If an animal fossil was found in a rock, what would be the best way to determine its absolute age? *analyze the rock’s mineral composition

*take X-rays of the fossil and surrounding rock

*compare it to similar-looking fossils that have already been dated

*measure the ratio of a radioactive isotope and its decay product present in the rocks around the fossil

D

Explanation:

Absolute age is defined as the numeric age of fossils.

To identify the absolute age of a fossil,  the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.

Hence, the correct answer is "D".

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation
