Return to Streetsville, Mississauga, Ontario


JUAN EMMANUEL

Recommended Posts

Yesterday the weather in my area hit above the 20 degrees Celsius so I dared myself to go to Streetsville in Mississauga to visit a fossil site I have not been to in 2 years. I now live in Hamilton, Ontario so travelling to Streetsville was intimidating for me using public transit from Hamilton to Streetsville.

I have not been to Streetsville by the Credit River ever since I moved from Etobicoke to Hamilton, Ontario and I miss collecting in this vicinity.

 

But I made it. :))

 

I took pics of exposure sites as these sites are mentioned in one of the literatures describing the Georgian Bay formation.

This site exposes the Georgian Bay formation, Upper Member.

As usual erosion reveals a plenty of fossils here. Bits of corals, stromatoporoids, and algae are everywhere. Favistina, Prismostylus and Stromatocerium are everywhere, along with unidentified bryozoans and Holtedahlinas/brachiopods. These are animals found in the Upper Member of the Georgian Bay formation. 

I found an unidentified orthocone. Could be a Spyroceras. 67E73A12-C588-4A14-A2FA-252D36327E6C.thumb.jpeg.f5dfff7aca097b463f31c6ce248ad7dd.jpeg

Lots of Favistina calicina corals.

Here is a nice Stromatocerium huronense mound I chose to keep.

A Favistina calicina displaying a round growth form.

It puzzles me why a Stromatocerium would display these bumps on its skin. Could it be a Labechia sp. instead??

Some of the Stromatoceriums I’ve found.

Here are some site pics.

Since these exposures are out of reach for the ordinary public, some folks went up to me asking me what I was doing. 

Here are pics of the Credit River where the exposures I showed above are located on. To the uninformed onlooker it would seem I waded across the river just to get to these exposures I showed above, which is not the case for me.

Thanks for reading!

Thanks for sharing! :)

Super pics and finds! 

I have several specimens from Etibicoke Creek and Mimico Creek, but the fauna where you were is very  different.

Love those corals and stromatoporoids but i'm most interested in the brachiopods, Holtedahlina and any others. :wub:

Any chance of a pic or two, please?

Great finds. Thanks for the photos. I'll bet the smallmouth bass fishing there is pretty good too.

 

 

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

Here are some of the specimens I decided to keep. 

Stromatocerium huronense sponge. Various growth forms.

A Prismostylus sp. A fragment of the calacareous algae.

Unfortunately, most of the Holtedahlinas are only fragmentary meaning whole specimens with the both valves present are hard to come by in my experience. So as a result I didn’t get to focus on those as much.

Yes this area seems like a popular fishing spot. At the day I was fossil hunting there, there were 3 fishing folks on the same side of the river bank as I was. 

It doesn’t seem like they’ve encountered a fossil hunter like me at this location before but they just let me go on with my own business.

i don't know, river looks ominous, treacherous in fact. Glad you are safe.

Good stuff! Many stromataporoids display mamelons (the bumps) on the surface as do some bryozoans.

What a tremendous thread...I'd love to visit there when the water levels are lower.

 

Great photographs!
