Initial Pellet

Our initial pellet looked like the one above. While the camera angle may be a bit misleading, it is about 3" and 9/16 of an inch, it was bout .5"-1" wide, and weighed 14.7 grams. It looked full of bones, as a skull is extremely easy to see, and it was one of the largest pellets in the bag.

Excavation

As we worked through the pellet, many bones were found including the skull above. We mostly used 2 pliers for excavating the bones, while we used certain picks to get some of the debris out after the initial excavation process had been completed.

Identification Process

When the bone is mostly excavated, it was handed over to the bone identifier. In this case, the previously found skull was cleaned some more before compared with the chart. After little time, it was identified as a rat skull, and this caused us to look for more of the rat's anatomy.

Mounting

As many of the rat bones became clean, we knew it was time to piece together the rodent. slowly and carefully the bones were identified and positioned in relativity to the first bone we found, the skull. Although the hands and feet are missing from the rodent, the pieces fit and we are left with (most of) a common rat skeleton!
