Fossils

The seaside is a good place to look for fossils because it often contains exposed layers of sedimentary rock that are rich in fossils. The constant erosion from the waves can also help to uncover new fossils that may have been buried. Additionally, marine environments are known to have a high abundance and diversity of fossilized marine organisms.

Scientists most frequently use radiometric dating, in its various forms, to figure out the absolute age of fossils. Except for carbon dating (which is only useful for fossils less than ~70,000 years), scientists find the ratio of radioactive atoms, or isotopes, to stable atoms in rock samples. In carbon dating, the sample is taken directly from the fossil.

The use variants of the continuous decay equation (P=e^rt) to figure this out. If you know the initial isotope ratio (which is the same as the atmosphere at the time) and the half-life of the element (the amount of time it takes for half of the amount of the radioactive element to decay), then the age is easy to find out.

Paleontologists, from what I understand, generally use Potassium-Argon dating.

There are other forms of dating that you could look up. Amino acid racemization is based off of the reversal of the chirality (handedness) of organic molecules. John Wells of Cornell University used coral rings to find the number of days in a year when the coral was alive, then used geologically sound calculations to find its age (the Earth's spin is slowing down, so there used to be more days in a year). Molecular clocks are sometimes used as a form of dating, and assume that species have a relatively constant mutation rate over their evolutionary history.

And I'm sure there are plenty more. Geochronology is cool stuff.

In 1991.

Fossils of mollusks are more abundant than those of worm phyla primarily due to the hard, durable shells that many mollusks possess, which are more likely to be preserved in the fossil record. In contrast, most worms have soft bodies that decompose rapidly after death, leaving little to no trace. Additionally, mollusks have diverse habitats and a long evolutionary history, increasing their chances of fossilization. The combination of these factors contributes to the greater abundance of mollusk fossils compared to those of worms.

Biologists study life; they can be considered to be of two kinds:

zoologists study animals, and botanists study plants.

I would probably say,.... a frog.

The oldest humanoid fossils were all found in Africa.

Coral, limestone, coal

You can tell this tooth is from a carnivore(meat eating dinosaur). If the tooth was very long, it could possibly be from a large carnivore, like Spinosaurus, T-rex,Gigantosaurus,etc. -dino-b, the dinosaur loving expert

because sometimes the scientists don't find the fossils

Not much, they're pretty quiet.

Fossils show certain species underwent small changes over a period of years the rock in which the fossil is encased dates the fossil and so they can put them in order to show the progression of the physical changes

No, stromatolites are bacterial mats and have been around for at least 2,700,000,000 years.

Trilobites only appear in the fossil record about 526,000,000 years ago.

To the Devon corporation which is at rustboro city go upstairs in the corporation and talk to all the scientists one will revive your fossil leave the building go back talk to him again and he will give you lileep/anorith.

there are two i think 1 is the ancient ruins :get Tarbo and T-rex rank 12 fight Rosie with them and go see Dr.Diggins. 2 is the underground mole cave: after chapter 8 you go to Rivet Ravine and go into Cave tunnel four then when you find a spot that goes four directions with a VMM go up then left use th ladder to go into the cave where you can find Brachio, Tricera, Nodo, Zino, Megath, and Chelon. Hope This Helps!

1...........Limestone

2............Sandstone

3............Ash flows, or plume of ash rain.

4...........Mud slides

5...........Sea floor beds.

6...........algae in lake beds.

7........... Third rock from sun.

You will receive them both during the course of the game anyway, so it does not matter too much whether you choose the root (Lileep) or the claw (Anorith) fossil.

Have a space in your party.

Take it to Oreburgh City Museum

Give it to the scientist to the north of the room

Walk out

Walk in and take the Pokemon from the scientist

P.S He will always say your late no matter how quick you are ;)

Go to see the man in the bottom right corner of the second floor in Devon Co. He'll take the fossil and when you come back to him in a few hours it'll be a Pokemon!

the first way is in the desert in mirage tower at the top you get to choose root fossil or claw fossil root fossil- lyleep claw fossil- anorith~ the other one will be found in the hole the digger made in the house on the route next to falarbor

you have to go to cold feet glaicer(or green horn plains(may not be there sometimes))and you talk to onnga oonga oonga.then if u want to get tarbo head tap yes(she has to say:Tarbo Head easy)and ull et the esaist way!

hi im jessy zuniga and he is not your best friend! he is not your best friend! he is not your best friend!

An Archaeologist

The fossils found at the top of a canyon will probably be younger than those at the of the bottom of the canyon because the fossils at the bottom of the canyon would have been there earlier when the so called "canyon" was once a flat land, so as time went by, the flat land began growing and getting taller and finally became a canyon so the fossils at the top of the canyon WOULD be younger than those at the bottom because the bottom fossils were there before the top of the canton even existed.
