No, the two are distinctly different animals. Aardvarks are of the genus Orycteropus and are medium size, burrowing animals that are native to Africa. They are thought to closely resemble pigs although not actually related. Anteaters are of the sub order Vermilingua and are known for eating ants and other small insects with their long tongues. They live in trees and are said to resemble bears. They are found in central and south America.
Trilobites are thought to have been a marine organism because the fossils are found in rocks that contain other salt-water animals. Trilobites are thought to be one of the earliest groups of arthropods.
