CONCLUSIONS

  

The main advantage of this method is the low cost, therefore: 1) the technique here presented seems to be an excellent exploratory or small project procedure. 2) all the materials needed are easily accessible in any regular store. 3) it uses the absolute minimal amounts of chemicals – preventing damage to fossils and improving safety for volunteers, 4) the material recovered from the Lourinhã Formation is in an excellent state of preservation.

The main drawback is the small amount of sediment that can be processed (45kg/day, 4 volunteers working 4-5 hours) making this technique more suitable to smaller studies or reconnaissance investigations.

 

ACKNOWLEDGMENTS

We would like to acknowledge all Museu da Lourinhã 2008 campaign volunteers for all their hard work using this technique. We are also grateful for the contributions and constructive criticism of three anonymous reviewers.
