By analyzing all this data, scientists can learn new ways to help control animal populations, determine what impact development might have on an animal population, and determine if there are enough individuals of a particular species in an area to allow for reproduction.
They look for the animal bones which are found in proximity to their settlements.
Scientists determine evolutionary relationships between animal phyla using evidence from comparative anatomy, fossil records, molecular genetics, and embryology. By studying similarities and differences in these aspects across different animal groups, researchers can infer how they are related to each other in the tree of life.
Scientists can examine the contents in coprolites. If they contain bones, teeth, etc., then they can determine the animal was a carnivore. If they contain only certain minerals that can be traced to plants, with no bone, teeth, etc., they can determine the animal was more than likely an herbivore.
The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.
The anteroposterior (AP) diameter of the chest measures approximately 20-30% larger than the lateral diameter. It is a common measurement used in radiology to assess the size and shape of the chest cavity.
Normally, scientists will examine the content of the animal's stomach and intestine to get an accurate reading on what the animal had eaten.
they look at the teeth.if the teeth are sharp,the animal eats smaller animals.Of course,fish with flat teeth eat plants. i wonder why you did not know.

Scientists first find out why the animal is getting endangered. Then, they usually start a campaign, such as "Help Save The (animal)!" The scientists can work with authorities to ban poaching from the area that the endangered animal lives in, or they can take in some of the animals and breed them. Scientists also tell pro. breeders about what they want.
Animal Scientists, specifically Bovine Practicioners or Bovinologists.
