Barbourofelis fricki are in the eukaryotic domain because they have true nuclei. They are in the animalia kingdom because they are predators that obtain energy by eating other organisms. They are in the phylum chordata because they are deuterostomes with bilateral symmetry and have nervous systems. They are in the class mammalia because they are vertebrate animals that have hair, mammary glands, mothers that feed their young milk, are endothermic, and were young were given birth to. They are in the order carnivora because they eat meat, but not all the species in carnivora eat meat. They are in the family barbourofelidae which are similar to cats yet had a  “delayed eruption of the deciduous upper canine tooth”.  In 1970 they were given the genus species name Barbourofelis fricki having the largest and most specialized teeth of their group.


In this present day phylogeny Barbourofelis fricki, without any genetic evidence, would be grouped with the major clade Opistikonta. At some point in the life cycle of organisms in the Opistikonta clades have or had posterior cilia and flat cristae. There was a branch in the animals where they became multicellular. The next evolutionary adaptation was true tissues and from there animals like Barbourofelis fricki became triploblastic with bilateral symmetry. Bilateral symmetry allows for a more complex digestive system with a head, intestines, and an anus. With a head came a more complex brain and nervous system helping organisms to better sense and react to their environment, this process is also called cephalization. The branch deuterostome means that during the embryonic stage an organism’s anus develops before its mouth. Chordates adapted to have a notochord. In the chordate group are vertebrates with modified integumentary systems, endoskeletons composed of bone and/or cartilage, an increased metabolic demand because of their closed circulatory system, and as I already mentioned a well-developed brain. Barbourofelis fricki would fit into the vertebrate group because of its features such as fur, teeth and bones, head, intestines, and many of the adaptations above.
