Owl Pellet Lab


To start this lab, we were given an owl pellet. We broke apart the pellet using forceps and probes in search of bones from different animals. We believe that the organism we found was a pocket gopher. Through deductive reasoning and a test, we were able to determine that the teeth and skull shape and size of this animal were almost exactly the same as the diagram of the pocket gopher in the handbook. The pocket gopher skeleton and our human skeleton are similar because the skulls both seem to the same immoveable joint structure connecting the different parts of the skull. The humans and animals also have a spinal cord as well as a rib cage. The differences between the pocket gopher and the human include sharp front incisors, a different skull shape, and the pocket gopher has a longer neck segment.
