Sundance sea was not quite inland as it had a northern and southern opening. What is BC was merely a chain of islands

I think that probably at one time or another, every place on earth was once under salt water.
The St-Laurence river valley was also an inland sea.
When they drill down in parts of Montreal, they bring up sea shells.

I used to find petrified palm trees about 900 meters into the bowel of the mountain when mining in BC.

Also one of Canadas best finds of dino tracks is there.
It was discovered by accident when a huge chunk of the mountain failed and when the rock stopped sliding there was literally millions of tracks exposed.
National geographic came and documented it.
I have video of some of it failing as i was below it at the time.

Were those trees calamites? The plant life at that time was mostly lot of giant tree ferns and plants that belong to the same family as scouring rushes. Angiosperms weren't as common or widespread as they are today.

Hard to say but I found more fossilized trees then ferns,some were over a meter wide and allmost fully intact.The mist mountain formation is also flipped upside down there so the old rocks are at the surface and the younger ones are a mile down.

The Elk Valley coal comes from a package of rocks known as the Mist Mountain Formation and is the oldest record of terrestrial (non-marine) rocks in western Canada. The Mist Mountain Formation rock layers straddle the Jurassic-Cretaceous boundary and were deposited approximately 135 million years ago along the coastal region of an inland sea that stretched from the Arctic Ocean almost to the Gulf of Mexico.

By comparison, much of the coal that is produced in the Tumbler Ridge area is approximately 100 million years old.
