Sussex Field Work (2015)

Recommended Posts

Sussex is an interesting region in terms of geology and paleobiology. An amalgamation of different formations crisscrossing the larger Moncton Basin, this area was the target of study by local and foreign interests. Sussex is known for its potash mines, but one shouldn't forget the importance of the rich fossil localities doting the region. One such discovery was probably evidence of Canada's oldest forest, which is of significance.

Matt Stimson, along with other professionals in the field, did some work in the area. I've had the chance to assist on occasion in a few field trips. The work done in this region is still ongoing and soon to be published. This time around we decided to target an area I've never gone or attempted to go yet. I'm used to quarries, but this time we would be spending the day at a road cut.

Matt getting ready

It was a few days after the Christmas holidays so it was kinda cold. The wind was nippy but we were lucky that ice hadn't formed yet on the ledges and that snow hadn't blanketed the area. The day started kinda grey but by the afternoon, the Sun had come out. It was a welcome event as the wind was freakin' cold.


We made our way to the center cut. Traffic wasn't much of a factor as you can see cars coming from miles away, and plenty of space to park my car off the road.


Area of Research: The rocks here are comprised of several units of interbedding sandstones and mudstones. Within these units, some several meters thick, are shale layers. Within these layers are indications of both plant and aquatic biota. Traces of fish material, scales, teeth, bone, are contained in some of the layers, forming some small limestone lenses and strata. Other areas along the cut feature plants. In all this mix, there are trackways. The work in the area is ongoing so all the data hasn't surfaced yet until publication sees the day.

The cut showed signs of faulting, backed by folding.




This looked promising


We found many invertebrate trackways such as diplichnites and rusophycus. Most were very well preserved, even though exposed to the elements. From traces to scales and teeth, the record showed a high level of activity, condensed. The work goes on.



We reached a spot where we encountered plants. I don't remember if these were referenced or cataloged previously. The preservation was fair, and we were able to find a good number of specimens. The New Brunswick Museum lab will have new specimens to work on by the end of the day.

We've covered only a small portion of the area. Different zones have been targeted for future study. Having done work for the past Summers, I can see why Sussex and its surrounding localities have been visited. The amount of fossils in the around is astounding, especially when talking about trackways.

The work continues...

That geology is just amazing!

Thank you very much for the glimpse of it, and its former denizens!

Nice stuff here, and Matt looks like he is freezing his butt off. LOL

Somehow missed this until now...

Did you collect those roots in the 3rd-to-last pic, and if so, how? I've never seen anything quite like it, seems like it would be worthwhile, if possible.

oof sorry for the late reply xP  Been missing in action for a bit.  Those exact roots weren't collected, but there are other samples that have been collected for the Stonehammer Lab (New Brunswick Museum).
