Paul Krohn's Virtual Tour

July 3, 2020

Buffalo Geological Society Member Paul Krohn has invited us to host his “Virtual Tour” articles, originally written for his personal Facebook page. Paul is from North Tonawanda, New York and uses Facebook to share his photos and insight from local places of geologic interest.

I had a request to post pictures of the type of glass sponge fossils that can be found at the site I visited yesterday. Here are the two partial specimens I found there 2 weeks ago. In one shot I cobbed the two specimens together to represent what a complete specimen would look like. The pencil is for scale. The window screen like impressions in the rock are all that remains of the sponge. In life these structures were composed of a fibrous silicious material that somewhat resembled the mantle used for a Coleman camping lantern. Like a mesh. The sponge was rooted in the ocean floor. In life it drew food particles in the water in through the pores in the side known as ostia and expelled water through an opening at the top known as the osculum.


For any of you who have been suffering from the oppressive heat and humidity we are currently experiencing I figured I’d post these shots I took a couple of winters ago so you could think about the other alternative.


These fantastic ice formations were photographed along the Lake Ontario shore line on the Eastern end of Wilson Tuscarora State Park in Wilson NY. It was an absolutely frigid January day and I literally had to crawl on my hands and knees over an incredibly slippery icy area to get out to where these formations were to get these shots. Beautiful as winter can be, I’ll take the heat.


Archived Virtual Tour articles will be posted every Sunday and Wednesday until we catch up to the most recent date.
