Studying of Bones

In lab today we looked at several different bones of different animals and focused on trying to label the bones. There was a lot of different information present but there were specific facts that stuck out in my head. We focused on what organisms were called when there were holes near the temple of the skull. Animals such as turtles would be considered an an anapsid. Meaning that they don't have holes near the temple of their skull which means that it's harder for them to move their jaws since the muscles don't attatch through the hole of the temples if their is no hole. A diapsid is a crocodile or a lizard, an animal that has two holes in their skull. This means that they are able to move thier jaw up and down and they are able to chew, something that turtles are not able to do. The other type is a synapsid which are mammals, there is a larger opening in the skull. This allows for mammals to chew and move their jaw up and down as well as side to side.
