2016 Vermont Concretion Trip

The Mothers Day trip to Vermont for Clay Concretions was attended by 9 Club members and 4 members of the University of Vermont. The morning started out with overcast skies, turning into a heavy mist with some heavier showers mixed in. The weather did nothing to dampen our enthusiasm and once we had all hands at the meeting spot we set out to the first of 3 locations. The collecting was incredible at all 3 locations even with the rainy conditions we started with. The sun finally showed itself about 1:30 and the rest of the day was beautiful. The small group went home with much heavier vehicles than they arrived with. The incredible range in size and texture of these Clay Concretions is amazing. Size varies from a ¼ inch to feet across, ounces to hundreds of pounds and from fine clay to huge armored pieces covered in rocks that are difficult to chip off with a hammer.

Because of last year's incredible leaf fossil find by CVMC member Dynelle Longto we went back to that location first. The people from UVM were the ones that made a positive identification of the species of leaf that was found inside the clay concretion found in 2015. We invited them along on this trip as a thank you for identifying the 2015 specimen and so they could visit the site and look for more fossil evidence. They did find some more organic material (parts of sticks, leaves and seeds) in a Varved Clay layer up high in the pit face, hopefully it's enough for some carbon dating. We didn't find any other leaf fossils but we didn't have any trouble getting our fill of strange and beautiful concretions.

We had a great time with you all on Sunday. We didn't find any similar fossils to the one in the concretion, but we did find an interesting sand layer containing lots of small pieces of wood and some small leaves and seeds. Not sure what they are yet. Attached are some photos. I'll keep you posted if we figure out any names for what we found. 

I put a piece of the wood on a slide and looked at it under the microscope. Cellular structure is definitely preserved and the wood, at first glance, looks like it is from a gymnosperm.
