Etymology: Omomyids are the plural of "omomyid," and the family name itself comes from the genus "Omomys," a name built from Greek roots that describe the animal's shape or features. The fossil group is named after that genus, so the word is a scientific label rather than an old everyday term. The family belongs to the early primates, animals that lived alongside and before the lineage leading to monkeys, apes and humans. Their fossils show small bodies and features such as grasping hands and feet, which point to a life spent moving through trees. Because the name was created by scientists to classify fossils, its meaning is tied to the genus it names rather than to any sense that ancient people used it. The "-id" ending is the standard suffix for animal families, which is why the plural simply adds an "s."
