This week we have been digging for fossils and working out the best ways to excavate them. We found out that brushes were brilliant for removing sand and that you can use large and small brushes in different ways. We loved revealing all the detail in the burried dinosaur fossils. Some of the fossils were hidden in hard rocks so the brushes did not help! We had to choose a different tool and get tough with the hammers. We found out that they worked best on a hard surface and we managed not to hit any fingers or thumbs!
