Paleopalynology

1. Paleopalynology By: Group 5 Analisa Ramnarine Ronny Rahman

2. Pangaea • Supercontinent • Triassic Period. • Mixed mesophytic forest • China to the middle section of the North American continent.

4. Mixed Mesophytic Forest • Grown in/ adapted to a moist environment. • Fossil bed in Idaho is a result of the forest, and has left behind remains of plant and animal species

5. Purpose • To separate pollen, spores and remains of once living organisms • No Hydrofluoric Acid • To match the pollen and spores to their original

6. Materials

7. Protocol And Analysis #1 • Mortar and pestle 300 mesh screen • 1 parthydrochloric Acid to .2g clay • 4 part glacial acetic acid to .2g clay • Add a drop of the diluted acid to slide + clay. • Observe under microscope

8. Protocol And Analysis #1 • Mortar and pestle 300 mesh screen • 1 parthydrochloric Acid to .2g clay • 4 part glacial acetic acid to .2g clay • Add a drop of the diluted acid to slide + clay. • Observe under microscope • Not very useful • Glacial acetic acid attacks anything with calcium in it

9. Protocol And Analysis # 2 • 3% hydrogen peroxide added to the 300 mesh screened clay • pipette to add a few drops of the diluted acid to the slide

10. Protocol And Analysis # 2 • 3% hydrogen peroxide added to the 300 mesh screened clay • pipette to add a few drops of the diluted acid to the slide • hydrogen peroxide did not change much

11. Protocol # 3

12. Analysis # 3 • Same broken pieces of barrels and pollen in slides • Chemicals did not destroy pollen, but the mortar and pestle

13. Protocol And Analysis #4 • Clay from the block + a drop or two, of distilled water unto the slide. • Place a cover slip on it and observe under microscope.

14. Protocol And Analysis #4 • Clay from the block + a drop or two, of distilled water unto the slide. • Place a cover slip on it and observe under microscope. • Simple and easy to do • so many preserved parts of organisms and pollen that we have captured
