Precambrian Animal

What is the Precambrian Time?
     This is the Precambrian Time...


Ammonite

Ammonites are a Precambrian animal.  They are part of the class of sea animals called cephalopods.  This class of mollusks is the smartest of its kind.  The body of an ammonite is divided into chambers, one of which has an opening.  The living part of the animal lives in the chamber next to the opening.  Ammonites can differ in size starting from half an inch to about six feet.  Ammonites are essentially the ancestors of sea snails that we see today.  They truly are unique and interesting Precambrian creatures.

The Burgess Shale

We have started the book called Wonderful Life by Stephen Jay Gould.  The book first introduces its audience to a place called the Burgess Shale.  Below, I have put the links to websites about the Burgess Shale.  I have also put a picture of the Burgess Shale on Google Maps along with a description of what is in the picture.





The Burgess Shale:

In this picture, I have located where the Burgess Shale Geoscience Foundation is- it is a house and writing in green towards the bottom of the screen.  I have also put a mark on Emerald Lake (where I would probably go if I went to the Burgess Shale)- it is a boat and writing in blue towards the top of the screen.  I created a path from one to the other- the path is bright yellow.  I also put a shaded area at the end of the path to show where I would imagine a boating dock to be/ where I would love to dock while doing water spots- it is a purple shaded region.
