Our visit to Lessor's Quarry took us back in time to the Ordovician Period where we had the chance to imagine Vermont 450 million years ago.

Mr. Wright explaining how Vermont at one time was located below the equator.  Scientist know this from studying index fossils, such as trilobites, brachiopods, and bryozoans which lived in warm tropical water.

Writing our thoughts on what might have caused Vermont/North America to move from the equator to today's present location during the last 450 million years.

Identifying the rocks in the quarry and coloring it on our chart of the Strata of Western Vermont's geology.  

Running to find and identify fossils in Lessor's Quarry.

Not only did we find many fossils, but also located calcite and quartz veins.

These two students identified  bryozoans located in this limestone rock from the Glen Falls formation.

On top of this rock three students located a group of brachiopods (marine invertebrate whose shell consists
 of two valves).

These students were very excited because they believed that they had located a trilobite. They are now trying to identify this fossil using identification charts. 

Here is a close-up of a brachiopod with bryozoans surrounding it.
