Paleontology

Gideon Mantell is famous for his discovery of Iguanodon. He also gave it its name, which means, "iguana tooth."

fossils are preserved animals or plants. but index fossils are fossils have wide distribution,many of them,evolves rapidly, and very easy to recognize.

Ammonites are index fossils.

The fossils were made only in a certain short time period.

usually an asteroid decintigrates before it hits the earth.

If an asteroid hit the Earth depending on its size, the smoke and debris of the impact would block out all sunlight to Earth. It would become unbearably cold and most life would die out. This is a theory of how the dinosaurs went extinct.this is right

During the Carboniferous period, the environment was warm and humid, with vast swamp forests covering much of the land. These forests eventually formed the coal deposits we see today. In contrast, the present environment is cooler and drier overall, with different vegetation and ecosystems in place.

When the animal dies its skeleton settles on the sea floor and is buried by sediment. that thickens and begins to turn to stone. The skeleton dissolves and a mold is formed. Minerals crystallize inside the mold and the cast is formed.

Fossil fuels are formed by natural resources such as dead organisms by decomposition (aerobic or mostly anaerobic). Fossil fuels have high percentages of carbon. It includes coal petrol diesel natural gas etc. It ranges from volatile materials like petrol to nonvolatile materials like coal.

The Permian-Triassic extinction event, around 252 million years ago, marked the end of the Permian period and the beginning of the Triassic period. It is the most severe extinction event in Earth's history, wiping out approximately 95% of marine species and 70% of terrestrial vertebrate species. The Cretaceous-Paleogene extinction event, about 66 million years ago, ended the Cretaceous period and led to the extinction of the non-avian dinosaurs and about 75% of all plant and animal species.

Alligators and crocodiles died out in Europe as the climate cooled in the Pliocene Epoch. The modern species Alligator mississippiensis, having evolved in the Miocene, continued into the Pliocene, except with a more northern range; specimens have been found in very late Miocene deposits of Tennessee.

Superposition is the methodology of younger sediments being deposited over older rocks. Paleontologists can determine the evolution or extinction of a species by looking at what fossils are either present or absent in a particular sedimentary layer.

The plant or animal must be encased in a substance that prevents destruction or erosion. Ice, tar, or layers of mud or clay can isolate the remains from sunlight, air, and consumption by other lifeforms. Over time, a mineralized form or a rock cast will result in a fossil or fossil imprint.

No, Neanderthals have not been found in the New World. Neanderthals were primarily distributed in Eurasia, while the New World was populated by other early human species like Homo sapiens and their ancestors.

The beginning of the Cambrian period is marked by the Cambrian Explosion, a rapid diversification of life forms that occurred around 541 million years ago. This event led to the sudden appearance of a wide variety of complex multicellular organisms in the fossil record, setting the stage for the subsequent evolution of life on Earth.

loss of habitat (change of habitat, turns too cold, too hot, too dry, too wet, ect)

loss of food (where we lose almost all plants and the in tire food chain collapses. along with us)

disease (self explanatory)

freezing (earth freezes over into another ice age)

flooding (after ice age effect the ice melts)

comets (the ash covers sun and kills plants. Same thing with loss of food except the ash can also possibly choke us)

super volcanoes (the ash covers sun and kills plants. Same thing with loss of food except the ash can also possibly choke us)

another animal claims the top of the food chain (mostly sci-fi)

The atmosphere of planet Earth is a key factor behind the existence of life, and human survival. Layers such as ozone helps shield against ultraviolet (UV) radiation. The percent composition of oxygen also serves as critical to breathing. Lastly the natural greenhouse effect caused by the atmosphere has helped keep temperatures habitable.

These "holes" are called the stomata. Carbon dioxide enters through the stomata, and through the process of photosynthesis, this carbon dioxide is changed to oxygen and then released through the stomata

An outwash plain is typically found at the terminus of a glacier and can be located downstream from the glacier in areas like river valleys or plains. This landform is characterized by sediment deposits carried and deposited by glacial meltwater.

The Silurian period occurred from 443 million years ago until 416 million years ago. It saw the emergence of animals such as coral and fish that began quickly populating the oceans, and plants like the fern first appeared on the planet.

Many answers exist on the internet. And many references. Of course the easy answer is
a crystal formed from organic molecules. It seems that there are many interesting property's shown by these crystals.

To speed up the petrification process, you can increase the temperature and pressure of the environment where petrification is taking place. Enhancing the mineral content of the surrounding solution can also accelerate the petrification. Additionally, exposing the object to catalysts or enzymes that promote mineral deposition can help speed up the petrification process.

The sun emits solar energy in the form of light and heat. This energy is captured by Earth and is essential for supporting life on our planet through processes like photosynthesis and driving weather patterns.

Staying only means staying in a certain places during certain times of the day, like sleeping in a hotel, being in school etc. Living means doing things in a certain place. You sleep, eat, interact and live in a place. This is usually places like your home.

Mountains, canyons, and volcanoes are some examples of huge geological formations that form on Earth's surface due to processes like tectonic activity, erosion, and volcanic eruptions. These features play a crucial role in shaping the landscape and influencing ecosystems around the world.

It actually depends on what type. If you want to be a paleozooologist for example you need to learn paleontology(if any), geology earth sciences, zooology, physics, and chemistry and if ou want to be a micropaleontologist you would need to learn paleontology, geology, earth sciences, microbiology, physics, and chemistry and telescopes

A hardened and preserved footprint is an example of a fossilized trace fossil. Trace fossils are marks or imprints left behind by ancient organisms, providing insights into their behaviors and interactions with their environment.
