia.

"Allosaurus robustus" is sometimes used for the fossil, but this is a nomen nudum or unofficial name.

Ammonites and nautiloids are extinct marine mollusks with coiled partitioned shells. Ammonites were abundant during the Mesozoic era, while nautiloids have survived to the present day with only a few species remaining. These shells are characterized by their chambers, which were used for buoyancy control and housing the soft body parts of the organisms.
