how do scientist know if a fossil is 62,000 years old and how do they know how dinosaurs lived eg how did they know it would take 40 years for a certain dinosaur to grow into a adult there also i heard that scientist believe they found out that 2000 years ago there was a pit of ice in a lake and this is what Jesus walked on and they also stated that there was a tsunami thousands of years ago in the red sea. they claim they discovered these 2 theories by studding the water and the sand.

When rocks containing fossils are sandwiched above and below by igneous rocks, the igneous rocks can be dated by radiometric means and the age of the fossiliferous rocks in between can be estimated. Such dating has been conducted so many times in so many places that index fossils in each stratum have been identified. Now it is usually possible to date fossiliferous strata soley by means of index fossils.
Studies of bone tissue make possible estimates of dinosaur age because bone tissue changes in characteristic ways as an animal gets older.

they take core samples, ice samples, look at strata layers, carbon date, correlate bones and fossils, relative dating, the methods are numerous.. as for the jesus walking on ice crap, umm who knows.

Deduction...once you eliminate the impossible,whatever remains must be the truth...

The age of fossils is not always easy to determine, but there are several methods. The first one is to date the rocks containing the fossil. When rock is formed, often radioactive elements are trapped within. Radioactive elements decay at a known rate, known as half-life, which is the period of time that 1/2 of the mineral will decay into another element. By measuring the amount of radioactive elements and their decayed product, one can then figure out how long the rock has existed. By measuring the age of the rock just above and just below the fossil, one can get a good estimate of the age of the fossil. Another method is to find out what kinds of fossils are found alongside the dinosaur fossil. Since different layers of rocks, and therefore different periods of geologic time, are characterized by different kinds of fossils, one can tell which geological epoch the dinosaurs are from.
Dinosaurs are ectotherms, which means they rely on the environment to heat their bodies. Just like modern ectotherms, such as lizards and frogs, their bones show growth rings. By counting the growth rings, one can count the number of periods of growth the bones have experienced, or approximately how many years old the dinosaurs were when they died. By measuring the size of the dinosaurs, we know approximately how big they are when they are adult. There is of course always uncertainty as to whether an animal is a smaller species or an immature specimen of a larger species.
As for the Jesus legend, there have been much research done on the subject, and it appears that there was such a person who existed, but I have never heard about the ice and lake and walking on water story.
