PangaeaSupercontinent

Triassic Period. Mixed mesophytic forest

China to the middle section of the North American continent.

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

PurposeTo separate pollen, spores

and remains of once living organisms

No Hydrofluoric Acid

To match the pollen and spores to their original

Materials. Clay . Hydrogen

peroxide. Computer .

Hyposodium Chlorite

. Distilled water

. Meshed screen (300)

. Electric scale

. Microscope

. Filter . Mortar and pestle

. Glacial Acetic Acid

. Pipettes

. Glycerin . Slides/ cover slips

. Glycerin . Sodium Hydroxide

. Hydrochlori

c Acid

. Test tubes

Protocol And Analysis #1 Mortar and pestle 300 mesh

screen1 part hydrochloric Acid to .2g clay4 part glacial acetic acid to .2g clayAdd a drop of the diluted acid to slide

+ clay.Observe under microscope

Protocol And Analysis #1 Mortar and pestle 300 mesh

screen1 part hydrochloric Acid to .2g clay4 part glacial acetic acid to .2g clayAdd a drop of the diluted acid to slide

+ clay.Observe under microscopeNot very usefulGlacial acetic acid attacks anything

with calcium in it

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

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

Protocol # 3Trial 1 Trial 2

Add 35 drops of glacial acetic acid

Add 35 drops of Sodiumhypo Chlorite

Set time limits of 5 min/30 min/45 min/ 1 hour/ 1 day

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

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
