Paleontology

The answer that you are looking for is very simple the answer is a WALRUS. you are very welcome i can give the answer for anything ant time you need it! and finally you are very smart.

a. pex: it might have lived in a very wide geographic region

Mass extinctions are often associated with significant geological events such as volcanic eruptions, asteroid impacts, or dramatic shifts in climate. These events can cause widespread environmental disturbances that disrupt ecosystems and lead to the extinction of many species.

Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.

One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.

The United Kingdom is often credited as being the birthplace of the Industrial Revolution, which began around 275 years ago. This period of rapid industrialization and technological advancement led to significant social and economic changes that shaped the modern world.

The supercontinent known as Pangaea completed its formation during the Permian period, bringing together many of Earth's landmasses into a single large landmass.

A significant event that marks the end of one era and the start of a new one is referred to as a paradigm shift. This shift often involves a fundamental change in beliefs, practices, or systems that redefine the way society or an industry operates. Examples include the Industrial Revolution or the fall of the Berlin Wall.

The Triassic Period occurred before the Jurassic Period. The Triassic Period lasted from about 251 million to 201 million years ago, while the Jurassic Period followed, lasting from about 201 million to 145 million years ago.

During the Paleozoic Era, there were two major landmasses: Laurasia and Gondwana. These landmasses eventually broke apart through the process of plate tectonics and formed the continents that we recognize today.

Basically, this question doesn't have any one answer (due to different conditions of previous mass extinctions). But from a broad view, the change in environment (e.g weather, food sources etc) forced species to evolve or disappear. For example, species as large as most dinosaurs could not survive in todays world due to the fact that they would deplete their food source in a short period of time. During the cretaceous period, the climate was far warmer than now, allowing vegetation to flourish, which in turn allowed herbivores to flourish, thus providing food for predators. Change in climate also contributed dramatically, as reptiles (the previous dominant species on the planet) rely on an external heat source and being as large as they were, they needed a lot of it.

Essentially we all evolved from the same place, what you see in species today is the result of trial and error (on a genetic level) over millions of years in order to adapt as efficiently as possible to survive in a volatile and unpredictable world. You even find this in different races around the world who have adapted different skin types, facial features etc to suit the environment in which they have lived over many generations.

So essentially nothing really caused rapid evolution. Everything was in the process of evolving, however the changes which caused mass extinctions just changed the outcome of the end result. As a matter of fact there is a lot of evidence pointing towards the fact that everything still is evolving.

Geologists created the geologic time scale to organize Earth's history into units of time based on the sequence of events recorded in the rock layers. It helps in understanding the chronology of Earth's history, including the development of life forms and major geological events. The geologic time scale also provides a framework for dating rocks and fossils.

Reptilian scales and bird feathers are made of the same substance; keratin. Bird feathers evolved from degenerated dinosaurian (coelurosaurian?) scales. The feathers were probably first used for insulation or were perhaps used en massealong the arms to form 'traps' for catching insects.

The woolly rhinoceros (Coelodonta antiquitatis) is an extinct species of rhinoceros that was common throughout Europe and Asia during the Pleistocene epoch and survived the last glacial period. The genus name Coelodonta means "cavity tooth". The woolly rhinoceros was a member of the Pleistocene megafauna.

The information that paleontologists gather is called fossil data. This includes evidence such as fossils, tracks, and traces left by organisms that lived in the past. This data helps researchers to understand the history of life on Earth and how organisms have evolved over time.

In this time the world was still being created, in my opinion there were still lots of ice ages and floods from storms...basicly during this time the sea level was constantly going up and down and never stopping.

Dinosaurs didn't have fur because it likely evolved after they went extinct. One theory is that fur developed as a way for mammals to regulate their body temperature and protect themselves from the environment, which wasn't a challenge for dinosaurs during their time.

scientists don't know, it could have been loss of food, they probably ate dead ones until nothing was there, or a disease got in plants an poisoned the plant eaters and a carnivore came by and ate it, it died, and it continued.

Yes, conifers were common during the Mesozoic Era, which lasted from about 252 to 66 million years ago. They were one of the dominant plant groups alongside cycads and ferns during this time, especially during the Jurassic and Cretaceous periods. Conifers played a crucial role in shaping the diverse ecosystems of the Mesozoic Era.

Amphitrite is a sea goddess in Greek mythology. She was often depicted as living in a magnificent underwater palace in the sea.

Soft animal parts can become fossilized through a process called carbonization, where organic material is compressed and heated under sediment, leaving a carbon residue. This can preserve delicate structures like feathers or skin. Another way is through replacement, where minerals gradually replace the organic material, preserving the shape and detail of the soft tissue.

The largest divisions of the geologic time scale are:

Hadean Eon (4.6 to 3.8 billion years ago)

Archaen Eon (3.8 to 2.5 billion years ago; this is when the first bacteria existed)

Proterozoic Eon (3.8 billion to 542 million years ago)

Phanerozoic Eon (542 million years ago through today; this is when the first complex multicellular life forms evolved.)

being the first or earliest of the kind or in existence, especially in an early age of the world: primitive forms of life.

2.early in the history of the world or of humankind.

3.characteristic of early ages or of an early state of human development: primitive toolmaking.

4.Anthropology . of or pertaining to a preliterate or tribal people having cultural or physical similarities with their early ancestors: no longer in technical use.

5.unaffected or little affected by civilizing influences; uncivilized; savage: primitive passions.

The volcano near Naples is called Mount Vesuvius. It is famous for its eruption in 79 AD that destroyed the Roman cities of Pompeii and Herculaneum.
