Zoologists determine the age of a bear mainly by examining the size and condition of their teeth. By analyzing the wear and growth patterns of the teeth, they can estimate the bear's age. Additionally, zoologists may also use other methods such as studying growth rings in bones or looking at physical characteristics and overall size to estimate the age of a bear.
measure the rate at which the stream erodes its bed i think i am not sure
by comparing its placement with that of fossils in other layers of rock
Uranium isotopes could be used to date rock of this age if they are present in the rock.
Radioactive dating can be used to estimate the absolute age of an object.
Age of a goat can be estimated until it has all its adult teeth - basically two adult teeth have erupted when it is one year old, four when it is two etc etc after it has all its adult teeth it is difficult to tell its age until they start falling out then it is termed broken mouthed.
One way to tell the approximate age of a border collie is by their teeth. If they have all their adult teeth and the teeth are bright white, the dog is probably approximately one to two years old. As a dog ages, their teeth become stained and worn. It is an estimate on the age of a dog because a dog who aggressively chews may have worn down teeth when only a couple of years old.
Yes, to some extent. By examining growth and wear patterns, as well as changes in tooth structure over time, forensic experts can estimate a person's age range using their teeth. This method is often used in forensic investigations when other means of identification are not available.

The vets look at their teeth to make a close estimate on their age. The wear on the teeth helps them figure it out, along with the cat's overall health such as weight and activity level.
Carbon dating
milk teeth
Teeth can determine a person's age by the sequence that the teeth appear at particular ages. Lines that grow on the enamel of teeth, helps to show the age.
the milk teeth starts exfoliating from 6-7 years of age
carbon-14 dating
Babies can be born with teeth.
The first of the baby teeth (also called "milk teeth" and "deciduous teeth") begn to fall out about age five. They are gradually replaced by the newly erupting adult teeth, a process ususally complete by age 12-13. The exception is wisdom teeth, which, if they erupt at all, begin to do so about age 18-19.
