Fossils

The theory of plate tectonics easily explains the distribution of mesosaurus. When mesosaurus was alive, all of the continents were massed together into the supercontinent Pangaea. Therefor, South America and Africa met because there was no Atlantic Ocean, so the distribution of mesosaurus makes complete sense.

It gives information to scientists about the past. It also provides a reference of time throught rock layers. It can identify and define geological periods of time.

Fossils in rocks are pretty much like clay.

The permeable rock bearing the groundwater is an aquifer. If the impermeable rock layer at it's base (known as an aquiclude) is of limited lateral extent such that the groundwater level away from this area is much lower, then it may be known as a perched water table.

Because that can change the WHOLE theory of dinosaurs.

It also means that a human either went back in time or lived with the dinosaurs thats why you wouldn't expect it.

fossil b is older new rocks get pushed to the top and older rocks go down

you can not mine in oreburgh mine but when you get to eterna city you can get the explorer kit and mine then. but still you need ALOT of patience because sometimes itfeels like they never show up. Good luce mineing hope this helped. =]

By guess and by golly for the most part. Actually, with experience, dinosaur experts have gotten a lot better about guessing which part goes where, but there were some funny learning mistakes. For example, where the first Iguanodon was found, one of its two thumb-spikes was with it, but since they only found one, the scientists reconstructing the animal put the spike on its nose! The famous feud between Marsh and Cope (the two great early dinosaur hunters) began which Marsh pointed out to Cope that he'd assembled his great discovery, the Diplodocus, with the skull on the end of the tail! Marsh wasn't always right himself, though: he once put an Apatosaurus body and a Camarosaurus head together.

The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.

chemical weathering by acid rain.

The climate at the time the fossile was preserved. :)

Watch world has many fossil watches to choose from. They range from casual to athletic styles. Go to their store or visit their site for more details.

40 million years ago
They started appearing in the Cenozoic period.

Not necessarily. It may be just a fracture.

what could you conclued if you found a fossil of a tripocal plant in a cold climate

Paleontologists can learn about ancient environments, extinct species, evolutionary relationships, and past climates by studying fossils. Fossils provide important evidence for understanding the history of life on Earth and how organisms have changed over time.

The discovery of a fossil's age can be determined through methods involving radiometric dating. Fossils must then be compared to other organisms of that time period to determine changes to it.

You go underground and just search. Skull fossils appear at random, but they aren't all that rare. You just have to search. Also, Cranidos Skull fossils can only be found in Pokemon diamond, and Sheildon Armor Fossils can only be found in Pokemon pearl.

As an absolute minimum, you'll be able to find fossil pollen in Pa. In most soils, and frequently in swamps.

When organisms died in a river or stream of some sort, they are covered in a layer of sediment, as time gos by the sediment hardens and is covered by another layer of sediment and so on.

in the scope of geologic time, how significant is the presence of humans?

because they are found by waters edge
