Scientists know that glaciers in the Pleistocene period wiped out all earthworm species present in Canada and the Northern Continental United States. The line the glaciers extended to in this period is known as the Wisconsin Glacier Line. The Southern limit of this line extends across Southern New York and Northern Pennsylvania. The Mastodon in our mastodon project might have been found very close to that Southern New York Line!

Here is a picture that Nicole was able to take with her iPad through the lens of the Stereoscope!!  It looks just like a worm to us, so we sent a picture to Dr. Buckler to get her thoughts.

We found perfect SHELLS!

These are some of the perfect shells we found ! So exciting!

Hi Dr. Buckler,

We have a question.  We found a GREEN piece of vegetation in the matrix – (we think).  It’s definitely dry, but it also has some color to it.  Is there any way at all that anything in the matrix could be green plant material?  It’s definitely a plant with little leaves.  We attached a picture.  Thank you for any advice on this.

Sincerely,
Maeve, AnnMargaret and Nicole

Green leaf found in Matrix?
Dr. Buckler’s  Response:
Well, That’s Fun!
There is always a chance of some “fresh” material contamination.  We fill the buckets (5 gallon) at the site and try to cover them with lids as soon as possible, but things happen.  If something happened with the bucket that that sample came from —it was opened by accident, the top broke during transport, a big wind came up before it was covered, etc.–there will be notes to that effect on the records for that bucket.  This is yet another reason the number on that bag is so important; if we find something like this, or what may look like a new species not found in the Pleistocene before, etc, we need to immediately go to the records of the dig and make sure there was no “foul play” associated with that bucket, and thus, that sample.
That does look like fresh material – but it is difficult to tell without being there to see it.  If you smoosh it, can you tell if there is any moisture at all?  Chlorophyll (the green in the leaf) can last a long time, especially in woody plant leaves that are waxy, which this looks similar to.  But it is rare.
But there is certainly a chance of it happening – I am very excited to look at this when it comes back!  I’ve not seen anyone find something like this before!
Good Work!
Thank you so much
Carlyn

Today in class I poured off some of the water from our flotation analysis of the last of the bag. I found many species of snails with shells from 1-3 mm in length.  The next step is to research the names of these snails.

Sea shell found by Maeve Gleeson and AnnMargaret Mealey

Today, AnnMargaret, Maeve and I were looking at some really cool rocks that a almost see through. Mr. Theuer told me they can be angular, sub angular, sub rounded, and rounded. He told me that the more round they are, they have been pushed around by water. I thought this was really cool. More Coming Soon!!! 😃😁
