Owl Pellet Lab

What happened was my partner (Mary) and I unfolded the pellet for the aluminum casing and weighed it in grams. After finding the weight, we measured the length and width of the owl pellet. The, we deconstructed the pellet and took out all the bones that were stuck in it. We then took all of the bones and tried to put it back into the place of the original animal. After comparing each bone to the manual, we found that we had a vole. Based on our picture, it is very clear that the back leg (upper leg bone and lower leg bone) and shoulder blade match. 

The bones are similar in which humans and voles have a fibula part of the lower leg bone. Second of all, humans have a femur bone as well. Animas have a humerus on their upper leg and humans have it on their arm. The difference between voles and humans are that other animals can have 7 cheekbones while humans only have two. Voles have thick hair all over their bosies while humans only have fine thin hair all over their bodies. Humans also have more teeth and ribs than volesz
