Softer soils will hold the imprint better than soils/dirt that are harder. This was not made around the research we did because the research we did only told us about fossils not about the soils. I think that the sandy soils with fossilize better due to the fact that fossils are mostly found in sedimentary rock (sand, silt or clay). There are some minor differences we will take into thought like for example that sand cracks very easily when it is dry so we won’t we able move the plate. Although I think our experiment will work very well and we will get good results.
