Toddlers can sort the pottery pieces into piles of things that are 'similar' or 'different' (for example: pottery pieces that have the same relative size vs. other pieces).
Toddlers can also identify and name a variety of basic colors (red, green, yellow, etc.) and group like-colored pottery pieces together.
Children under three would generally have trouble drawing the 'artifacts' they find in the dig site on their corresponding spot on a grid paper or 'map', since they have generally not yet developed a symbolic understanding of how a small scale model relates to the specific place it represents.
Children at this age can, however, make marks on paper for each piece they find and "draw" their discoveries-even if the drawings don't look like that object that was found.

Toddlers enjoy searching for artifacts with brushes and shovels, and practice in using these kinds of tools helps them develop hand-eye coordination.
Children at this age may not realize that each tool has a particular purpose- many toddlers like to use brushes as shovels- but if given a variety of tools to try, they may discover during their 'dig' that some tools are better for some jobs that others.
Children at this age may have difficulty matching the ends of pottery pieces -and sticking them together with tape- all by themsleves. However, if a grownup holds the pottery pieces together, toddlers are able, and very eager, to apply masking tape to secure the pieces to each other.
