  1. Hello guys, Summer is nearing its end so I decided to go and hunt the Niagara Escarpment of Hamilton, Ontario. The exposures I checked out at a creek ranged from the Cataract Group (early Silurian with the Whirlpool formation at its base and it sharply cuts the Queenston formation) all the way to the Clinton Group. Here is a pic of the Manitoulin formation, which is a part of the Cataract Group and is above the Whirlpool sandstone/formation. Above the Manitoulin formation is the mostly shale dominated Cabot Head formation. The Manitoulin and Cabot Head formations will contain fossils like this rock below. On these rocks one can find many small rugose corals and brachiopods. I move up stream to come across the base of an exposure with much rubble that comes from the Grimsby formation (Cataract Group) all the way to a portion of the Lockport Group. This stretch also covers the Clinton Group. A rock from the Rochester formation. This below is an interesting trace fossil as it reminds me of the Bergaueria trace fossils I used to find in the Georgian Bay formation of Toronto, Ontario. This one below belongs to the Cabot Head formation. If anyone thinks I should have kept this trace fossil, let me know what you think. New material is always falling at the base so it can be a nice ground to hunt for fresh material, even though some Silurian formations in this part of Ontario can be unfossiliferous. The creek ran on trickle since it is summer and made it easy to explore the creek. One of the finds I came across was this slab of pentameriid brachiopods (Pentameroides subrectus?) from the Reynales formation of the Clinton Group. In as much as I wanted to take home the entire slab of steinkerns, I decide to just smash it (as I am limited in space) to keep the more complete valves as finding nice complete valves from this formation is hard to find in my experience. But for real, this slab was also not eroded, had nice detail and would have made a nice display piece have I got the space. I also have the tendency to keep the best specimens I could get my hands on when I go fossil hunting at my locales. Here is a rock I decided to take home from the slab with at least two complete valves of pentameriid brachiopod. Here is one of the valves I took home from smashing the slab. Smashing the rock was hard and bits of it went flying as I tried to smash it up. The Reynales formation is mostly dolomitic limestone and these pentameriid brachiopods I took home also had pyrite on them.
  2. I made a trip today to Albion Falls in Hamilton, Ontario, Canada by public transportation. Albion Falls is a classical waterfall that cascades over the Niagara Escarpment in Hamilton, Ontario and is 19 metres high. The waters flow north along the Redhill Valley as Redhill Creek to empty to Lake Ontario. Once a popular tourist destination, climbing up the waterfall is not allowed anymore due to paramedics having to rescue irresponsible tourists who have hurt and died from slipping and falling. I mostly ended up checking out the Grimsby Formation which is nicely exposed near the waterfall. There are walls of exposure as the water meanders down from the falls, revealing nice explorable spots. The Grimsby Formation is part of the Cataract Group and dates to the early Silurian period. The Grimsby Formation is not popular as it is not fossiliferous. I’ve had better luck finding fossil animals in the Manitoulin and Cabot Head Formations at the Devil’s Punchbowl in Hamilton, Ontario. The reddish maroon bottom part of the exposure is the Grimsby Formation. It is mostly red/purple shale mixed with the same coloured sandstones. Here is a pic showing how the Cabot Head Formation of the Cataract Group progresses into the Grimsby Formation.

    Paleofavosites asper

    From the album: Hamilton, Ontario Fossils

    Paleofavosites asper (d’Orbigny, 1850). Coral squashed on grey shale. Found in the Manitoulin Formation of the Cataract Group on the Niagara Escarpment. Locality is the Devil’s Punchbowl, Stoney Creek, Hamilton, Ontario. Early Silurian.
  4. After going around in Hamilton, Ontario looking for a river/creek to check out the iconic Niagara Escarpment of the city, I decided to check out the Devil’s Punch Bowl which is located in Stoney Creek, Hamilton. Most of the waterfalls located in the old city of Hamilton are out of reach/barricaded/no-go zones with fines for trespassing because of safety reasons. Nearby Albion Falls and other waterfalls like Tiffany and Chedoke in the old city of Hamilton cannot be explored close up because of the tourists and locals that have died and severely injured themselves from falling while on the cascading waterfall. Today I was surprised to realize that the bottom of the Devil’s Punch Bowl was unbarricaded and so off I went to explore it. It seems the only place that tourists and people go to when visiting the Devil’s Punch Bowl is the observation deck at the top of the falls which offers a nice view of the falls. This is evident as I noticed that there was barely any trash at the bottom of the gorge and down river. The height of this falls is 37 metres. Today the fall is dry with no water. Theres a large Timmy’s cup on the bottom right for size comparison (it isn’t mine though!). There are various formation in this rock exposure of the falls and assigning loose rocks from the ground to the right formation can be a hassle.
  5. Yesterday and today I scouted two waterfalls on the Niagara Escarpment in Hamilton, Ontario. I only intended to check on what the winter has eroded away but I ended up finding some small fossils. The first waterfall I visited was the Devil’s Punchbowl. I only visited the lower falls (the one that runs over the Whirlpool Formation) of the Punchbowl as the creek of the fall has yet to dry up from warm weather. I ended up finding some small brachiopods and an orthocone on the Manitoulin Formation of this fall. Wow, I dont think an orthocone has been reported on the Manitoulin Formation at this locality yet. I might have to go back to those papers. I think this could be a Michelinoceras sp.
